Blueweed - Helianthus ciliaris
THIS PAGE IS UNDER CONSTRUCTION.
Texas blueweed so named because of its blue-green aspect is a glabrous
perennial 3-6 dm tall. The stems arise from creeping rootstocks. The leaves
are opposite, narrow to broadly lanceolate with hairy margins. The inflorescence
is a head with reddish disk flowers and yellow ray flowers. The involucral
bracts are ovate to oblong with either rounded or pointed tips. The achenes
are four-angled, grayish brown with a pappus of two scales.
Blueweed can be found in cropland and disturbed sites often in dry sandy
soil.The creeping rootstocks and aggressive habit make the plant a serious
weed in some locations.
