Perennial pepperweed was introduced to North America from Eurasia and is a deeply rooted perennial forb with waxy coated leaves and stems. This member of the Mustard family can grow up to two metres tall.

Perennial

Grows on well-drained, often saline sites in unshaded areas. This species can be very invasive and invades pastures, croplands, meadows, and riparian areas. Habitat quality in riparian areas can be seriously impacted. Croplands and pastures may have reduced yields and harvest will be contaminated by pepperweed seeds.

Perennial pepperweed reproduces by seed or by root fragments. Seed production is moderate, and seeds do not significantly bank in soil. Seeds are dispersed by wind and water and most often land close to the parent plant.

Currently only one recorded site in the southern part of the region on Highway 97 at 91 Mile.
