Anemonella (Ranunculaceae). A. thalictroides germination has been very low despite the fact that this species is native on the property. The only germinations so far were from two samples of fresh seed in 70D-40-70L(3% in 3rd w) and 40-70D- 40-70D(3% in 3rd w). The cotyledons develop within a week of germination, and the seedlings developed normally. DS seed immediately rots on contacting moisture and is dead. Outdoor treatment and GA-3 need to be tried.
