DESCRIPTION:
Branched broomrape is an annual to perennial root parasite that has no chlorophyll and lacks conspicuous foliage. It is visible above ground only when flowering. The young plant is a yellowish spear or spike. Mature plants are 4 to 12 inches (10-30 cm) tall. Stems and flower clusters are covered with very short glandular hairs and leaves are reduced to alternate scales. Aboveground parts are pale to bright yellow and stems are slender with many branches from the base. Its seeds spread in water and in contaminated soil. Flowers resemble small snapdragons, ranging in color from white to blue or violet. Branched broomrape is a Class A noxious weed in California. If you find it, contact your Agricultural Commissioner.
