Pigweed is a tall annual wildflower that produces dense clusters of small, inconspicuous flowers from summer into fall. This native plant can reach up to 4 feet tall and thrives in poor soils with minimal water once established.
In an HOA neighborhood
Pigweed 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.

Wildlife value
The flowers attract bees and beetles during the long blooming period from July through September. Seeds provide food for birds and small mammals in late fall.
