Excellent multiplier here in zone4a. Prolific bloomer.
This has been a wonderful plant for me. It blooms throughout the summer in morning sun and bright shade areas. The orange calyces and yellow flowers against the almost-black leaves really brighten up a shady area. The hummingbirds like to visit the flowers too. It isn't hardy here in Zone 7b, but it goes dormant when temperatures get low in the fall and the tuber is easy to overwinter inside. I just tried water rooting a cutting from a broken stem and it developed roots easily. I also just noticed tiny tubers developing at the base of the leaf petioles on the mother plant.
My Climate:
USDA Zone 7b
AHS Heat Zone 7/8
Humid
