Re: Arisaema 2011
I quote Todd, my Arisaemas will not show for a while - if they have survived the severe freezing of the soil this winter :(
Last winter I lost 4 pots with great seedlings, they froze in my greenhouse :'(
Re: Arisaema 2011
Arisaema sikokianum, seed received from eBay vendor, sown 2/13/07:
Growing with Dicentra formosa, Corydalis sempervirens, and viola.
Re: Arisaema 2011
@Wim - A. engleri looks most interesting; I like the wide and open spathe; somewhat like A. sikokianum.
@Gene - Nice A. sikokianum; I'm curious about how much the seed cost on eBay.
Posted is a photo of 3 A. sikokianum, the two more mature plants always face each other each year, as if having a conversation. I find this aspect interesting, that the blooms seem to definitely be oriented a certain fixed direction from the tuber. I've never tried digging up a tuber and replanting it after rotating the tuber 180 degrees, to see if one can control which direction these flowers face.

Mark,
it was once included in A. sikokianum so it's very similar indeed. I even got this one as A. sikokianum

I've noticed this from other Arisaema's too, especially A. candidissimum which always seems to face away from the path in my garden where they are planted (even after I replanted them), so you had to trample through the other plants to see their face. Maybe they have an individual internal compass?
Re: Arisaema 2011
I have Arisaema intermedium seedlings in a pot. They were planted in January, came up in June and are still growing strongly with roots showing beneath the pot.
I have not grown Arisaema from seed before and suspect they are not like other bulbs. What is the next step? Should I repot them now? Do they need complete frost protection or can I just stick them in the bulb frame?
Any advice would be appreciated.
Re: Arisaema 2011
I have not grown A intermedium from seed before but other species. Last winter I lost several potfulls of seedlings as the pots froze in the very cold weather we had. Those I had planted out (Emptied the pot as one clump when they were growing strongly) and planted deep survived fine.
If I grow them on in pots I repot in winter/early spring when they are completely died down. The corms are like peas or small nuts in size and without roots and easy to handle.
Re: Arisaema 2011
Thanks Trond:
That is very helpful. I guess a key characteristic of Arisaema bulbs is that they are winter dormant and most other bulbs are summer dormant.
Re: Arisaema 2011
Hi David,
I've never grown A. intermedium from seed either, but I've grown a lot of other Arisaema species from seed. When I sow Arisaema I normally leave the seedlings in the same pot for 2 or 3 years (by that time you'll have much bigger bulbs which are easier to spot and transplant). Make sure to feed them a little during their growing period in the second year (if you leave them in the seedpot). When you're ready to transplant them, make sure they are in rest, like Hoy said. It's easier and better to transplant them when they aren't in growth.
Also, I've always put them in an unheated greenhouse during the winter and kept the soil reasonably dry.
Re: Arisaema 2011
A few in bloom here
A.ringens
A.tiwanense
A.ciliatum
A.speciosum
and full of promise A.exappendiculatum which i find is a bit too vigorous in the garden with its strong stolons .
Cheers Dave.
Re: Arisaema 2011
Wow! :o Love those Jacks!! Esp. the taiwanense with the long 'cilia' at the tips of each leaf part. Very cool. How hardy are these varieties? I have the ringens as overwintering seedlings in pots coming into their 3rd year so I'm hoping perhaps to get a bloom this year?

Wouldn't mind if any Arisaema spread voluntarily in my garden ;) I am also trying to increase my stock of Arisaema by sowing. Have got seed from Chris Chadwell and they always sprout well.

A. ringens has been hardy for me here in Massachusetts (near the New Hampshire line), although I have lost this species and others due to mole digging. I also grow an unidentified Arisaema collected by Darrell Probst (I think China, or possibly Korea) that looks much like A. taiwanense, although without those wonderful long thready ends to the leaves.
Re: Arisaema 2011

Didn't mean to criticise your English - I find it quite naturally that someone find this flower beautiful like a mother find her child beautiful ;)
Re: Arisaema 2011
The flowers of Arisaema kiushianum are soooooo cute, and from the vantage point of looking straight on at the flowers, they look like a little owls.

You aren't the first Mark

Wow Wim...my Arisaema will not even show themselves until late June, let alone flower!
