Botanical Description of Canadian Fleabane:

Considered a weed rather than a herb, Canadian fleabane is an erect annual that grows to 2.2 metres tall. The stem rises from a clump of basal leaves that wilt later and alternate lance-shaped, dark green leaves have coarse white hairs, and margins that are occasionally toothed. Numerous tiny daisy-like white flowers appear throughout the year.


History of Canadian Fleabane:

The American Indians introduced the herb’s medicinal virtues to the early settlers of the New World who spread the word about its benefits. Herbalist to King Charles 1 of England, John Parkinson, heard about the medicinal uses of the herb and in 1640 described it as a species of America. Interestingly, the herb was found growing in the botanical gardens of Paris in 1653. The only way fleabane’s presence could be explained was that it was introduced to the gardens by seeds that were attached to stuffed birds or beaver skins.
