Wod Betony

Wood Betony

Botanical Name: Pedicularis canadensis

En français: La bétoine, l’épiaire officinale

Wood Betony is a valuable native flower that is an indicator of pristine prairies. Its’ roots attach to the roots of nearby plants and uptake nutrients. Thereby, wood betony parasitizes other plants, using them as a water and nutrient source. This parasitism helps reduce the vigor of the tall prairie plants.

Flowers are attractive to butterflies, birds and bees as well as some species of ants.

Pedicularis can be used to relax sore muscles such as shoulders, arms, and backs, although there are precautions to take. As it is a plant that uses nutrients from other plant roots (although this is not always the case, they can flourish without the use of other plant roots), this can create other types of toxins to form. If you are planning on using this plant for herbal remedies, just ensure that it is not planted near a toxic plant or grass (such as Arrowgrass).

Water: Moderate requirement for water, tolerates some drought.
