Arrow-weed is a tall, fast-growing shrub that forms dense colonies along washes and wet areas. This deciduous plant can reach 10-20 feet tall and produces clusters of small pink to purple flowers from summer through fall. It's naturally found in riparian areas and thrives in low water conditions once established.
In an HOA neighborhood
Arrow-weed takes more care to keep looking intentional in a front yard. Maintenance level: high. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Grows extremely large and can overwhelm typical residential spaces
- Spreads aggressively through underground runners
- Looks bare and scraggly during winter dormancy
Wildlife value
The long blooming period attracts numerous pollinators including native bees, butterflies, and moths from June through September. Birds often use the dense growth for nesting cover and the seeds provide food for wildlife.
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.
