Adans., Fam. Plant. II (1763) 420.

Fam:   Cruciferae Juss.
Genus:   Aubrieta Adans.
English Name: Aubretia

Description:

Tussock-similar perennial, herbaceous plants small, densely covered most often with star-shaped or star-shaped and unbranched hairs, rarely naked. Stems erect, rose slightly to recumbent, zigzag curved, richly leaved. Leaves consistent, simple, narrowly lanceolate to linear lanceolate, or back ovoid or oblong wedge to back ovoid or rhombic, often entire or with 1 - 3 teeth on both sides. Inflorescences loose clusters, with few large flowers with long stems. Sepals erect, each other overlapping, external with clearly bulky expansion at the base. Petals pink or violet, rarely white, reverse ovate to rounded, with a long fingernail. The stems of the stamens flat, external stamens atop usually with tooth and longer anthers of interior stamens. External nectar glands located at the base of short stamens, semi annular and extended down into two horns. Middle nectar glands are missing. Pistil oblong, with 24 - 36 ovules; ovary seated. The bar long with cumulus stigma. Fruits linear pods to short elliptical little pods. Protruding buttons or flattened, with thin mean streak or net covered with streaks. The bund thin, sometimes transparent, consists of polygonal cells with wavy cell membranes. Seeds located in 2 rows in each bay, small, ovoid, flat.
Economic importance. Can be used as ornamental plants, forming cushions on rockeries, in rock crevices and dry walls. Suitable for open sunny places.

¹ Developed by Iv. Assenov.
² In determining to take into account measurements only fully ripe pods, and the ratio between the length of the pistil and the bar to measure the lowest fully developed color of the inflorescence.

Aubrieta (commonly known as Aubretia) is a genus of about 12 species of flowering plants in the cabbage family Brassicaceae. The genus is named after Claude Aubriet, a French flower-painter. It originates from southern Europe east to central Asia but is now a common garden escape throughout Europe. It is a low, spreading plant, hardy, evergreen and perennial, with small violet, pink or white flowers, and inhabits rocks and banks. It prefers light, well-drained soil, is tolerant of a wide pH range, and can grow in partial shade or full sun.[1]
