Basal-leaf rosinweed is a tall native perennial that forms a clump of large leaves at ground level with bright yellow sunflower-like blooms on tall stems in summer. The flowers are showy and long-lasting, making it an excellent choice for the back of perennial borders. It takes a few years to establish but becomes very drought tolerant once mature.
In an HOA neighborhood
Basal-leaf Rosinweed 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 height may violate typical HOA height restrictions
- Can look sparse or weedy in first year of establishment
- Large basal leaves may appear too informal for front yard settings
Wildlife value
Host plant for American lady butterfly.
The bright yellow flowers attract numerous bees, butterflies, and beetles during the long summer bloom period. Seeds provide food for goldfinches and other birds in fall.
