I have Nuttall's toothwort, Cardamine nuttallii growing in my garden, transplanted from the nearby Coast Range. If it flowers this year, and I manage to get some seeds, I will send some to the BX. It likes cool damp soils in part shade, and has lovely pale pink flowers in early spring. This is a perennial that flowers early and then dies down for the summer. New leaves appear in fall, and overwinter. Kathleen Kathleen Sayce PNW Coast, WHZ 8, dryish cool summers & mild wet winters
