ⓘ Chamaecrista fasciculata

Chamaecrista fasciculata, the partridge pea, is a species of legume native to most of the eastern United States. It is an annual which grows to approximately 0.5 meters tall. It has bright yellow flowers from early summer until first frost, with flowers through the entire flowering season if rainfall is sufficient.

Flowers are hermaphroditic, although some of the plants, less than 5%, do not produce sufficient pollen to reproduce as males. This phenomenon has been investigated in many plants as a possible evolutionary step towards dioecy, in which male and female flowers occur on different plants. C. fasciculata is pollinated only by bees.

The flowers have yellow anthers, the pollen producing reproductive and purple anthers, produce pollen food, but not nectar. Chatty bees as bumblebees, honey bees, Longhorn bees, and leafcutting bees to pollinate the flowers. Have extrafloral nectaries on leaves and stems, which attract a different set of insects: bees, flies, wasps and ants.

It thrives in areas that were recently burned, before declining in numbers in subsequent years. It is an excellent choice for planting in disturbed areas, as it will quickly cover an area, preventing erosion, while still allowing other plants to settle. It is also grown as an ornamental for honey production.
