Wood Betony – Pedicularis canadensis Quick Guide

Growing and Caring for Plants

Wood betony, Pedicularis canadensis, is a valuable and attractive native flower that is an indicator of pristine prairies. Its roots attach to the roots of nearby plants and uptake nutrients. Therefore, 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.

Medicinal Uses

Pedicularis Canadensis leaves and roots have a number of uses. They 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. 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).

It has been used in prairie lands to control the domination of aggressive tall-grasses.
