About

Cuscuta epithymum is an annual herbaceous parasite characterized by its slender, leafless, thread-like stems that wrap tightly around host plants to obtain nutrients. This species does not contain chlorophyll and instead features small scale-like structures along its pink, red, yellow, or purple stems, which can reach lengths of up to 1 meter, depending on the availability of hosts. From June to October, it produces small, bell-shaped flowers in white or pink, grouped closely together, with pollination mainly facilitated by ants, bees, and flies.

Care notes

Cultivation
Thrives in open, sunny habitats like heathlands, grasslands, coastal dunes, and sandy or acidic soils. It's particularly common in nutrient-poor, dry conditions where its host plants, such as heather (Calluna) and gorse (Ulex), are abundant
Pruning
No pruning required
Propagation
Primarily propagates by seed, which can remain dormant in soil for years. Once sprouted, seedlings must quickly locate a host plant or perish
Pest resistance
Generally pest-free
Disease resistance
