Chamaecrista fasciculata (Partridge Pea) is a species of legume native to most of the eastern United States.[1] It is an annual which grows to approximately 0.5 meters tall.[1] It has bright yellow flowers from early summer until first frost,[2] with flowers through the entire flowering season if rainfall is sufficient.[1]
The flowers are hermaphroditic, although a fraction of plants, less than 5%, do not produce sufficient pollen to reproduce as males. This phenomenon has been studied in a variety of plants as a possible evolutionary step towards dioecy, in which male and female flowers occur on separate plants.[2] C. fasciculata is pollinated only by bees.[3]
It thrives in areas that have been burned recently before declining in number in the following years.[1] It is considered an excellent choice for planting in disturbed areas, as it will quickly cover an area, preventing erosion, while still allowing other plants to become established.[1] It is also grown as an ornamental or for honey production.[1]
