Aubrieta deltoidea (Purple Rockcress) is a low-growing, mat-forming perennial plant native to Europe and Asia. It typically grows up to 6 inches (15 cm) tall and spreads up to 2 feet (60 cm) wide. The plant has a dense, creeping habit, with numerous woody stems that are covered in small, dark green, evergreen leaves.
The leaves of Purple Rockcress are small, oval-shaped, and arranged in a rosette pattern. They are typically 0.5 to 1 inch (1.3 to 2.5 cm) long and 0.2 to 0.5 inches (0.5 to 1.3 cm) wide. The leaves are smooth and shiny, with slightly toothed edges.
The flowers of Purple Rockcress are produced in clusters at the end of the stems, with each cluster containing numerous small, four-petaled flowers. The flowers are typically deep purple in color, although some varieties may have pink or white flowers. They bloom in early to mid-spring, and are an important nectar source for bees and other pollinators.
After the flowers have bloomed, Purple Rockcress produces small, dry fruits called capsules, which contain several small seeds. The plant is adaptable to a range of soil types and prefers full sun to partial shade.
Purple Rockcress is commonly used as a groundcover in rock gardens, borders, and other landscaping applications. It is also suitable for planting in crevices and other areas where other plants may struggle to grow. The plant is drought-tolerant and low-maintenance, making it a popular choice for gardeners who want to create a low-maintenance, natural-looking landscape.
