Anyone else growing or planning to grow exotics?

Posted by bill_ri_z6b (My Page) on

As great as New England gardening is, with all the variety of what we can grow, after seeing the lilacs, forsythia, dogwoods, apples, cherries, tulips, Japanese maples, Rhododendrons, Hydrangeas etc. etc. etc. for over 60 years now, I crave something new to add to these tried and true plants. With an eye toward ecology and water conservation, what about xerophytic plants? Many types of cactus can grow in New England, along with Yuccas (beyond the common Y. filamentosa), ice plants, and newer sedums and sempervivums. What about some new and interesting broadleaf evergreens, like hardy Southern Magnolia, Gardenias, Camellias and Aucuba? Perennials and vines too. There are hardy jasmines and Gelsemium, Agapanthus and some ginger relatives. Am I alone in this quest to broaden the plant selections for our area? Or does anyone else share an interest?

RE: Anyone else growing or planning to grow exotics?

I wonder how many people are in a warm enough zone to even consider some of these less hardy plants? I think the Cape and the South Shore, and the states to our South, CT and RI, right? I know a lot of gardeners in colder zones who crave a little exotic but often go for tropicals in containers in the summer that they then winter over indoors. I wish I could grow Dahlias without digging them up in the fall.

I try to make my garden low maintenance for the most part and trying to push the zone seems to invite more work to me. [g] But maybe not. Plus I am not sick of NE garden plants at this point. I really didn't start gardening with perennials and shrubs until about 10 years ago, so I am still happy with the variety I have in my own zones.

I do grow sedums and sempervivums and would like to hear about the newer varieties. I am aware of 'Angelina', which I am trying, but I thought that was very hardy. I tried it last year for the first time and it wintered over outside in a pot. I love escheverias. The larger and the darker the better and I plan on creating a large succulent pot next season if I can. Some of my problem is with my clay soil, in addition to my zone. I tried ice plant and it didn't grow well for me. I would love to grow and have tried a couple of the western agastaches that are not as hardy here, that hummingbirds enjoy, but they dislike my clay soil and less than perfect drainage. I was looking for seed for Prickly Pear Cactus at one point, but I never did follow through on that one because I don't have a grouping of plants that it would look right with.

Broadleaf evergreens for shade would be something I would like to explore. Camellias would be something different. The flowers are so perfect and waxy. I love fragrant plants and so does my husband, so the gardenia and jasmine would be interesting. I didn't know there were hardy varieties. Hardy to what zone?

Vegetables would be something I could work up some motivation to try. I am really wanting to try to grow something all winter. Maybe with the use of cold frames.

I think with all the climate changes we continue to see, we probably do have warmer weather in the winter than we ever have before, so it may not be such a stretch.

RE: Anyone else growing or planning to grow exotics?

PM,
I wasn't suggesting pushing the zone. Just trying things that fall into one of two categories: A) They are and have always been hardy in our area (zone 5 or 6 depending on which plants we look at) but for whatever reason they aren't very common or B) They are new cultivars, varieties, selections or discoveries that are hardier than all the former types. A good example of the first group would be prickly pear (zone 4 and possibly colder) and Yucca recurvifolia (zone 6 at least). I have prickly pear all over the slope near and spilling onto part of my sidewalk. The pads sometimes fall off and root so easily. The Yucca forms a trunk, and can get up to 7+ feet. Mine is about 5.5 feet now (Leaves and all, trunk is maybe 3 feet). The second group would be things like the new Camellias (Dr. Ackerman's hybrids) hardy to zone 6. Also, Gelsemium sempervirens "Margarita" hardy to zone 5.

As for your desire to grow cactus, It's true that they don't always look good in a mixed border, but a dedicated raised bed (for good drainage) can be very interesting. Placed in an area of hot summer sun, possibly where watering is not easy to do, would be good. I have dozens of pads that have fallen off and lay all over one of my driveways. I'll be sweeping them up for the trash, but if you want some you'll have growing plants in no time!

RE: Anyone else growing or planning to grow exotics?

Bill, ok, now I'm following you. I am now completely on your wavelength. I would love to grow some prickly pear and try it. They flower too, right? My problem is that I have limited sun in my garden and the places where I have full sun are full of cottage garden plants. But I have a patio behind my garage, that my son uses as a workshop for carpentry outdoors sometimes and it gets a very good amount of afternoon sun, facing west and that is where I was planning to grow a big shallow pot of succulents for this coming growing season. I could grow a nice shallow but large diameter pot of prickly pear right along side the succulents and I could add the pot to my raised vegetable bed for the winter. I do that every year with my mints that I don't want to plant directly in the ground.

I hadn't heard about Camellias that were hardy to zone 6. I will have to read up on those. Flowers in the shade, doesn't it? I just googled that Gelsemium and see that North Creek Nurseries has it. It gets 8-12ft, that's nice and even takes part sun. I have a lot of that. I like that it is attractive to hummingbirds. Are you growing this Bill? I haven't seen it at any local nurseries.

Bill, you are a wealth of interesting information on types of plants that I have not really paid much attention to before. Probably because I have considered them not hardy here. Thanks for the new ideas! Would love to see photos of your garden when you have some.


 o
RE: Anyone else growing or planning to grow exotics?

Oh, and especially that large Yucca. I am curious to see how you have blended it into your landscape.


 o
RE: Anyone else growing or planning to grow exotics?

Bill,
I thought of you when I read this article from Arnold Arboretum’s Arnoldia,"Arnoldolia Seeking Cold-Hardy Camellias by Anthony S. Aiello". Frankly I have just given a gentle nod to Camellias as they certainly require specific conditions. I would be very interested in your response from the article in terms of your specific experience with this plant.
I also have a shopping cart full of zone 7 plants that are new to me but I doubt others are interested in reading about so feel free to e-mail me your spring wish list so we can discuss. Katy


 o
RE: Anyone else growing or planning to grow exotics?

PM2,

Here is a photo of the Yucca. It's more of a specimen in front of the house rather than blended into the landscape.

Yucca

I am growing the Gelsemium. It has gone through two growing seasons and spreading to over 8 feet. I suspect that this year it will fill in more. Hasn't lost a single leaf in the winters so far, so seems totally hardy here.

Fall blooming camellias may be better if you're in a colder area, since the buds won't be subject to freezing like the spring blooming types. But I grow both.

Camellia "Snow Flurry" - fall blooming

Camellia "April Remembered" - spring blooming


I think a cactus "bowl" would be fine. These things are very hardy.

Bill


 o
Katy - link didn't work

Katy,

The link to that Arnoldia article didn't work for me.
I'll try to get a list together this weekend of failures, successes and wish list for the future. When it's done I'll E-mail you.

Bill

RE: Anyone else growing or planning to grow exotics?

Bill, that yucka has some huge blooms! I think you did the right thing with it, to use it as a specimen. It works well and it does sound like it is giving you a lot of pleasure. I wonder how large it will eventually get for you.

Look at the nice shiny leaves on the camellias. I like the double 'Snow Flurry' especially. 'April Remembered' has a very distinctive and pronounced center. They have pretty buds too. I would love to know where you placed them.

And I was hoping that when you had some time, you might start a thread on your trip to The Chelsea Garden Show. Did you take a lot of photos?


 o
RE: Anyone else growing or planning to grow exotics?

Bill,
I have been having a heck of a time with something’s on Mac and others on PC. I hope this link works as I do think the article was really interesting, actually they were all pretty cool. I would love to be a part of a discussion on the exotic beetle’s article.
Looking forward to your list as I think we have many cultural (horticultural) commonalities. I have many if not all of my plants (photos, info, ect) on a blog (great excell sheet) that is private but I think I can open it to you.

RE: Anyone else growing or planning to grow exotics?

PM2,

The yucca could reach 8 feet or more measuring only the trunk, so add about 3 feet for leaves, and another 5 feet for the bloom. But I don't know how long that will take. I planted it in 1997 with no trunk. It now has multiple trunks (4) approximately 4 feet high. I suspect that had I kept it to a single trunk, it might have been taller. I have cut off pups in the past few years and I'll keep those single and see what happens. It makes a lot of side shoots. I'm thinking of potting some up and putting them on Craig's list.

"Snow Flurry" has proven rock hardy for me. Even in the terrible cold of January, 2004 it showed no damage whatsoever. It generally blooms for me from mid to late October and will continue up to Christmas if the weather stays fairly mild. A few nights in the mid 20's may start to bother the flower buds.

My camellias are against a south-facing stone wall. The "April Remembered" does get a bit of the west wind in winter, but I haven't protected it. It did almost die in the cold winter of 2004, but after a few months, it sprouted from thick wood near the base.

I will see about getting some Chelsea photos together. I actually took more at Kew Gardens and RHS Wisley, both of which I actually liked better than Chelsea.


 o
Katy - thanks

That link worked. I'll read it in depth when I have a bit more time.

I'm just finishing up a two-month-long renovation of my living room and dining room. Started with wanting to paint the LR. It was never painted before.....always wall paper or latest was a fabric type wall covering. Well after a LOT of prep to the walls, and finally getting a color that I liked, the carpet look shabby. Since the two rooms are open to each other, the carpet is all one piece, so I had to paint the dining room too. Well, then the LR furniture looked bad, so I had to go out shopping for that. Well how could I not get new window treatments in both rooms? So after many many weeks of work, including pushing the piano into the kitchen so the new carpet could be installed(!) I am about ready to relax! A few more chores this weekend and I'm calling it done. Then I will start on that list.

Bill

RE: Anyone else growing or planning to grow exotics?

It sounds like you enjoy propagating and experimenting, Bill. I enjoy a good experiment myself. It would be interesting to see the difference in size between the single trunk vs the multiple trunk. Wouldn't it be a surprise to find they both became equally tall? That yucca is going to be more like a tree! lol I guess my question was more if your plant will reach it's potential in what I presume is a zone that is colder than it's normal habitat.

I had no idea a Camellia would bloom in mid October. How fun would that be to have blooms on the Camellias at the same time my chrysanthemums were in bloom. Well, you've piqued my interest enough to make me look up the new hardy camellias and I see that some of them are supposed to be fragrant too. I found an article on the Camellia Society website on the Ackerman hybrids, that 'Snow Flurry' looks like a great choice and the best of the white IMO. I also like the looks of 'Winter's Dream'. I see they are recommending winter protection the first year or two. Anyway, I am going to have to give this some thought before the spring. I may have a place for one. I don't have a nice stone wall facing South, wouldn't that be nice to have. :-)

I can't think of something I would look forward to more than drooling over photos of gardens in England while looking out the window at snow. [g] Can't wait.

RE: Anyone else growing or planning to grow exotics?

Bill, that April Remembered is gorgeous! Thank you for sharing it with us.

When I first read "exotics" I thought of tropicals, which, surprisingly, don't do much for me. My MIL loves them and is always asking either my advice or my opinion - the first of which I can't offer and the second of which I don't want to, lol, to spare her feelings.

I know this doesn't fit your question, since it is non-hardy here, but I do grow an evening-scented jasmine. I got it from Dena and Wild Bill about 5 years ago (or more!) and have - amazingly - successfully overwintered it indoors all those years. I do love that plant - how can you not, with that fragrance?

I also tried yucca one year. I had a few variegated (Gold Swords) in pots on my patio for winter interest. For some reason they looked gorgeous throughout the winter and promptly died in late spring. Never did figure out why and never tried them again.

I just might have to consider a camellia. I just organized a talk last night at my library where the owner of a local nursery spoke, and he was praising camellia (wish I could remember the one he discussed). Between that and the photo above, I think it's an omen....

:)

RE: Anyone else growing or planning to grow exotics?

Dee,

I'm growing Jasminum officinale outdoors. It's gone through three winters with varied degrees of success. It keeps coming back, but only thrived and bloomed one year.

As for those yuccas that died, I wonder if it's because they were in pots? They should be hardy in the ground.

Take a look at the Camellia Forest Nursery web site (www.camforest.com). They have a great selection of hardy camellias.


 o
PM2 - if you'd like to see a few pictures......

PM2,

I had posted some photos of my indoor plants on Jan. 4 ("A sunroom break from snow and cold!"). Most of them go out for the summer.

I also posted quite a few photos on Sept. 9 ("Some photos of my flowers") which is a collection of blooms at various times of the year.

I will try to get some of the English garden photos together next week.

RE: Anyone else growing or planning to grow exotics?

Thanks Bill, there's no rush, take your time. It's a long winter. :-)


 o
RE: Anyone else growing or planning to grow exotics?

Why, Bill, you enabler, you, lol! Do I dare take a look at Camellia Forest Nursery...?

I wondered the same thing about the yuccas. I had them in pots for two reasons. First, when you look out my back window, you see the brick patio and a large expanse of black asphalt driveway/parking area. In summer, not so bad because of the backdrop of trees, as well as many contaiers on the patio. In winter - blah! So I wanted some winter interest and put some redtwig dogwoods, junipers, and the variegated yucca in pots. It really did look nice throughout the winter.

Secondly, I've read that yuccas can become overly aggressive, so I hesitate to put them in the ground. What has your experience with this been, Bill?

Thanks,
Dee


 o
RE: Anyone else growing or planning to grow exotics?

Dee,
In my opinion yuccas are not at all aggressive. I've had a clump of Y. filamentosa (the common one we all see everywhere) that was given to my by my grandfather over 50 years ago! It's thriving and has never been killed back or anything like that, so let's assume normal growth. It's formed a clump maybe 3 ft. x 5 ft.? It has about 4 crowns and some of them bloom every year. Some of the old ones die off and new ones sprout. And I've never seen a single seedling sprout. I'd say that's pretty well behaved!

As for CamForest..........go for it!


 o
RE: Anyone else growing or planning to grow exotics?

I've always had an interest in cacti but only recently found some can be grown here in CT (Some how managed to miss the fact that prickly pear are native despite having lived here all my life), and now have an outdoor garden that I experiment with.

With a little luck you may even get a flower or 2

RE: Anyone else growing or planning to grow exotics?

Ray,
I've had prickly pear for years. It's almost a weed but not. It's a patch about 6 feet x 4 feet and opens hundreds of flowers each year. But I'm hoping to prepare an area for more kinds of cactus. I also have some yuccas, ice plants sempervivums and sedums.

Your garden looks good!

RE: Anyone else growing or planning to grow exotics?

Very different, I love the blooms on them! I take it these are all hardy? I bet the squirrels don't bother your plants. [g]


 o
RE: Anyone else growing or planning to grow exotics?

Get out! I never knew prickly pear were native to CT! Wow, that is really interesting. You're right, PM2 - I bet the critters leave it alone, lol!

Thanks for that info on the yuccas, Bill. Maybe I will try some in the ground. Still haven't looked at the Forest Farm link yet, lol - I'm still debating with myself! Maybe I'll spend the evening doing a bit of browsing there....

RE: Anyone else growing or planning to grow exotics?

Okay, I didn't learn my lesson last year when my garden was wiped out by slugs so this year I decided to try to do some different plants ...exotic? I have no clue but hard to grow yes! LOL I've planted about 100 black mondo grass seeds, guinea hen flowers (which I learned can take 6 monts to germinate) toad lillies, and a weeping snow fountain cherry tree ... I spent the last three months searching the web for uncommon plants, tired of seeing the same thing in all my neighbors yards, Now lets see if I can keep the darned slugs and wildlife from eating them all!!!


 o
RE: Anyone else growing or planning to grow exotics?

Slugs................yeccch! Salt shaker and flashlight at midnight.........in my robe and slippers. Nothing more to say! LOL!


 o
RE: Anyone else growing or planning to grow exotics?

Cat....I think I stick to tried and true entirely too much. I think I should be trying to find something a little different to grow like you and Bill. I've never heard of guinea hen flowers. I do like toad lilies but I tried one and it didn't make it through my winter. I hope you will post photos later.

Bill...I never saw a slug in my yard until last year. We had a lot of rain that wouldn't let up and they started showing up. Where do they come from, out of nowhere? [g] You remind me of me... when I can't sleep in the summer, I will get up and go out in my pjs with the flashlight and a paper cup and look for earwigs, which I hate! They seem to love me for some reason. Just the same I enjoy being out there at that hour. You get to see all the night creatures and some of the fragrant plants make the trip worth it. And if there is a moon out, a warm breeze and it's very quiet, it's almost magical! And you can't see all your mistakes at night. [g]


 o
RE: Anyone else growing or planning to grow exotics?

Slugs do seem to just appear. They like smooth surfaces, so certain mulches may be a slight deterrent. You won't see them on a sunny day unless you overturn some wood or something that's on the ground, or if you have some stacked pots which they seem to like or some other damp, dark and cool place. If it's been raining then they'll come out. I've also been seeing a lot of snails in the past several years, and it had been a long time since I'd seen those. It's like my flower border is a salad bar!


 o
RE: Anyone else growing or planning to grow exotics?

I wonder if there are any natural predators for snails and slugs? What about chickens or ducks?


 o
RE: Anyone else growing or planning to grow exotics?

I had actually placed an order for a few ducklings online and then found out that my town zoning forbids it, and I would hate to have a cute little quacker around and then have to give him away :( maybe I can attract some toads or snakes into my garden to snack on them? I'll post the photos of what survives my black thumb this year LOL LOL but I'm learning little by little. At least this year I'm prepared for war, last year I may as well as worn a chef's hat as I was planting for the little slimeballs...


 o
RE: Anyone else growing or planning to grow exotics?

Yes but they can do a lot of damage to the plants as well. Frogs are probably best if you have a place for them to stay during the day (they're mostly nocturnal) and to hibernate in winter.


 o
RE: Anyone else growing or planning to grow exotics?

In our town, they will allow chickens if they are hens and not roosters and limit you to a small number, I forget how many. We don't eat enough eggs at our house to justify having them and I could never bring myself to make a meal of them. [g] I understand the hens can really do damage in the garden too, but that ducks may be easier on the plants. The only person I know with chickens in a suburban area, has a small chicken coop and has them penned in. Unless you let them out to browse your gardens I guess they wouldn't be very good at insect control.


 o
RE: Anyone else growing or planning to grow exotics?

Bill, Yes indeed I can see where the prickly pear can be almost a weed, really likes our weather.
I had found it in with the 'regular' perennials at a local nursery and that sparked my interest.

A little research and I found quite a few other Opuntias
that potentially survive and a few other varieties. A few bags of gravel and sand in a very well draining raised bed and they seem quite happy. I think I have a little over a dozen different plants now, mostly Opuntias.

I did have some sort of critter 'sample' one of them once last year, beyond the spines Opuntias have surprise for intruders in the soft looking hairs on them. Glochids, barbed almost invisible things that likely left the critter with a sour mouth for at least a few days.

Slugs do like munch also on cactus.


 o
RE: Anyone else growing or planning to grow exotics?

Ray,
Now and then there are some holes in a few pads, I imagine from slugs, but only on the new growth. Once they harden and have the spiny glochids, they seem pretty untouchable. The growth rate is so fast that they don't succumb to a few bites taken out of them anyway.

Bill


 o
RE: Anyone else growing or planning to grow exotics?

snows gone off the unprotected cactus garden now. Did a quick check and I think I have 20 or so different specimens. Looks like one didn't like our winter and will likely not make it (Opuntia Ellisiana). Not a problem as I expect some to succumb to wetness. Next month April 10th and 11th the Connecticut cactus and succulent society will be having their show and sale in Waterbury and I'll see what else may interest me at John Spains cold hardy table. http://www.ctcactusclub.com/
