More about this plant
Lilac Beardtongue is a fibrous-rooted perennial reported around 0.61 m tall, with relatively narrow toothed leaves. Species references place it in USDA zones 3-6 and in dry to medium-dry sand or gravel, in full to partial sun. VASCAN records the species in Manitoba and several western provinces, but the supplied evidence does not settle native versus introduced status within Manitoba. Flowering is reported from May through July in the cited source; that is bloom timing, not seed ripening.
