Aurinia

Aurinia is a genus of flowering plants belonging to the family Brassicaceae (mustard family). It is native to Europe and parts of Asia. Plants of the Aurinia genus are often characterized by their silvery-grey foliage and bright yellow flowers, making them popular choices for rock gardens and other drought-tolerant landscapes.

Description:

Aurinia species are typically perennials, though some may be biennials. They are known for their low-growing habit and woody base. The leaves are often covered in fine hairs, giving them a distinctive silvery or grey appearance. The flowers are usually yellow, though variations may exist. They are typically produced in clusters (racemes) at the end of stems.

Taxonomy:

The genus Aurinia has been subject to taxonomic revisions over time. Some species previously classified under Aurinia may now be found in other genera within the Brassicaceae family. It is closely related to Alyssum, and differentiating between the two can sometimes be challenging.

Cultivation:

Aurinia plants are relatively easy to grow and are favored for their drought tolerance and ability to thrive in poor soils. They prefer full sun and well-drained conditions. Propagation is commonly done through seeds or cuttings.

Uses:

Aurinia is primarily used as an ornamental plant in gardens and landscaping. Its bright flowers and attractive foliage make it a popular choice for adding color and texture to rock gardens, borders, and other outdoor spaces. Its drought tolerance makes it suitable for xeriscaping.
