Micranthes oregana (formerly Saxifraga oregana)

This moisture-loving perennial is equally unique as it is attractive. In early spring, it emerges as a basal rosette of dense, lance shaped leaves up to 10” long. Then, stout flower stalks, or peduncles, protrude from the center and grow up to three feet tall to flaunt clusters of countless, dainty white-petaled flowers. This species is fun to spot while hiking in vernal or boggy areas and even more rewarding to find a place to establish it at home.

Gardening with Oregon Saxifrage: Oregon saxifrage is a hardy and long-lived perennial that will accent your garden with its unique, stout flower spires. It’s ideal in mostly to full sun areas, like a raingarden or wet meadow, that are waterlogged from late fall through early spring. They will go dormant after flowering, allowing them to tolerate summer dryness just fine.
