Lewisia is a genus of flowering plants in the family Montiaceae, native to North America. These perennial plants are known for their vibrant, colorful flowers that bloom in spring and summer. They typically grow in rocky or alpine environments, thriving in well-drained soils and full sunlight. The leaves of Lewisia are often fleshy and rosette-shaped, providing a striking contrast to the delicate flowers. Some popular species include Lewisia cotyledon and Lewisia rediviva, both appreciated for their ornamental value in gardens. These plants are also drought-tolerant, making them suitable for xeriscaping and low-water gardens.
