Identification:
Annual, parasitic plant that lacks chlorophyll; flowers July to October. Stems yellowish, thread-like and twining. Leaves reduced to thread-like scales. Flowers white to pink, numerous, shallow-cupped, and grow in compact clusters.
Impacts:
The non-native form of dodder is a parasite on agricultural crops and drastically reduces yield. The twining stems also hamper harvest of certain high-value crops in California. It also is an alternate host for beet yellows, cucumber mosaic, and tobacco etch viruses. There are many native species of dodder that create no economic harm.
