Antelope Brush
According to the Osoyoos Lake Water Quality Society, the antelope brush ecosystem is one of the most threatened systems in Canada. Antelope brush is a shrub that grows in arid grassland desert regions. The plant is an important part of the Osoyoos desert ecosystem, as it provides food and shelter for many animals in its growing range.
Chocolate Lily
Chocolate lily flowers grow in dry wooded areas and meadows throughout parts of southern British Columbia in Canada and Washington and California in the United States. This flowering plant has actually become quite rare in the wild and though not classified as endangered, is considered a threatened plant species.
Silky Lupine
Silky lupine is a flowering perennial that grows on the dry slopes of the Osoyoos desert region. Silky lupine is readily found throughout the desert, though it provides little sustenance for the wildlife in the area as the plant is toxic to animals including sheep, horses, goats, cattle and humans.
Black Hawthorn
The black hawthorn is a small, shrub-like tree that blooms white flowers among its spreading branches. First noted by the Lewis and Clark expedition in 1806, black hawthorn trees grow in the northwestern region of North America including British Columbia, Alaska, New Mexico and California.
Rabbitbrush
Green and common rabbitbrush are commonly found in the Osoyoos ecosystem. A low shrub plant, it is a source of food, shelter and protection for native wildlife. Both rabbitbrush species thrive in the coarse-textured soil of the desert and is most often found at high elevations between 2,600 and 11,000 feet.
Toothcup
The toothcup plant, also referred to as scarlet toothcup or scarlet ammannia, are summer annuals that produce small pink or purple flowers. They grow in the muddy soil along the Osoyoos Lake shoreline, however, as their habitat is threatened by destruction of the Osoyoos biome, Toothcup plant numbers are depleting and the plant is considered threatened in the region.
