Grassland Tarweed
Deinandra increscens
About Grassland Tarweed (Deinandra increscens) 0 Nurseries Carry This Plant Deinandra increscens is a species of flowering plant in the aster family known by the common name grassland tarweed. It is endemic to California, where it has been found primarily in Monterey, San Luis Obispo and Santa Barbara Counties (including Santa Cruz and Santa Rosa Islands). A few isolated populations have been reported from Kern and Merced Counties, but these are from urban areas (Cities of Merced and Bakersfield) and probably represent cultivated specimens. Deinandra increscens is an annual up to 100 cm (40 inches) tall. It has numerous flower heads, often tightly clumped together, each with yellow ray florets and disc florets with yellow corollas but red or purple anthers.
