CURLYCUP GUMWEED (Grindelia squarrosa ) GROWTH HABIT: : Annual, Biennial, or Perennial. Starts growth in early spring, flowers July to August, reproduces from seeds. LEAVES: Alternate and oblong with toothed edges, gland-dotted, and gummy. STEMS: An erect, tall forb, growing 1 to 3 feet tall, with 1 to several branched stems. FRUITS/SEEDS: Fruit is an achene. FLOWER: Numerous and yellow. There are bracts at the base of the flower which are shiny, sticky, and curved downward (hence the name "squarrose" in the name). Fruit is an achene. ROOTS: Grows from a taproot, branching above. OTHER: Curlycup gumweed is unpalatable to cattle, sheep, and horses, though sheep will occasionally crop flower heads in the absence of other forage. Tannins, volatile oils, resins, bitter alkaloids, and glucosides give it an unpleasant taste. If curlycup gumweed is consumed, it may lead to poisoning due to the selenium the plant can accumulate. It is resistant to grazing and drought.
