Common name: California brome
Abbreviation code (Codon): BRCA
Perennial It is hardy to zone 0. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Flies, bees, beetles. The plant is self-fertile. The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil.
N. America. N.E. Asia.
Bog Garden; Cultivated Beds; Banks of streams, in swamps or on wet rocks, Labrador to Alaska and south to California.
Edible Parts: Leaves. Young leaves - raw or cooked. The rosettes of the dark green shiny leaves are eaten raw or cooked. A hot, cress-like flavor.
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in most parts of this country. The following notes are based on the general needs of the genus. Succeeds in sun or shade in a moist well-drained soil.
Seed - sow in situ in early spring to early summer.
Seed sample from: 2008
Average measurement: 14.6 x 1.5 x 1.5
Measurement range: L: 13.5 – 16 W: 1.1 – 1.8 D: 1.2 - 2
Shape: Inner seed is about ½ the size of its husk, and brown.
Color:Seed husk tan, tending to be whiter toward hilium, and browner towards awn.
Surface:Hilium is somewhat glossy, while rest of husk is very hairy. Awn is brown and straight. Surface of seed longitudinally striate and glossy.
Basic Explanations and Assumptions:
The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.
Measurements included are the mean average for each measurement of ten separate seeds.
All measurements in millimeters unless otherwise noted.
