Marsh-elder is a tall annual wildflower that produces small greenish flowers in late summer. This native plant can reach up to 6 feet tall and has a somewhat coarse, weedy appearance that's better suited for naturalized areas than formal gardens.
In an HOA neighborhood
Marsh-elder 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.
- Very tall and can appear weedy
