这种花挂（生长）在墙上，似乎花也懂得，不要在生长，否则就和草混合在一起了，因此，花和草保持了距离

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。
