[Wikipedia] Range, Habitat, Uses: It is native to western North America from British Columbia to California to Colorado, where it grows in several habitat types including coniferous forest, chaparral, and various types of woodland.
The plentiful inflorescences are long clusters of white flowers. The fruit is a three-lobed capsule a few millimeters long which snaps open explosively to expel the three seeds onto the soil, where they may remain in a buried seed bank for well over 200 years before sprouting.[1] The seed is coated in a very hard outer layer that must be scarified, generally by wildfire, before it can germinate.[1] Like most other ceanothus, this species fixes nitrogen via actinomycetes in its root nodules.[1]
Uses
Deer and elk browse the plant during winter.[2]
Some Plateau Indian tribes drank a boil of this plant to induce sweating as a treatment for colds, fevers, and influenza. Leaves were also used when rinsing to help prevent dandruff.[3]
Ceanothus velutinus was known as "red root" by many Native American tribes due to the color of the inner root bark, and was used as a medicine for treating lymphatic disorders, ovarian cysts, fibroid tumors, and tonsillitis. Clinical studies of the alkaloid compounds in C. velutinus has verified its effectiveness in treating high blood pressure and lymphatic blockages.[4] (link added by Mary Ann Machi)
