Clustered broomrape is a parasitic wildflower that lacks chlorophyll and cannot photosynthesize on its own. It attaches to the roots of other plants, particularly sagebrush and other shrubs, to obtain nutrients. The plant produces clusters of tubular, yellowish to purplish flowers on short, thick stems.

In an HOA neighborhood

Cluster Broomrape takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.

  • Parasitic nature makes it unsuitable for maintained landscapes
  • Unusual appearance may be perceived as diseased or dying plants
  • Cannot be cultivated or controlled like typical garden plants

Wildlife value

This native parasitic plant provides nectar for various small pollinators including native bees and flies. Its specialized nature means it has co-evolved relationships with specific host plants and their associated wildlife communities.

Native range data from the USDA PLANTS Database and regional native plant society lists. Pollinator and host plant associations compiled from GBIF, iNaturalist, and published ecological literature.
