Hardy Arisaema for northern growers - compiled Now Arum sp?

[George R Stilwell, Jr.]

Better check with our new members Rob and Sheron Illingworth.

They live and grow Arisaema near Thunder Bay, Ontario, USDA 4,
Min -40C/-40F with snow
Min without snow -20C/-4F
Max 30C/86F, rarely higher
Frost free days 110 on average.

If that isn't cold enough for you, I have a skunk cabbage you could grow.

Incidentally, A. ringens often gets killed to the ground in spring here
(zone 7). Early warm weather followed by a freeze is worse than pure
cold.
