Growing Davidson’s Rockcress Successfully

- Water regularly the first season to help establishment
Ongoing Care
Once established, Davidson’s rockcress is refreshingly low-maintenance. Water deeply but infrequently during prolonged dry spells, and resist the urge to fertilize – these plants prefer lean conditions. You might want to deadhead spent flowers to encourage more blooms, but it’s not strictly necessary.
Supporting Local Wildlife
By choosing Davidson’s rockcress, you’re not just adding beauty to your garden – you’re creating habitat. The spring flowers provide nectar for native bees and other small pollinators, while the plant’s structure offers shelter for beneficial insects throughout the growing season.
