Officinalis - Comfrey
This species, common in undergrowth, produces small clusters of white, pink or purplish flowers in spring. Known since antiquity for its medicinal properties and garden applications, it is particularly popular with gardeners who love fermented extracts.
Sow in trays or pots in clusters of 4 or 5 seeds. Keep substrate moist until seedlings reach the stage of 3 or 4 true leaves. Then transplant directly into place. Propagation by stump division also works well.
Extremely hardy, comfrey will adapt just about anywhere. It can withstand temperatures down to -30°.
