Frosted hawthorn is a small to medium native tree that produces clusters of white flowers in spring followed by small red fruits. This deciduous tree develops an attractive rounded canopy and provides seasonal interest with spring blooms, summer shade, and fall color.
In an HOA neighborhood
Frosted Hawthorn takes more care to keep looking intentional in a front yard. Maintenance level: moderate. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
- Very large mature size (10-20 feet) may overwhelm front yards
- Thorny branches create maintenance challenges
- Can appear irregular and wild without regular pruning
Wildlife value
The spring flowers attract bees, beetles, and flies for pollination. The small fruits provide food for birds, and the dense branching offers nesting sites for various songbird species.
