Rock spirea (Holodiscus dumosus) is a very drought tolerant native shrub reaching 6’ in height and width. It has fragrant leaves (when brushed against) and it produces sprays of small, white flowers at the ends of arching branches. After the flowers fade, the seeds are also ornamental, producing pinkish seed heads. Rock Spirea does best in full sun to half shade and may decline if watered too much.
You can often find it growing in its native habitat in the mountains west of Cheyenne.
