- Description
-
Panicled Hawkweed is an herbaceous perennial, weedy wildflower in the daisy family, a native of eastern Canada and eastern United States, and flowering from summer into fall. It can be found growing in dry to moist forests and woodlands and along trail sides as well as man-made or disturbed habits. In spring, the plant produces a leafy stalk rising from a caudex (a short persistent stem base at or just below the surface of the soil). By summer, the stem may have as many as 50 yellow flower heads in a flat-topped array. As winter comes on, the stem dies back and the caudex overwinters to produce next spring's stem.
Panicled Hawkweed prefers full or partial sun, moist to dry conditions, and slightly acidic sandy soil. The plant is commonly found in dry sandy areas.
The plant has fibrous roots and long rhizomes and is considered weedy. For removal, dig or hand pull the plants out ensuring that the rhizomes are also removed. This ensures that clonal offsets do not establish colonies of plants.
Insects, Diseases, and Other Plant Problems:
No known diseases or insect pests.
