Rock on Blue Rock Cress is a low-growing groundcover known for its sheets of violet flower cascading over stone. Rock on Blue Rock Cress flowers in spring in shades of blue, and performs best in part sun to part shade with low watering once established. This groundcover matures to roughly 5-7 inches tall and 1-2 feet wide. It is ideal for rock gardens, path edges, and the spaces between stepping stones, offering low-maintenance cover and weed suppression. Once established it needs little attention, making Rock on Blue Rock Cress a dependable choice for Canadian gardens. It tolerates dry spells well once its roots are down.
