Another North American woodland plant that is rarely cultivated. The conspicuously silver-marked, pinnate leaves appear early in the spring and are followed by curled flower buds with ciliate calyces which resemble an exquisite lace work; opening to reveal white or purple bell-shaped flowers with exerted stamens.
It is recognized by pollination ecologists as s very valuable species because they attract large numbers of native bees; the flowers are often foraged by the bumblebees long after their prime.
Useful as a groundcover in difficult shady areas and for naturalization projects. It is considered a bit weedy but still not capable to compete with non-native invasive species. To control its potential undesired spread, one option is to mow it over after flowering so it won’t set seeds.
best if sown in the fall outdoors; or in the spring after cold-moist stratification.
Update: deep simple epicotyl dormancy – meaning that the root will emerge in late fall after a warm stratification (2- 3 months) and the shoots growth will begin in the following spring (after cold stratification). If the sowing is done late in the fall, the warm period will complete next summer and shoot growth will happen only in the second spring after sowing.
