Partridge Pea, or Chamaecrista fasciulata, is a great addition to any butterfly garden, as it is a larval host for many butterflies and attracts bees and other pollinating insects. It is an annual which sprouts in early spring, blooms late spring, and reseeds by early fall (typically). It grows to around 3ft tall and wide. It enjoys full sun and is drought tolerant.
A seed pack contains 20-30 seeds.
