Astragalus crassicarpus

Common Name: Ground Plum

Astragalus crassicarpus, commonly known as Ground Plum, is a low-growing perennial that typically reaches 4 to 24 inches in height. It has pinnately compound leaves and produces clusters of purple to pink pea-like flowers in early spring, followed by edible, plum-like seed pods. This species is commonly found in dry prairies and open fields, preferring well-drained sandy or loamy soils. Ground Plum has been used historically as a food source by Native Americans. In landscaping, it is valued for its early blooms and unique fruit, making it suitable for rock gardens and prairie restorations.

Sowing Information

For most homeowners, the recommended method is to hand-broadcast seed at a minimum rate of 16–64 PLS (Pure Live Seed) ounces per acre. To ensure even coverage, broadcast the seed in perpendicular passes across the site. Grass seed should be broadcast first and lightly raked into the soil. Afterward, apply a light mulch layer using clean, seed-free straw or, preferably, our native Little Bluestem straw, available at our retail garden centers. Once mulching is complete, broadcast native wildflower seed over the area without raking it in. A good rainfall or thorough watering will provide sufficient soil contact for successful germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
