Aurinia

Aurinia is a genus of flowering plants in the family Brassicaceae, commonly known as the rock cresses. These plants are native to the alpine regions of Europe and Asia. They are perennial herbs, typically forming dense cushions or mats of foliage. The leaves are usually small, narrow, and often covered in fine hairs.

The flowers of Aurinia species are typically yellow and borne in racemes or panicles. They bloom in late spring to early summer. The most well-known species is Aurinia saxatilis, also known as basket of gold or golden alyssum. This species is widely cultivated as an ornamental plant for its bright yellow flowers, which can cover the entire plant in a profusion of color. It is often used in rock gardens, borders, and as a groundcover.

Aurinia species are adapted to harsh, rocky environments and prefer well-drained soil and full sun. They are generally hardy and can tolerate cold temperatures. Propagation is typically done by seed or cuttings. Several cultivars of Aurinia saxatilis exist, offering variations in flower color and plant habit. The genus name Aurinia derives from the Latin word "aurum," meaning gold, referring to the characteristic yellow flowers of the species.
