Noccaea rotundifolia, commonly known as Round-leaved Pennycress, is a hardy annual herb native to alpine and subalpine zones in Europe, including the Pyrenees, Alps, and Carpathians. It is adapted to survive in harsh, cold environments, such as arctic conditions and high mountain habitats. This plant typically grows to a height of 10-30 cm and forms a basal rosette of leaves with short, unbranched stems that culminate in dense racemes of small, showy pink flowers that bloom in late spring to early summer.

Round-leaved Pennycress is valued for its ability to thrive in rocky, well-drained soils and its low maintenance requirements, making it an excellent choice for rock gardens and alpine collections. It prefers full sun to partial shade and requires moderate water, particularly in well-drained, loamy or sandy soils. While it is not commonly used in large-scale cultivation, its resilience and attractive flowers make it a charming addition to specialized garden settings. Its small stature and flowering habit also make it suitable for container gardening. Potential problems include susceptibility to common pests and diseases that affect Brassicaceae family members, such as flea beetles and downy mildew.CC BY-SA 4.0
