Arabis is a genus of flowering plants in the family Brassicaceae, commonly known as the mustard family. These plants are often found in rocky or alpine environments and are characterized by their small, white to pink flowers. They typically bloom in spring and are popular in gardens for their attractive appearance and ability to thrive in poor soil conditions. Many species of Arabis are also known as rock cress, and they are native to various regions, including Europe, Asia, and North America. These hardy perennials can be used in landscaping to create ground cover or to add color to rock gardens. Their resilience makes them a favorite among gardeners looking for low-maintenance plants.
