Smooth Rockcress

Smooth Rockcress (Braya glabella) requires water during its period of active growth, which is typically from late spring to early fall. Water thoroughly and deeply once each week. Allow the soil to dry out slightly between waterings; the plant should not be kept constantly wet. During periods when the plant is not actively growing or when temperatures are extreme (either cold or hot) reduce the amount of water you give to this plant. Water less often or provide just enough to keep the plant alive, but not enough to bring it out of dormancy.

Smooth Rockcress (Braya glabella) is a short-lived perennial plant. This species thrives in full sun, and prefers temperatures between 60 and 85 degrees Fahrenheit. It should be grown in slightly alkaline soils that are fast-draining and are kept moist but not waterlogged. For optimum growth, Smooth Rockcress requires direct sunlight for at least 6-8 hours per day. To ensure optimal performance, the plant should be grown in a south facing location with full exposure to the sun. During the hottest times of the day, the plant may benefit from some shade to help protect it from excessively hot temperatures. With sufficient sunlight and the proper environment, Smooth Rockcress will flower profusely in the summer months and may reach up to 8 inches in height.

Smooth rockcress (Braya glabella) should be pruned in early spring, after all frost has passed but before flowering occurs. Pruning should be moderate, removing no more than 1/3 of the plant’s growth, and should focus on dead or damaged foliage. Pruning should also be done to encourage air circulation around the plant, by thinning out areas of dense foliage. Pruning smooth rockcress in the spring will help promote healthy new growth and flowering.
