Partridge Pea (Cassia Fasciculata) - A versatile annual that is perfect for a naturalized setting or meadow! Grow Partridge Pea seeds for a variety of settings which include, wildlife habitat improvement, erosion control, and to beautify a natural setting with an attractive wild flower. Cassia Fasciculata Partridge Pea has large, showy, yellow flowers. Each Partridge Pea flower is marked with red and is followed by a narrow pod. The flowers are a good source of nectar for bees and butterflies, and the pods produce flower seed which is a major food source for game birds and songbirds. Some of the wildlife that benefit from Partridge Pea seeds are prairie-chicken, ring-necked pheasant, mallard, grassland birds, deer, turkey, dove, pheasant, rabbit, and quail. The Cassia Partridge Pea plants often grow in dense stands, producing foliage that furnishes cover for upland game birds, small mammals, small non-game birds, and waterfowl.
Partridge Pea is considered an important honey plant as well. It is quite attractive in regards to both its foliage and flowering habit. Partridge Pea uses include erosion control along road banks and stream banks. Partridge Pea prefers full sun and average to dry conditions. The soil can contain sand, loam, gravel, or clay, and because it is a legume, it will add nitrogen to the soil. Partridge Pea is easy to grow from flower seeds, but can spread readily in dry, open situations as it self-sows. Partridge Pea grows wild throughout the Midwest, eastern, and southern United States in zones 3 to 9.
Growing Partridge Pea seed is not difficult. Partridge Pea seeds can be planted from late winter (March) to late spring (May). A cold treatment by refrigerating the Cassia seed for 30 days is helpful in aiding germination. After the cold treatment, broadcast the Partridge Pea flower seed in weed-free prepared soil. Rake the seed in and cover 1/4 inch. Keep the seeds moist. Established stands of Partridge Pea plants will disappear without some general maintenance. In spring, remove weeds, small brush, and old sod to expose the soil so that the flower seeds that have been self-sown can come in good contact with it.
