Goldenthread
Cuscuta pacifica
  
About Goldenthread (Cuscuta pacifica) 0 Nurseries Carry This Plant Cuscuta pacifica is a species of dodder. Its common name is goldenthread. The plant is native to the coast of western North America from British Columbia to Baja California,. It is a halophyte, living in coastal salt marsh habitats, such as the San Francisco Bay. Cuscuta pacifica is a slender annual vine with yellowish thread-like stems that wrap tightly around other plants. The leaves are reduced to tiny scales, and it possesses no roots because it is a parasitic plant, like all Cuscuta, and taps nutrients from host plants with its haustoria. The salt marsh dodder produces flowers with bell-shaped, white glandular corollas with five pointed triangular lobes. It tends to parasitize Salicornia, but also may be found on other species such as Jaumea carnosa and Grindelia stricta. Varieties: The species includes two Varieties: Cuscuta pacifica var. pacifica is significantly more common, occurring throughout the species range. Cuscuta pacifica var. papillata is a very rare endemic of sand-dune habitats in Mendocino County.
