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.

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.

Latitudinal cross section: elliptical BRCA lat.png

Longitudinal cross section: elliptical BRCA long.png

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.
