Summary
Boechera perennans, commonly known as Perennial Rockcress, is a deciduous perennial herb native to a variety of habitats including rocky slopes, open woodlands, and chaparral in the Southwestern United States and Mexico. It typically forms a clump of several erect stems that can reach over half a meter in height. The plant is characterized by its small, widely spaced flowers that are purple or pink-purple, blooming on long, thin stalks. These flowers are moderately showy and appear in the spring. After flowering, it produces siliques, which are long, very narrow seed pods that can be up to 6 centimeters long, adding to its ornamental interest.
Perennial Rockcress is valued for its drought tolerance and ability to thrive in poor soils, making it a suitable choice for xeriscaping and rock gardens. It is also used for naturalistic plantings and restoration projects. This rockcress prefers full sun to part shade and requires minimal water once established, making it easy to maintain. It is adapted to soils with fast drainage and is often found in challenging growing conditions in its native range.CC BY-SA 4.0
