This(to my eyes)is the most beautiful Cycad out there!
Truly prehistoric looking!

Here are some of the best pics I have come across,
they just happen to be on E-bay.
Scroll down a little and check out all the pics-
especially the leaf structure in the last 2 pics!
I will post a pic of mine later.

WARNING-these are"pricey"(-;

Here is a link that might be useful: E.horridus

Hey jim I have one. Its got a few leaves on it. Loves the sun hates the cold. I got it last year its send up one leaf now. I have lots of cycads.


 o
RE: Anyone growing Encephalartos horridus?

Nice Mike
Forgot your into Cycads,post a pic of it if it's not to much trouble.
I will do the same.
I here once the caudex gets a little size they pick up speed.
Where did you get yours,what was the price like?

Wow, thats a very nice cycad. I got to see if I could find a nice one for a good price!

Good luck!

RE: Anyone growing Encephalartos horridus?

There are several forms out there. My favorite is from the Hewson collection, where the leaflets have an exceptional 3-D twist. There is also a Dwarf Form, and some with flat leaflets looking very much like E. trispinosus.

There are also many hybrids with other species.

The biggest challenge for us "northerners" is keeping the lovely blue wax intact. First of all, while the new leaves are flushing and forming the hard wax deposits, it is best to provide maximum sun without any rain getting on the leaves. Once the leaves have hardened completely, they are more resistant to rain and keep the blue color but spots will form.

RE: Anyone growing Encephalartos horridus?

That is a real beauty!
In the eye of the beholder of course.(-;

I could see how some may not like this one
but enough about them!

I hear the name Horridus means horrible,which would
accurately describe a close encounter with one of these!

That's a real nice specimen-you must be very proud!

Thanks for posting this pic


 o
RE: Anyone growing Encephalartos horridus?

Horridus (latin) and horrible (english) are cognates (look similar, same meaning). The verb form in latin is horrere or to dread in english. If they are as sharp as they look, I would have to agree with whomever named this plant. I think its a nice plant because of how uncommon it is, but I think only collectors would agree. It seems like a hard plant to take care of, but xerophyte, you really have a very beautiful, healthy one! What do you do to keep it looking so nice!

Good luck!
-Alex


 o
RE: Anyone growing Encephalartos horridus?

I treat it exactly the same as my other Cycads, except that during a newly emerging flush I stick it in my greenhouse or move it under shelter during rain to keep the leaves dry so that they retain the heavy wax that is responsible for the blue hue.

It is a vicious looking plant but it is not that big. My Macrozamia moorei has inflicted much more poking damage.

Sometimes this plant stands out a bit more impressively in the landscape than in a pot. One of my favorites, too

I love the look of Cycads,when you have alot of them like in the last picture,it reminds me of what the planet would have looked like during the jurassic period.I have two 15 gallon Cycas revolutas,sadley they wont live here planted in the ground.What is the most cold hardy cycad?Everyone says cycas revoluta is but I found one in a catalog I get and it says it's cold hardy to my zone,it's Cycas taitungensis.Is this the most cold hardy cycad?In the picture it shows it looks like a cycas revoluta.There is one that looks like cycas revoluta,but with blue fronds.I found it on some website, it also said it was the most cold hardy, but I cant find it again.Just what is the most cold hardy cycad?Does anyone know the name of that blue colored one im talking about?Love that last picture!!


 o
RE: Anyone growing Encephalartos horridus?

I think Encephalartos would look really fantastic in a desert like landscape, something like what you would find in a very nice yard in california. I wonder if they can handle places like Florida since they get a lot of rain.
Butiaman...
I think the blue cycad your talking about is Cycas panzhihuaensis. It is the most cold tolerant cycad (also has blue leaves), but not much more cold tolerant than C. taitungensis. one major downside is that it grows very slowly so when it loses its leaves every winter, it will take a while to replace them. I would probably go with C. taitungensis since its faster (actually faster than C. revolutas. The trunk is cold tolerant to about 10F and the leaves maybe to 20F-25F. It might need some protection during the coldest nights and I would protect it when temps go below 20F just to be safe, but its easy to protect since by then all the leaves would have died off.
Good luck!

Thanks Alex,I use to have 3 C.revolutas planted in my yard.They dident loose there leaves till temps. droped below 15F.The trunks died at 10F,I use to check them everyday because I knew they were not suppost to survive in my zone.I was looking for the blue one because I like to mix different colored plants together,(leaves not flowers)and blue is a rare color in most plants,I love the blue Med.fan palms I have,they really stand out.I really like cycads but some are very expensive,and they for the most part like drier and warmer zones than mine.Thanks again.


 o
RE: Anyone growing Encephalartos horridus?

Some of the Dioons also exhibit excellent cold tolerance.

Alex: the blue Encephalartos grow OK in Florida, although they don't achieve the same "blue" because of the rain/ humidity. They also do not cone nearly as easily as in SoCal.

Glad I helped. I also like to mix lots of different types of foliage together including different colors.

Thanks for the info on that. Too bad they dont get that nice blue color in moist places.

Nice cycads! They are all looking healthy.

Good luck!

RE: Anyone growing Encephalartos horridus?

Shame on me - I don't have any pictures of the E horridus in flush :-(

I really should have better photos of my Cycads in growth. Here are some that I do have:

E whitelockii
Encephalartos whitelockii, very furry young leaves, they will eventually be HUGE

C rumphii C rumphii C rumphii C rumphii
Cycas rumphii, from the beginning of a flush all the way until the end. A lovely and easy to grow specimen.

C revoluta C revoluta
Cycas revoluta, showing the lime-green new flush not yet hardened, and a further shot with the old leaves removed.

M moorei

Macrozamia moorei, another easy plant but not so easy to find in a large size. I was lucky to get mine some years back when a shipment into the US was supposedly confiscated and then made available.

E horridus

This is another view of my E horridus. I haven't had a new flush for 2 seasons now because each of the last 2 years I transplanted into a new pot. It is normal for Cycads to postpone growth for one season as a result of transplant shock.

E arenarius
New flush on Encephalartos arenarius

E altensteinii x arenarius E altensteinii x arenarius E altensteinii x arenarius
Here is new growth on an E altensteinii x arenarius hybrid

Somehow I have no photos of my E whitelockii in full spread, nor of my E longifolius 'Joubertina Gray Form'. I also have a nice Dioon mejiae but i chopped back it's leaves because they were damaged last season, and an E horridus 'Dwarf Form' that also had a leaf pruning.

I have a seedling E lehmanii 'Kirkwood Form' that is nothing special so far, and a small C thouarsii.

I promise to take new and better photos of all the new growth this season.

Wow-those are ginormous,that Horridus couldn't be any healthier! ~is that even a word?-LOL

T7-
You might have to sell your car with the price of some of these-they are super rare!
If you do decide to get any of the above varieties,check around,there are people charging the same price for drastically different sized plants!


 o
RE: Anyone growing Encephalartos horridus?

I agree Jimhardy, some sellers take advantage of impulse shoppers. There are decent deals to be had from reputable nurseries. But Cycads will always be expensive due to their slow growth and rarity.

If I must make one recommendation, it would be to try to get the biggest plant you can afford. In my experience, seedlings and small plants in the 1-3 gallon size grow very slowly and take a long time to recover from mail-order transplant shock. They also have a greater tendency to rot since they need very deep pots and are probably not being given adequate root room in standard pots. Most Cycads, especially Encephalartos, have deep tap roots. Young seedling plants need a 5-gal standard pot at least, but that is too much soil volume to try and maintain moisture control. Cycad nurseries utilize special long tom pots.

There are even some Australian Cycas species that refuse to grow unless the roots reach a certain depth.

Cycas revoluta is one of the few Cycads that tolerates shallow pots and root pruning. Anyone can grow these well. But some of the rarer Encephs are a different story.

Even though larger plants will easily fetch 100's of dollars, it is worth it for an established plant that flushes full sets of leaves and will grow very well for many many years.

x


 o
RE: Anyone growing Encephalartos horridus?

I agree,really need to look and communicate with "some"of these sellers.

Next on my list is Encephalartos Princeps,another rare and PRICEY Cycad
but beautiful as can be without all the catchy sharp angles of Horridus (-;


 o
RE: Anyone growing Encephalartos horridus?

You will get more bang for the buck with E. lehmanii, which to the untrained eye looks identical to princeps and many other similar species, except it is not nearly as rare and is less expensive.

x


 o
RE: Anyone growing Encephalartos horridus?

I think in going to keep from buying rare cycads until I get the chance to get them cheaper farther south. I think its too expensive to get larger, rarer ones from nursuries online. Some are much more than they are worth which like you said, is still a lot when you are talking about there rare cycads. I would be willing to spend a good amount of money for the nicer rare ones.

Good luck! Hope this cold isnt bothering your more exotic cycads. 39F here according to a local weather station but 46F according to my yard thermometer. I had to take in my breadfruit. But summer will be here soon!
-Alex


 o
RE: Anyone growing Encephalartos horridus?

Frosts are no problem, let alone sub-40F. There are no new leaves forming so I just leave everything outside. They have been there since late March.

Another advantage to buying at a nursery vs. mail order is you get to pick what you want, and you can avoid major root disturbance.

However, for the blue species, you will have to go to Cali to pick up anything decent. I doubt there are too may Florida nurseries growing the blue Encephs since they don't look as good with the oppressive heat, humidity and rain.

x


 o
RE: Anyone growing Encephalartos horridus?

I have found one grower out in Cali which I don't want to share right now but I will.
His prices are better than the others and his plants are bigger,he is also VERY reasonable on shipping.
This guy also has all the ones I am interested in!

X-
E. lehmanii is on the list also,it can sit next to my E.princeps(-;

I just piked up a 5' Dioon spinulosum with an 8"caudex for $40!


 o
RE: Anyone growing Encephalartos horridus?

Hopefully I will get the chance to get some in Cali. It definitely seems like they have all the rare cycads.

Good luck!
-Alex


 o
RE: Anyone growing Encephalartos horridus?

Here are more blue cycads from California (not sure how many photos I can upload at once, so bear with me). First one is Encephalartos lehmannii, then E princeps, and lastly, a rare Encephalartos arenarius (right side of photo) next to some 'normal' E arenarius (left)

Encephalartos princeps

Enecphalartos arenaius normal and blue


 o
RE: Anyone growing Encephalartos horridus?

To anyone still reading this thread, who is interested in Cycads but doesn't know which one to get...Cycas thouarsii grows pretty quickly, eventually grows large leaves that are soft (not thick, firm and sharp like others) and is not fussy about needing full sun. It is readily available and can be had for a very reasonable price. They probably have more of a tropical look with the gracefully arching multipinnate leaves, than many other species. They grow beautifully outdoors during the warmer months, and then in the house during the winter they do just fine in a dark corner as long as watering is minimal.

It would make an excellent "beginner" plant. Large well grown specimens are beautiful. Cycas rumphii and Cycas circinalis are very similar in appearance and culture.

 o
RE: Anyone growing Encephalartos horridus?

Wow
Those are great pics-thanks for posting them.


X-
That is a nice one,you gotta love almost anything that comes
out of Madagascar.
40 leaves at a time,6-10'long would be a lot of fun,especially since it is one of the fastest growing!
Anything this beautiful that grows this fast is a winner.


 o
RE: Anyone growing Encephalartos horridus?

Those are some very nice pics. I really like the color and leaf structure of them. They must be very well cared for.
Xerophyte, I am going to get some more info on the cycads you mentioned.

Did you notice the Staghorn(?)fern in the last picture?


 o
RE: Anyone growing Encephalartos horridus?

No didnt notice it! Good find! Thanks for pointing it out. It looks really great and huge. Its probably a different species than mine (definitely a staghorn fern though) but I would love for mine to get to a size like that some day. After some burn from the heat in april, I think my staghorns are enjoying the weather recently. Its starting to put out lots of good growth after that humidity and heat last week but this week has been extremely cold. Low temp in my yard was 41.5F this morning and its only 53F outside now. Definitely feels more like late march-early april than early may!

Thanks again for pointing that out. Good luck!

 o
RE: Anyone growing Encephalartos horridus?

Yea and a lot of low humidity and days with dry winds have
burned some of my ferns etc this year.
Never thought I'd say it but bring on the heat/warmth and humidity! (-:

 o
RE: Anyone growing Encephalartos horridus?

It looks very healthy and off to a great start! Not sure if these are very fast growing cycads, but in a few years, its going to really catch a persons attention! I think you are probably the only person in Iowa with an Encephalartos horridus so thats must be a pretty good feeling (too bad the name doesnt sound as pleasant!)

Good luck!
-Alex


 o
RE: Anyone growing Encephalartos horridus?

If "in a few years" you mean 10, then yes, LOL.

It takes time to get seedling cycads out of the juvenile stage. When the caudex starts to thicken, leaves get bigger and increase in number. In the beginning growth is slow. That's why bigger plants are pricey.

Have fun with your plant! I'm assuming it is new, right? Mail order? Don't be alarmed if there is no new growth until next year or even the year after. Transplant shock takes time to recover from. Be careful not to overwater since the formation of new roots is also slow. When you potted it up, did the roots hit the bottom of the pot? These guys have deep tap roots and may suffer if not allowed to grow that way.
