Arisaema 2012

[Zonedenial]

I obtained costatum as a small tuber; I've had it in the garden for about seven years. It blooms reliably now, but hasn't multiplied.

Some Arisaema sikokianum, grown from seed:

[Hoy]

Your Arisaemas are so early! here they are the last plants to emerge - often not till midsummer!

[Gene Mirro]

A. sikokianum is the earliest to bloom here, much earlier than triphyllum.

[RickR]

Same with me, Trond.  Usually the Asian types emerge in late June or July.  I don't have A. sikokianum.

[Saori]

Gene, that's quite a view! I think A. sikokianum is one of the most beautiful in this genus and you can't have too many of them!

I had only one sikokianum in my garden but I wanted to get some seeds, so I bought two more plants. Unfortunately, all my plants are still male and I have to wait till one of them turns female... But I found a very rare coloring of A. sikokianum!

One thing... My Arisaema kishidae is female right now but I only have one plant and don't have male plants to collect pollen from. Does anybody out there have this plant and if so wouldn't mind sharing some pollen with me? I will share some seeds later if I successfully harvest the fruits or I will trade some of the seeds I have right now. Please let me know!

[Hoy]

Seems I have to get hold of A. sikokianum!

[McDonough]

Saori, that color variant (a hybrid?) of A. sikokianum is awesome, beautifully presented photographs, I imagine them as Mr. & Mrs. Sikokianum  Please tell us, was that a spontaneous self-sown plant?  Is there a possibility that it hybridized with another Arisaema species?

Gene, I was starting to wonder about my A. sikokianum plants, as they're all facing west, but in your impressive colony, they're facing various directions, so it's probably just coincidence that my flowering plants are facing the same direction.

[Saori]

Mark, as far as I know, this is one of the variations of sikokianum. I found this one as a one-off in a group of more than 100. I believe that the nursery from which I bought it is growing only sikokianum and so I think that this is seed-grown, but I'm not sure. I should have asked... I saw a green version of sikokianum on some Japanese sites before (if you are interested, here is a good link: http://blogs.yahoo.co.jp/fu2ran/59116249.html) and, though I have only heard that it exists, there is also a red version of sikokianum. If my other sikokianum turns out to be female next year, I will use a pink sikokianum that I have to pollinate it, and hopefully I can take the F1 and cross it back again, so that I can hopefully create a pink sikokianum.

The two earliest arisaemas to bloom here are ternatipartitum (shown) and kishidae, which both open their "jacks" in early April before the leaves arise and tolerate temps below freezing after opening.

Some more to look for! I am always interested in early flowering plants. Are they woodlanders?

[Zonedenial]

Yup, and pretty easy ones; ternatipartitum in particular rapidly clumps up.

[Afloden]

A new one Literally.

[Hoy]

A new one Literally.

And that is new to science or to you? Very pretty!

[Afloden]

New to science apparently. It is in the Asperatum group, but it seems to lack the long flagelliforme apex. This is clavate almost and does not protrude from the spathe. It is also disjunct from the majority of that groups distribution. I cannot give out country information yet.
