Brassica kaber, commonly known as wild mustard or charlock, is an annual wildflower that grows 1-3 feet tall with bright yellow flowers. It blooms from May through July and thrives in full sun with minimal water once established. This plant readily self-seeds and can spread quickly in favorable conditions.
In an HOA neighborhood
Canola takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.

Wildlife value
The bright yellow flowers attract bees and beetles during the spring and summer months. Seeds provide food for birds later in the season.
