Description Prairie acacia has lovely white puffball flowers which attract a variety of pollinators including bees and butterflies. Like many other member of the Bean family, this species forms relationships with bacteria that can capture nitrogen from the air and improve soil quality, which makes this a good companion plant for trees. Keep in mind that this plant spreads by rhizomes (underground stems) and can fill in a planting area, so give it plenty of room. Consider mixing into a planting with native grasses, or using for erosion control.
