Common Dodder

<em>Cuscuta gronovii</em>, the common dodder, is a parasitic annual vine in the family Convolvulaceae. This species is distributed across eleven European countries as well as the United States, where it typically inhabits diverse terrestrial environments including wetland margins, roadsides, thickets, and disturbed vegetation. Unlike most plants, <em>Cuscuta gronovii</em> lacks chlorophyll and is entirely dependent on host plants for water and nutrients, which it extracts through specialized structures called haustoria. The common dodder typically has slender, twining orange or yellowish stems and produces small, clustered white or pale pink flowers in late summer. It often parasitizes a broad range of host species, including many herbaceous and shrubby plants. Once attached to a host, it typically sheds its connection to the soil and relies entirely on the host for sustenance. The species is assessed as Least Concern, reflecting its wide distribution and ability to colonize disturbed habitats. Its parasitic life history makes it ecologically notable among flowering plants.
