Oregon anemone from near the upper portion of the East Hardy Ridge Trail, Beacon Rock State Park...........May 14, 2014.
Oregon anemone is a lovely perennial wildflower generally with one basal leaf and one erect stem with a trio of leaves above the midstem. The stem ranges from 10-30 cm high, arising from stout, scaly, horizontal rhizome. The basal leaf is trifoliolate with each of the 3 leaflets compound ternate, the individual leaflets shallowly lobed once to twice. The stem leaves are similar, with individual leaflets measuring up to 8 cm long with the lateral pair lobed half their length. All leaflets are deeply toothed with 2-5 teeth per side.
The 5 sepals are bluish, bluish-purple, reddish-purple, or whitish in color with the individual sepals ovate-oblong to oblong-elliptic in shape and measuring 12-20 mm long. The 35-100 stamens surround a central cluster of many shorter pistils.
Oregon anemone may be found in open woods and on brushy and open hillsides from moderate to high elevations in the mountains.
Oregon anemone is found primarily on the eastern slopes of the Cascade Mts. from Chelan County in Washington south to the Columbia River Gorge. In Oregon, it may be found in the northern Cascades and northern Coast Range to as far south as Lincoln County. It has also been reported in the Blue Mts. of Oregon.
In the Columbia River Gorge it may be found between the elevations of 500'-4400' from Silver Star Mt. east to near Dog Mt.
