I'm hoping you experts will blow this plant's cover too fast to make posting

a picture to the Utrecht ID site worthwhile; but I'd be happy to post there,

too; am not snubbing Utretcht. 8-)


This Arisaema was received several years ago as A. uralense

(which seems not to exist). It rapidly forms clumps. It looks a lot like

Arisaema triphyllum. Its pseudostem seems exceptionally thick, however, and

in Zone 8 it flowers in March-April, rather than in May-June. It has already

breached the ground.

Re Barry's ID as A. amurense, it's difficult to tell from the photo, but if
it looks like A. triphyllum, I assume that the plants all have 3 leaflets.
Wouldn't that seem to make amurense less likely, unless some forms have only
3 leaflets?
