Brimeura Salisb. is a small bulbous genus in the Hyacinthaceae Batsch ex Borkh., the Hyacinth family, (syn. Asparagaceae Juss., the Asparagus family), formerly regarded as Hyacinthus Tourn. ex L. and related to Scilla L.
Brimeura amethystina (L.) Chourd syn. Hyacinthus amethystinus L. from rocky and grassy places in the Pyrenees to northeast Spain, Slovenia, and Croatia prefers sun. Flowers are blue and there is also a white form. The narrow grasslike linear leaves appear late fall to winter and the flowers spring to early summer. This species is described as good for naturalizing, but the only ones I planted out in coastal Northern California disappeared before they ever bloomed. Plants grown from seed and kept in pots dry in summer took many years before they finally bloomed. Photos from Mary Sue Ittner.
The white form is sometimes described as Brimeura amethystina ‘Alba’. These plants were grown from seed and grown in a pot. They were photographed in 2007 by Mary Sue Ittner in their first bloom from seed planted in 2002.
