DESCRIPTION:
Dodder is an annual parasitic weed that grows only by penetrating tissues
of host plants to obtain water and nutrients. Seedlings must
attach
to a suitable host within a few days of germination or they die.
Threadlike, leafless stems twine around host plants, eventually
creating a tangled mat. Each plant produces thousands of hard seeds
that can remain dormant in the soil for years. Flowers and seed
capsules are borne in clusters. Each flower is about 1/8 inch (3 mm) long.
