Rock spirea (Holodiscus dumosus) is a compact, drought-adapted native shrub in the rose family, producing cascading clusters of creamy-white flowers in summer. It performs best in well-drained soils in a partly shaded to sunny location and needs little supplemental water once established. This low-maintenance shrub is excellent for naturalistic landscapes, slopes, and wildlife gardens.
