Prickly Lettuce Flowers |
|
Prickly lettuce is a winter annual or
biennial that reproduces only by seed, but may overwinter as a rosette. Flowers are
present July to September. Mature plants are 1 to 5 feet tall with branches primarily in
the upper flowering portion of the plant. Roots, stems, and leaves exude a milky juice
when broken. Flowers are pale to bright yellow and borne on slender stalks, terminally at
branch ends. This weed is native to Europe, but now occurs throughout the United States.
It thrives on nutrient rich soils. It is a common weed in orchards, ornamental stock,
horticultural and agronomic crops, and roadsides. This species may hydridize with
cultivated lettuce. |
