Arisaema sikokianum - plant & flowers

Photo by Mark McDonough

The Japanese Arisaema sikokianum is one of the best
and showiest species of hardy Arisaema, easily
grown in New England, USDA Zone 5.

The plants are sturdy, standing up well to wind and
rain, making a good show in the garden.  The foliage
has a strong likeness to the American species
A. triphyllum, including similar venation and a
3-part leaf on younger leaves. With sikokianum,
the foliage is thicker and more leathery, on mature
leaves producing a sub-leaflet at the base of
each side leaflet, for a total of 5 leaflets.
