(Rose acacia, Bristly locust)
This showy flowering shrub grows to 8 feet tall and wide and features dark green, compound pinnate leaves on bristly stems and pendant clusters of fragrant, pea-like, rose-pink flowers that are attractive to bees and butterflies in late spring and early summer. The flowers are occasionally followed by bristly, reddish-brown seed pods. Native to the southeastern United States, this aggressive shrub spreads by suckers and is considered invasive in Michigan, New Jersey, Ohio, Pennsylvania, and Washington. All parts of this plant are at least mildly poisonous.
