Big Sagebrush

CAN BE FOUND IN:

Big Sagebrush

Artemisia tridentata 

Appearance

Big sagebrush is a tall green-grey shrub that grows up to two metres high. It has lots of branches and grey bark. The twigs are very hairy and the leaves have three teeth at the end. It has small yellow flowers on the ends of the twigs, and the entire shrub smells wonderful. 

Range & Habitat

Big sagebrush grows from southern B.C., especially in lower elevations, down through the Rocky Mountains in the US. It mostly grows in grasslands and poor soils. 

Reciprocal relationships

Big sagebrush can be thought of as a protector plant for many understory community members. These plants grow in dense shrubs, which, when fully grown, provide protection for more fragile understory plants. They contribute to ecosystem health through fostering diverse canopy structures and biodiversity.  

The flowers bloom in late summer, and they ripen into hairy seeds that spread by attaching themselves to passing animals. Cows and sheep often graze in areas where big sagebrush grows. As the animals eat the grasslands, big sagebrush expands into areas where no grass is left. There is much more big sagebrush growing in southern B.C. than there was before we had cattle and sheep grazing. The leaves and branches are used by Southern Interior First Nations to make a tea for colds, and burned to help air out a house.
