What's YOUR method of growing hellebores from seed?

It's been mentioned elsewhere that this would make a good post as we can all get involved and compare our different methods used to grow hellebores from seed. I'm happy to start the ball rolling so here is how I grow hellebores from seed. Bear in mind that I'm in England so the methods that I use suit our climate. Also, it would be a brave person to claim that their methods are the only correct ones. Hellebore seed is very flexible and responds to many different techniques regarding germination. As more and more people share their methods, this will become apparent.

I sow seed as soon as I have it. For my own this will be early June and for bought seed this is usually mid July. I sow the seeds in square 1 litre pots, 20 seeds to a pot. I use a peat based multi-purpose compost with a little perlite added for drainage. I sow the seeds approx. 10mm deep and top-dress the pots with a 5mm layer of fine grit, just to stop mosses forming on the compost surface.
After watering the pots, I then put them on the floor underneath the staging in the (unheated) glasshouse.

I check the pots every couple of weeks just to make sure they haven't dryed out. Germination usually starts for me in December and carries on until March. When I move the seedlings into their own pots depends on how many seeds have germinated in the pot. If all or nearly all have germinated (H.x hybridus seems to germinate all at once for me), I move them into 3 inch pots at the seed leaf stage. I tip the whole pot out on to the bench and break away the seedlings one by one, making sure that as much compost as possible is surrounding the roots. I find that moving the seedlings this early spurs them on and they soon produce true leaves.

The treatment for species is much the same as above except that I find that germination occurs over a longer period of time. Some seedlings may be well on their way to producing their second true leaf and other seeds in the same pot may be just starting to germinate. Rather than potting the seedlings up in multi-purpose compost, I prefer to use a soil based mix with sharp grit added to aid drainage.

The young plants stay in their 3 inch pots until May/June when they are then moved into 1 litre pots. The hybrids and a few of the species will stay in the 1 litre pots until early September; they will then be planted out into rows where they can be studied and compared with each other. Most of the species are slower than the hybrids and therefore will stay in their 1 litre pots until the following year; they are then either planted out or moved into a 2 litre pot.

And that's how I grow hellebores from seed. Not as complicated as some methods but I do like to keep things simple and I'm satisfied with the germination percentage that I get.

If you use a more complicated method or even a more simple method, then stick with it if you have a satisfactory amount of seeds germinate. If not, then perhaps this posting will be a good place to pick up some tips.

Best Wishes,
Tim

RE: What's YOUR method of growing hellebores from seed?

Tim,
I am a very lazy gardener and like to keep things very easy too. I've only grown hellebores from seed once so far but had good luck. I live on the west coast of Canada in about zone 7-8 and have only grown hybrids. I sowed the seeds as soon as I got them (June)into flats filled with a mix of composted mushroom manure and leaves, sand and peat. I top dressed with sand and laid a layer of toilet paper over the flat to help hold moisture. I placed the flats under a tree in a flower garden in part shade until about Nov-Dec when they started to germinate.They got watered with the rest of the plants in the flower bed. We have a lot of problem with slugs and rabbits so I placed an old window mesh screen over the flats and basically forgot about them until the fall. I checked them regularly until they started germinating. I then moved the flats into an unheated greenhouse for the rest of the winter, again checking regularly to make sure they were kept moist. The reason for the move was to keep the slugs away, because once they germinated I had to remove the screens and I can't use any slug bait outside because of the cats and dog but can in the greenhouse. They did well and in the late spring they were ready for 4" pots. I kept them in the greenhouse that summer and winter. The following spring I moved them into 1 gal pots and moved them back out under a tree. They spent last winter there and are doing very well. Out of 120 seedlings I only lost 4! I hope they bloom next spring.
I'm not sure what % germination I got but it was much better than I thought it would be considering I didn't put a lot of effort into it.
I have noticed that this year I'm finding new little seedlings in the pots with the older plants. Next time I will keep the flats longer to see if there are more slow seeds.
With my own plants I collect enough seed to share with others and the rest I let fall under the plant to germinate on their own and dig them up when they are large enough to handle.
This system works well for me.

RE: What's YOUR method of growing hellebores from seed?

Tim,
I collect my seed and plant it the same week. When I purchase seed I ask for fresh seed and when I recieve the seed I plant right away.

Seed collecting time here is at the end of June. The seed get sown into 8 inch wide by 5 inch deep plastic pots (with about 60 seeds to a pot). I like to use Fafard germination mix, press the seed into dampen media cover lightly, and then cover with a course washed sand (about 1/16 of an inch). The potted seed is then top-watered gently and allowed to drain for a day. After being allowed to drain and dry for a day, the pots are place in a germination chamber. This is just a small structure on top of a bench in my potting shed that has a clear poly-cover suspended over potted sown seed. Here the sown seed remain with very little attention, other rapidly germinating seeds are also in this chamber, so every day I usually look in to see what has germinated. The pots with the hellebores remain here until November and usually needs no additional water or care. In November after a number of chilly nights and days with some freezing in the pots tops the hellebore seeds start to grow roots. At this time they are removed and taken into the house and they spend the winter on a masonary floor in front of glass sliding doors with a southern exsposure (so that there is plenty of direct sunlight). They stay here with very little care at a moderate tempature and they slowly emerge and produce their seed leaves. I water when they appear to be quite dry with cool water only about every 5 to 6 weeks. In March they have their true leaves and in mid-April they are transplanted into 4.5 inch deep by 4 inch wide pots and placed outside in a sunny --but shady-- spot, grown on until mid-August, and then they are planted into the garden.

I have always been amazed at how tough the seedlings are and the small amount of care they need. Last night my seedlings outside were exposed to a temp of 22deg F. and this morning they looked great.

Always Gardening,
Bruce

I sow Helleborus seed as soon as they are ripe. I just sow them around my grapewine in my unheated greenhouse and cover with a little soil and then I pour on some water. When the plants are big enough I just plant them where I want them to grow. I never dig them up and place them indoors at any time.

RE: What's YOUR method of growing hellebores from seed?

My method is quite simple; but it is not highly controlled in the germination phase, and it is likely not sufficiently sterile or pest-proof (until the first winter) for some environments. Each season I prepare new beds by extending the existing ones. I turn the soil and add amendments (in my case some sand and lots of compost). I sow seed whenever it is fresh and allow it to go through a natural warm-cold-warm period outdoors.
Because most hellebores successfully self-sow in my garden, I only sow seeds that I expect to be interesting (Perhaps due to hand pollination or seeds from a particularly valued parent). After germination and a season of growth, I transplant the seedlings to pots in a more sterile mix and bring them indoors to grow through winter under lights and give them some added nutrients.
The germination time may be longer than if you were to create an artificial warm-cold-warm cycle, but the time is made up for by the "extra" growing season they get in the following season under lights. From my experience, plants of the same provenance that are left in the garden through winter are a third the size of the plants brought indoors and have half the number of leaves on average by the following winter.
In this system the plants are transplanted twice: once from the garden into pots/containers and again into the garden or larger pots/containers the following year.


 o
RE: What's YOUR method of growing hellebores from seed?

You guys have developed Hellebores seed sowing into a fine art. All I have done, for years is to sprinkle the seed on the soil as soon as they are "ripe". They usually start popping up in January, and by May, are sturdy by tiny plants. Now, we are talking H x hybridus here.

Now that I have a few species hellebores, I most likely have to follow your footsteps and take hellebores seed germination more seriously.


 o
RE: What's YOUR method of growing hellebores from seed?

I checked the winter sowing forum initially for information on Hellebores from seed. Winter sowing is an interesting technique and there are reports of winter sowing success with Hellebores. From the information above, I assume that fresh seed is important and any seed I acquire now, January, would be "old"?

RE: What's YOUR method of growing hellebores from seed?

I have some 'Lady ' series Hellebores from Jelitto Seeds, Germany doing fine in real one gallons. Got the seeds midsummer 2000. Planted them then, and they sprouted early spring 2001.
This winter I purchased Jelitto's H. niger 'Maximus'. The seeds arrived now to my surprise. Question is, will doing warm moist stratification 6 weeks followed by 6-8 cold get these to germinate? Or should they be planted fresh only? How does stratification work on these? The 'Lady' series are H. orientalis whereas these winter delivered seeds are H. niger, if it makes a difference.


 o
RE: What's YOUR method of growing hellebores from seed?

I would place them in damp media right away for at least 6 to 8 weeks and then into the fridge crisper until they sprouted.

RE: What's YOUR method of growing hellebores from seed?

OK Here goes-My stock plants are one very large and beautiful dark red (with some spots) Sunshine oriental hybred, and a variety of very good red pink and white Royal Heritage Strain orientals. These I have been hand polinating for some years and the results are begining to show. This year I have offspring that are better than any of the parents, Ya Hoooooo finally!!! When the first seed capsul splits I gather all the capsuls by cutting them off the mother plants and put them in marked paper bags .I want to know which ones are which all the way to flowering in three years. While the seed caps are drying in the paper bags I start preparing the plug trays for planting. I use a comercial seed starting mix (available at any good garden center)It usually takes only a few days for the seed caps to open and the seed to fall to the bottom of the bag. I start sowing right away then cover it all with grit. The grit keeps the ants from getting the seed.It also helps to prevent moss growth and keeps moisture in the medium. Grit is heavy and stays on top of the soil even when I get a little caried away with the water pressure. My experience has shown me that once the seed coat begins to wrinkle the germination will be almost nothing. I prefer not to plant seed that is older than two weeks but I have stretched it to three weeks with satisfactory results. The seeds I planted last june/july are germinating now.Pinks always seem to be first out of the starting gate with reds following and whites last. Last year I planted some seed of niger and purpuresesce also. The purpuresence is coming up but no sign of niger yet. I prepared plug trays yesterday for seeds that are on the way from Tasmania. But I digress.----Seeds germinate in Jan?Feb. Since they are in individual plugs I don't have to do anything with them until June when they are big enough to be moved to deep 3" pots. And so on and so on until one fine morn, in about 3 years we get to see the "finished" product. It is never really finished because as soon as I see it I am planning the next cross with the pick of the lot or deciding to let this one go and keep that one and so on and so on. It's enough to keep one from ever getting old. I guess I should mention that I live in zone 7 and my plug flats are in an unheated greenhouse with no ends (22 degrees F last night). Happy Planting J.

I received fresh seeds last spring and planted right away as instructed...notta, nothing happened. Seeds are still in their pots (I'm determined aren't I..lol) Should I put the pots into the fridge for 6 weeks to now produce a cold spell or are the seeds useless now?
Any information would be helpful..

RE: What's YOUR method of growing hellebores from seed?

Some of you have mentioned that your get blooms on your H. x hybridus's in the 2nd year. I've only grown one batch of seeds so far and they took 3 full years to bloom and some are still not blooming yet. I leave my seedlings outside because of laziness and lack of time. I do have 2 large greenhouses I use for propataing shrubs and usually have room left over. Would it help if I brought them in over winter? This is an unheated plastic covered greenhouse with doors. I have lots of new seedlings coming up and it would be nice to speed up the blooming precess. I'm not that young any more and don't have forever to wait to see the results especially if I'm going to hand pollinate.

 o
RE: What's YOUR method of growing hellebores from seed?

Yes, the more growing time they have, the larger they become, the less time to bloom.

Once they begin to really grow, they like root room and fertilizer. If they have cool weather with no frost and have root room to grow with good fertilizing people report flowering in 14 months from seed for H.x hybridus.

I grow the seedlings inside the first winter and in the fall they are planted out to be wintered and I have quite a bit of flowering the second spring. In the third spring they are very large plants and are mature flowering.

RE: What's YOUR method of growing hellebores from seed?

Did anyone answer Brugmansia's question? That has to be so disappointing, no germination at all. Where are the seeds now? Have they had warm cold cycles? Have they been allowed to dry out? I'm just starting out myself, but my understanding is that the seeds need to be moist and have 6 weeks of warm, followed by 6 weeks of cold in order to germinate. If they are dried out, it's going to take longer.


 o
RE: What's YOUR method of growing hellebores from seed?

This was posted elsewhere but I've pased it in as it makes sense when so many questions are raised on this subject, to have a number of answers together.

I hand pollinate and mark the blooms with a bit of wool and a tag giving parentage and date of pollination. I keep a log of crosses made and when I see the first pods splitting, go check for the next ones, gathering the seed just before ripe.( I've had problems in the past with mice eating all the ripe seed.)

I use 1 litre deep pots 5.5" deep by 5" across with a gritty compost, 1 part each JI no3, peat, and cornish grit, filled nearly to the brim with 20-30 seeds per pot then topped off with quarter-half inch of cornish grit.

I soak this from the base till the grit is wet then stand the pots in a deep tray drilled to leave half an inch of water in the base. (slugs cannot cross the water) They sit in this wet cold environment all winter and usually come up with 95% germination in the spring(anytime from December through March, the species generally slower).

I pot them on or plant them out when the first proper leaves have formed, the gritty open compost means that you can shake them out very easily and get a good 4" of root, make sure that the tip of the root is pointing down into your planting hole, (deeper pot 2L deep). Also make sure that the stem does not get bruised as they will damp off quickly.

I have a special raised bed which I clear on a two yearly basis. This houses about 1000 seedlings, I dig in about 50% fresh rich compost into each half as I renew. The seedlings are planted out about 4" apart in batches according to the pots, ie one pot will give about 2ft square planting. In addition to the deep rich soil I feed with half strength seaweed liquid feed 3 or 4 times in the growing season, I get about 25%-50% plants flowering 18mths from sowing depending on the batches(6mths in pot, 1 year in raised bed). The rest tend to take a year longer.

Previous experiments with more than half an inch of water in the base of the trays resulted in plenty of seedlings but they soon rotted off with too much moisture. Without the constant moisture I would get only 30-50% germination, ie if the seeds became dessicated as with stored seed, germination is severly impacted, however as many have noted here and elsewhere, once re-hydrated, germination resumes in the second year(also seen with the few sporadic extra seedlings in the beds planted out from the pots which I tend to rogue out as they may be older seed parentage of which has been lost). If you get seed that is anything but plump and fresh, soak it for a day or so before planting in a moist but not wet environment, if seed has been dry, keep the pot for 2 full seasons before deciding that you've had no or poor germination.
As regards open ground, I get quite a few seedlings at the base of their parents where I have not deadheaded, however I believe the mice can see these off once they get the flavour for them....it's worth protecting your seed trays/pots from mice if you can. I tend to pot any remaining self sown ones up in little pots when they're a couple of leaves big and give them away at school fairs etc as they'll be open crossed and not worth waiting 2 years to see if a very lucky accident(which cannot be re-produced) has happened.
This year I'm not bothering with any hand pollination as I have so many seedlings from last years crossings I have a major backlog of about 2000 seedlings, plus everything was into bloom so early(mid January) that I hardly had time to get out there with my paintbrush.

After all, it's only a hobby(addiction):-) It's the hardy orchids, arisaemas, trillium and paris that really get me going.

Phoebe,

You're right, we all get too wrapped up in perfect technique and miss the simple point.

Sow the seed in a deep pot of just damp, seed compost, leave outside, in a sheltered spot out of direct sun and let nature do the rest.

When they have 1 or 2 proper little leaves, they will have about 3-4inches of root, handle them gently.

RE: What's YOUR method of growing hellebores from seed?

I have found that it works to let them grow where they are, in the soil outdoors, as mine normally self-seed like crazy. I have tried potting up seedlings, but our weather here in coastal B.C. has been a bit unusual - a lot of rain, followed by, say, a sudden drop to -12C for 4 days. I think they hate to be waterlogged. (Graham Rice's book called "Hellebore" mentions that it's easiest to let them grow in the soil as well...) In any case, I lost a lot of first and second year seedlings and even older plants this year. So....I think I'll let Mother Nature do it. I know it's not always convenient, but since I tend to let things grow where they are, even if it's in the middle of the path....it seems to work for me. I don't weed much, either. In other words, half my garden is self-sown. I am looking for fresh seed this June, and I think I'll try an outdoor seed bed out of the wind.


 o
RE: What's YOUR method of growing hellebores from seed?

Hellebora, All well and good but when do you clear these seedlings out to make space. My full size plants measure about 3foot diameter and 2 foot high. Any seedlings struggling under that are either never going to achieve their potential, and die out or will impair their mothers space, ending with stunted or spoiled plants at best. Quite apart from all the other companions that grow between the plants when the leaves are off in the spring.

No I would suggest that your transplanting technique needs a bit of practice, you shouldn't lose seedlings like that. They hate waterlogging and will most certainly die from that, neither do they like being baked dry, cool moist and careful handling, potted in deep pots with the root pointing downwards and you should retain 100%.

RE: What's YOUR method of growing hellebores from seed?

Here's something not addressed here!

I asked in another thread about my seeds I purchased. They're packaged, so I have no idea now not "fresh" they might be.

Lisa_H suggested I pot them, cover them and stick them outside, similar to the winter sowing I've been trying.

Would these packeted seeds need time in the fridge with some wet paper towel do you think? Or just fridge time and into the dirt?

I really love these little things and can't wait to see if I can get blooms!

Thanks,

I just received fresh hellebore seeds from a wonderful trader (she sent them in a moist coffee filter in a zip-locked bag). I'm still a little confused: do I just pot them up and let nature do its work? Or place in fridge?

RE: What's YOUR method of growing hellebores from seed?

Hi, I am completely new to gardening and I have ordered some Helleborus orientalis hybrid seeds (currently awaiting their arrival). It said on the packet that it might take a year to germinate and that they should be kept in a temp of 70-40F 20-25C.
Question.. can I leave the seeds to germinate in a completely covered pot -I mean covered with an object that doesn't let through any light at all, or do they need some light to germinate?
I ask this because I have a little, hidden from the sight, window in the house, window where I could place the flowerpot and it wouldn't be such an eyesore for a whole year! Problem is, that window gets direct sunlight for a few hours each day and it gets really warm. Now that would be perfect for the required temperature, just not sure if it's ok to completely cover the flowerpot, so it's completely dark for the seeds.

Thank you for your help!

Your window is inside? I don't think you'll have good results without giving the seeds a range of temperatures. A warm moist period (2 - 4 months), followed by a moist chill of approximately the same number of weeks, raising the temperature to warmer but still cool is the general method of sowing hellebores. If the seed has been allowed to dry and has been stored, more than one cycle of temperatures may be needed; fastest germination occurs with very fresh seed. The easiest way to do these is often sow, covered with sowing medium, then top the pot with grit or fine aquarium gravel to deter any algae or moss from growing...place outdoors and water occasionally if there has been no rain.

You can try imitating the course nature would take by using your refrigerator for the moist chill...

Helleborus argutifolius, croaticus, dyclophyllus, dumetorum, foetidus, lividus, multifidus, niger, odorus, orientalis, purpurescens, vesicarius, viridis, and x sternii , Pour hot water over seeds, let soak 1-3 days until swelling noticeable. Sow at 22C (71F) for 6 wks or more. Move to -4 to +4C (24-39F) for 6-8 wks. Then raise the temperature to 10C (50F). If no germination in 4-6 wks, repeat the cycle from the beginning. If the warm/cold cycles were not long enough, a new warm/cold cycle is needed. short viable.

RE: What's YOUR method of growing hellebores from seed?

I used small mason jars and filled them half full of wet perlite and put the seeds on top. And I covered the jars with foil. After a month I put the jars in the fridge, that must have been five or six weeks ago and the seeds are starting to sprout now.

I plan to plant the one pictured very soon, but when is the best time to plant? Should I plant the seeds as soon as they show any sign of sprouting and move them to room temperature? I can see that the seed coat splits and that means they are going to sprout so I could plant them then, or is it better to wait another week or two until they look like the one pictured?

This seedling is still in your refrigerator? It needs light.

As for the rest of your question, I haven't handled my germinating seeds when that immature, I sow in potting medium and don't pot individually until they have one or two pairs of true leaves. But, they will have no drainage, no nutrition in perlite, and no light in your refrigerated mason jar, and I would pot them quickly.


 o
RE: What's YOUR method of growing hellebores from seed?

This is a great post for all sorts of growing techniques.

I am wondering how to pick the best outdoor bed to start the seeds. For instance, can they be started under a pine canopy if they are towards the edges and the soil is prepared correctly? Will they get too much light if planted under trees that lose their leaves? Will hellebores do as well under many shaded different types of shaded areas?


 o
RE: What's YOUR method of growing hellebores from seed?

I'm brand new to sowing seeds. I have a weird question. I picked the first batch of seed pods in late May when I noticed them splitting, but when I opened them I was lucky to get 1 seed from each pod, some had none but just a sprinkle of these super-tiny specks of seeds. I'm guessing I should be planting just the larger, pepper-kernel-sized bits but why do some pods not produce seeds? I just picked a second batch and found absolutely no seeds. Were they not pollinated? Should I expect to find multiple seeds in each pod?

Thanks for any help and all the hints listed above.

Some years are better than others for seed set, weather plays a big part - drought can be especially hard on seed formation. In this mild moist climate, I can usually count on large quantities of seed, but I do have one hybrid yellow flowered plant that never provides seed, not in the five years or so it's been producing flowers. Lots of flowers, no seed.

The seeds are shiny, black, and there should be several per pod.

Here is a link that might be useful: Photo ripe pod and seeds

RE: What's YOUR method of growing hellebores from seed?

I'm one of those gardeners who can't germinate anything outside over the summer because I forget about them, etc. So my Hellebore germinating method is this:

I get my seed from a seed exchange in February. So my seed is not strictly fresh. Hopefully it has been kept in a cool place refrigerator) until I get it. This is usually the case though I have gotten some that had desiccated and could not germinate.

I sow in small baggies in damp (not wet) perlite and let the bag lay on a counter somewhere at room temperature 8 weeks or so. I check the moisture level whenever I think of it. Then I put them in the back of the refrigerator until they germinate. That happens 4-6 months later. Again I check the moisture level when I think of it. I pot them up when I see they have roots, sometimes they also have a leaf or two, sometimes not. I put them in individual pots and grow them on cool.

I sowed some in baggies of perlite in late April, put them through a warm and cold moist stratification as described above and they germinated last month. They are potted and growing along out on my porch in the shade. (I remember to water them if I see them on the porch.) I suspect they may be too small for me to feel comfortable putting them in the ground this fall but since I sow seed and grow cuttings throughout the year I'll put them under lights in my unheated basement until time to plant them out in the spring. If I hadnt forgotten them and had bagged them in February they would be large enough to go out this fall.

As to the question of no seed in the pods, know that some Hellebores are sterile. I have one, a species Hellebore, that is well over 20 years old and has never produced any seed. It has however produced divisions so now I have 4 plants instead of one. I may try separating them one day. The rule is dont try to divide species Hellebores. They dont like it and are likely as not to die. So I'm holding off.

What a fun thread.


 o
RE: What's YOUR method of growing hellebores from seed?

OOPS,

I meant to say I put the seed in baggies with Verimiculite - NOT perlite. I use damp vermiculite.

I accidentally sent two packets of hellebore seeds through the power wash cycle of my washer, complete with hot water and bleach (they didn't go through the dryer). I didn't have high hopes for them but gave them warm/moist treatment followed by cold stratification, and they germinated much more quickly than those seeds I didn't wash, also for the first time in growing hellies from seed, I had almost 100% germination.

I wouldn't recommend it exactly, just thought it was interesting.

kms, I haven't done that with anything as expensive as hellebore seeds, but I do admit to washing Nigella Miss Jekyll and to putting those through the dryer in jeans pocket. They germinated too :)

Evonnestory, If you are still following this thread (!) hellebores do well in varying degrees of light. If you are growing species, you can search for specific information on each of them. As for the x. hybridus, it is advertised as a shade plant, but here in zone 6 mine have thrived in varying degrees of sun, including glaring afternoon sun. I'd be more careful in warmer climates.

I'd take in to consideration competition with tree roots though.

RE: What's YOUR method of growing hellebores from seed?

i live in the rockies, and i would just love to grow hellebore, but i can't seem to get the seasons right. frost doesn't really go till mid-may - i have two precious plants which are now sleeping under gauze under straw under burlap. i'm hoping that they survive - i won't be able to check on them for a month at least.
does anyone know about hellebores and how to help them survive the harsh winters in the Alberta/BC border? i'm trying to grow some from seed, but once again, the seasons are against us, the summers are so short. help!
