Rydberg's beardtongue is a compact native perennial that produces tubular flowers in late spring through summer. This drought-tolerant wildflower forms neat clumps and works well in rock gardens and xeriscaping designs.
In an HOA neighborhood
Rydberg's Beardtongue 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.
- Appears too wild and informal for front yard landscaping
- Unknown winter appearance may look untidy
- May be perceived as weedy by conservative HOAs
Wildlife value
The tubular flowers attract hummingbirds and native bees during the blooming season from May through July.
