What a slew of common names for this demure little beauty.  Named after John Clayton (1693-1773), one of America's first botanists, Claytonia sibirica is native to the damp woods and slopes of Siberia and was introduced to England in the 18th Century.  It is now found naturally in the Pacific Northwest United States, Alaska, and in my shade garden in North Carolina (among other places).  The green, fleshy leaves form rosettes (edible, I have read) with stems holding numerous white, pink veined, five-petaled flowers.  Claytonia grows from six to 12 inches in the shade of moist woods and blooms its head off until frost. .  Quarts.
