I just came along this picture
one of my favourites Arisaema kiushianum
Tomorrow I harvest the corms

And what a beautiful plant (and photo) to start this thread with. 

Does this species tend to produce multiple cormlets?

[McDonough]

Just like I said on your Facebook posting of the same image "hoot hoot".   The flowers look just like a little owl.

[bulborum]

Yes Rick
They produce normally enough cormlets
I can send you some if you like
They will be harvested later on the day

Yes mark a beauty
but I find it difficult to photograph
This is one of the 34 pictures I took
before I was satisfied

WOW
What a spot

Gene, delighting sight 

Bulborum, an new unknown Arisaema for me ! The big red Allium I got from you at St Jean de Beauregard Plant Fair grows well but what is its name please ?

[bulborum]

I PM you

[McDonough]

Gene, that's a mighty impressive colony, like a gaggle of geese.  Did you grow these from seed?  Your climate is more advanced than mine, my plants just broke ground a couple days ago.

Arisaema sikokianum, grown from seed:

When growing these from seed how many years to bloom? I have quite a number of seedlings now that were sown 2-3 years ago.

Amy: I don't know how long it takes from seed for many Arisaema species, but I have been getting seed from the Arisaema Enthusiast Group, and have been pushing the seedlings along. As soon as they go dormant, I unpot them, and place the tuberlets in a ziplock plastic bag, and they go into the fridge for 2 to 3 months. This lets me start them into growth at least twice per year. With plenty of feeding, it is possible to cut a year or more off the time to first bloom. I am hoping to speed up the growth of several other species this way (ciliatum var liubaense, consanguineum with silvered foliage, fargesii, heterophyllum, jaquemontii, serratum, sikokianum, and tortuosum).Now if only the new seeds would arrive for this season's effort (candidissimum, costatum, and limbatum).

[RickR]

So Gordon, then some of the growth cycles of your seedlings are completely under artificial lights?

[Gene Mirro]

My A. sikokianum are all grown from various seed lots.  They are pretty slow.  You might get a couple of blooms in three years, but most will bloom in four years.  But you have to keep them growing strongly without stressing them.  My plants get full sun for several hours around midday, then some shade in the late afternoon, which is the hottest part of the day.  If you crowd them, they will survive, but they may not bloom or develop well.

Rick: Wish it were so! I've been growing them in a window if the weather is too cold to use the unheated greenhouse. My first try with pushing them along involved A. consanguineum. The newly sprouted seedlings went dormant quickly, so I had tuberlets about the size of a pea. I re-started them into growth in the house a bit too early and had thin attenuated growth.... but still growth in late winter. They went dormant in spring and I got them going again for the latter part of summer (this time in the greenhouse). All but two of them are already up (southeast window of the house). I started them up a few months ago, as the days were getting longer, and made sure to rotate the pots once they had emerged. The new growth is now complete, totally vertical, and self supporting. I think a few of these nay get to blooming size before this growth cycle is done.
