Twinflowered marshmarigold (the former variety leptosepala) as seen from High Prairie, Mt. Hood National Forest.....June 21, 2014.
Marshmarigold is a low growing, beautiful perennial wildflower of very moist places. The basal leaves are long petioled and broadly rounded or kidney-shaped or oval-shaped with a dark green, shiny upper surface. The petiole is longer than the blade, which may be up to 10 cm long and wide.
The flowers are actually six to twelve white sepals. Two flowers are usually found per plant. Petals are lacking. The yellow stamens and greenish pistils are centrally located and both are numerous. Marshmarigolds bloom within weeks of the snow melting. The fruits are many seeded pods.
This is a fine wildflower for the moist garden, and seems to be hardy in moist lowland gardens west of the Cascades once established. When established in thick stands, it is very attractive when in bloom.
Marshmarigold is found in very moist areas, including streambanks, moist meadows, and seeps from montane forests into the alpine zone.
Marshmarigold is widely distributed in mountainous areas from Alaska south through British Columbia to the Olympic Mts and Cascades of Washington and Oregon south into California. It is found eastward into Idaho, Colorado, and Utah.
