Oneflowered broomrape is a parasitic wildflower that lacks chlorophyll and derives nutrients from host plants' roots. It produces small, solitary white to pale purple flowers on short stems in late spring and summer. This unusual native plant has a very low, inconspicuous growth habit.
In an HOA neighborhood
Oneflowered 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 unpredictable and potentially harmful to other landscape plants
- Extremely small size makes it appear weedy or incomplete
- Lacks leaves and normal plant structure, creating an odd appearance
Wildlife value
Limited wildlife value due to its small size and parasitic nature, though the small flowers may attract some tiny native bees and flies.
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.
