Just like H. virginianum, H. canadense is also rarely cultivated. It has the same curled flower buds with ciliate calyces, which resemble an exquisite lace work; however, the leaves are simple, large, sometimes with wide lobes; also spotted in early spring.
Recognized by pollination ecologists as a very valuable species because it attracts a large numbers of native bees; the flowers are often foraged, long after their prime, by bumblebees. Useful as a groundcover in difficult shady areas and for naturalization projects.
The population in the image was growing at the edge of a deciduous forest in part-shade, in quite a dry location (Ontario, Canada). Not very often seen, actually quite rare. In quite a few U.S. states is listed as extremely rare or threatened.
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.
