Curly-cup gumweed is a sturdy prairie native with bright yellow daisy-like flowers that bloom from June through September. This compact perennial forms low mounds and tolerates drought extremely well once established. The flowers have distinctive curved bracts that curl backward, giving the plant its common name.
In an HOA neighborhood
Curly-cup Gumweed 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.
- Common name includes 'weed' which creates negative perception
- Can look scraggly and unkempt when not blooming
- May be considered too wild-looking for formal landscapes
