Hieracium paniculatum L.

Panicled hawkweed

About plant names...

Panicled hawkweed is a native of eastern North America.

Identification: From a base on the ground that survives the winter, this hawkweed produces stems up to 3' (1 m) high, with sparse leaves and hairs on the lower stem and leaves that are ⅛-⅜" (3-10 mm) long. Leaves are narrow, with irregularly toothed margins and whitish undersides. The top portion of the plant branches in a delicate tracery of sinuous, hairless, thin-branched flowering heads. Each of the dozens of flowers are less than ½" (1.5 cm) in length, with fewer than 20 florets.
