A. undulatifolium

[Roy Herold]

Jim:

I planted your Arisaema undulatifolium seeds on September 9, 1996, and left
them outside until early November (after a few hard frosts). Nothing had
germinated, so I put them in my minimally heated greenhouse area (down to
25 deg F). When I finally got around to planting my own arisaema seeds in
mid-February, I brought them into the warmer greenhouse area and put them
on a heating pad that keeps the soil temp at approx 70 deg F. They put out
leaves within two weeks, and I think I have nearly 100% germination. Just
for reference, they have a single parted leaf.

Thanks for sharing them!
