Partridge pea

Chamaecrista fasciculata

Partridge pea (Chamaecrista fasciculata) is a native annual legume that blooms the first season from a spring seeding — one of the very few CRP mix species that shows color in year one. It fixes nitrogen, produces high-energy seed for bobwhite quail, and provides extrafloral nectar that supports beneficial insects all summer.

Why landowners plant partridge pea

  • Blooms in year one, giving landowners visible success while perennials establish.
  • Seed is a preferred winter food for bobwhite quail and other ground-feeding birds.
  • Nitrogen fixation improves poor and eroded soils.
  • Extrafloral nectaries feed ants, wasps, and beneficial predators beyond the bloom window.

Site fit

Partridge pea excels on sandy, gravelly, and eroded ground where perennial forbs establish slowly. It is a standard component of CP33 quail buffers, CP42 pollinator mixes, firebreak plantings, and native food plots. Keep rates modest — heavy rates can shade out slow perennial seedlings.

Establishment

Hard-seeded; scarified seed germinates readily with spring planting. Plant 1/4 to 1/2 inch deep. Because it is an annual, it reseeds itself in disturbed openings and gradually fades as the perennial matrix closes in.

Management

Responds strongly to disturbance — burning, light disking, or mid-contract management brings partridge pea back from the seed bank for several years.

Frequently asked questions

Is partridge pea an annual or a perennial?

Partridge pea is a native annual. It completes its life cycle in one season but reseeds prolifically, so a well-established planting persists for years and rebounds strongly after burning or light disking.

How much partridge pea should be in a CRP mix?

Most mixes use 0.25 to 1 PLS pound per acre. Higher rates create a dense year-one canopy that can shade slow-establishing perennial forbs, so keep it modest unless quail food is the primary goal.
