Solomon’s plume grows as a single arching stem lined with broad, pointed leaves, and it ends in a feathery spray of tiny cream-colored flowers. A large plant can stand knee high or taller. The flowers are fragrant, and one cluster can hold dozens of them. After blooming, the clusters set small round berries that start out green with copper speckles and ripen to a see-through deep red.
The plant spreads slowly from thick underground stems and often forms loose colonies. Bees and flies work the spring flowers, and birds and small mammals eat the berries, carrying the seeds to new spots. In fall the leafy stems turn gold and die back to the ground, and fresh shoots come up again in spring.
Around Mt. Hood, look for it in open woods, along forest edges, in clearings and at the margins of moist meadows, from the lower valleys up into middle elevations. It blooms from spring into early summer, when the white plumes stand out in the shade. Its smaller cousin, star-flowered false Solomon’s seal, grows in similar places but carries a short spike of fewer, larger, star-shaped flowers.
How to identify it
Unbranched, arching stems 30 to 90 cm tall with 7 to 12 alternate, stalkless, oval and pointed leaves up to 20 cm long. The stem ends in a branched, fluffy cluster of many tiny cream-white flowers. Berries are round, 5 to 7 mm, green with copper flecks at first and translucent deep red when ripe.
Look-alikes
Star-flowered false Solomon's seal (Maianthemum stellatum) is smaller, with a short, unbranched spike of about 5 to 20 larger, star-shaped flowers, and its young berries are green with dark stripes.
Habitat
Open woodlands, forest edges, clearings and moist meadows from sea level to middle elevations in the mountains. On Mt. Hood it belongs to the lower and middle forest rather than the high country near timberline.
