Family: AsteraceaeLife cycle: Perennial
Roots: Shallow, fibrous, creeping
Basel rosettes are composed of long, narrow, linear leaves that are covered in small, fine hairs
Flowers: each plant may have 2 to 8 flowers, which can range from 6 to 30 inches tall
Note: Similar plant structure with yellow flowers is known as yellow hawkweed complex. There are several species with one being a listed noxious weed. However, identification can be tricky due to their similar characteristics but growing patterns will help identify between species in the field.
Effective control methods:
Repeated cultivation/digging: This is effective only on small under-established sites. Stolons and rhizomes are fibrous but weak so it’s important to remove and contain (then dispose of properly) all ‘root’ looking structures.
inEffective control methods:
Mowing orange hawkweed will NOT control this weed because it reproduces through stolons and rhizomes. Mowing may reduce the seed bank for a short time but this plant will adapt and begin to produce flowers/seeds at a lower level.
