Green Alum Root. Fantastic native Heuchera found east of the Cascades but a stellar garden plant on the west side too. Handsome scalloped leaves form a tight evergreen clump. For weeks and weeks in late spring to summer 20″ spikes have columns of small green flowers at the top. Very pretty. Amazing massed in part shade and rich to average well drained soil. Regular summer water though established plants thrive on very little. A pretty Oregon native perennial. Thrives in such diverse places as partly shady hellstrips to the front of borders. Not bothered by pest and disease and much more durable than the hybrids. Easy to grow. Climate adapted. Oregon native plant.
