ALERT: PLEASE CALL 1-866-INVADER IF YOU SUSPECT YOU HAVE FOUND THIS SPECIES
Identification:
Perennial; flowers June to July. Grows 1 1/2 to 4 feet tall. Stems greenish with slender spines 1/4 to 1 3/4 inches long. Leaves wedge-shaped, hairless on the upper surface, 1/4 to 1 1/4 inches long. Flowers small, pea-like, pinkish purple to maroon, occur on short, spine-tipped branches along the upper portion of the plant. Reddish-brown jointed seed pods curved upward, deeply indented with each seed clearly outlined in the pod. This species is not yet known to occur in Oregon.
Impacts:
This plant grows well on dry or moist sites and is reported to spread rapidly along streams and canals. It is strongly competitive with other plants. Its rapid and aggressive growth allows it to out compete both native vegetation and cultivated crops. Because of its rhizomatic growth habit, dense stands may form that are impenetrable because of its spiny stems. It is especially troublesome in cereal and horticultural croplands, where repeated cultivation aids its spread.
Biological
