The Story
Plant Bio
Cuscuta salina is a parasitic annual vine native to the salt marshes and alkaline flats of western North America. Lacking chlorophyll, roots, and functional leaves, it survives entirely by wrapping its thread-like orange stems around host plants to extract moisture and nutrients.
This species is distinguished by its strict adaptation to saline environments, where it forms dense, tangled golden mats over halophytic hosts like pickleweed. In summer, it produces clusters of tiny, white, bell-shaped flowers that support native coastal pollinators.

Planting
How to Grow
- Select a sunny, wet site containing established populations of native host plants like pickleweed or fleshy jaumea.
- Sow seeds directly at the base of the host plants during early spring when soil moisture is high.
- Ensure the area remains seasonally saturated or subject to natural tidal action to support host health.
- Allow the germinating tendrils to naturally find and twine around the host stems without physical intervention.
Pro Tip
Establishment requires sowing seeds directly adjacent to an active host plant such as Salicornia; without immediate physical contact to a host stem within days of germination, the seedling will perish.

Care Guide
Do
- Maintain a healthy stand of host plants to ensure the parasite has a viable nutrient source.
- Provide full sun exposure to mimic natural open salt marsh conditions.
- Allow the plant to complete its annual lifecycle and drop seed naturally for the following year.
Don't
- Do not apply fertilizers, as the plant derives all its nutrition directly from its host.
- Do not plant near agricultural crops or ornamental gardens due to the risk of spreading to non-target species.
- Do not attempt to transplant established vines without their host plants, as they lack roots to survive.
