Weed - Chondrilla juncea
THIS PAGE IS UNDER CONSTRUCTION.
Skeleton weed is a highly branched wiry stemmed biennial or perennial
up to 1.5 m tall, with milky sap. The lowermost 4-6 in. of the stem have
downward bent coarse red hairs. A dandelion-like basal rosette of sharply
toothed leaves whithers as the stem develops. The cauline leaves are small
and inconspicuous. The inflorescence is a head containing 7-15 strap-shaped
yellow ray flowers distinctly toothed at the margin. The small brown-to-black
ribbed achenes are terminated by a pappus of white capillary bristles.
Skeleton weed is common along roadsides, in fields, pastures, vineyards,
and waste places. It easily establishes on disturbed sites. A single plant
can annually produce up to 15,000 seeds.
Skeleton weed displaces native species. The deep root system which can
extend up to 8 ft in the soil makes the plant difficult to control.
