Nodding Beggarsticks (Nodding Bur Marigold)
Bidens cernua

Preferred Water Depth and Inundation Tolerance

Prefers saturated soil. Species tolerates seasonally flooded conditions for short durations.

Wildlife Value

Provides wildlife cover. Waterfowl, shorebirds, songbirds, and small mammals consume achenes.


Used in upper shoreline zones and in vegetated swales. A good pioneer species.

Availability, Establishment, and Maintenance

  • Plants and achenes are available from commercial vendors.
  • Achenes should be broadcast on wet mudflats or shorelines and raked into the soil.
  • Achenes require cold (34-36o F) moist stratification for several months before being exposed to warm temperatures for optimum germination.
  • Achenes may be fall planted after drawdown on mudflats or shorelines to allow winter exposure. Drawdown in early summer will cause explosive growth from fall planted achenes.
  • Early summer shallow flooding followed by drawdown promotes best seed production from established plants.
