Robinia pseudoacacia

Black Locust

Categories: Flowering/Ornamental Trees

A fast-growing native deciduous tree, Black Locust is capable of reaching 70 to 80 feet in height but is more often seen 30 to 50 feet tall with a spread of 20 to 35 feet (Fig. 1). The upright growth and short, irregular branches form an open canopy and cast light shade below the tree, allowing a lawn to thrive

More About Robinia pseudoacacia

  • Drought tolerant once established. Rapid growing.
  • Great street, park or specimen tree
  • Majestic specimens with"ghostly" appearence

For approximately a 10-day period in late spring, the trees are festooned with four to eight-inch-long, dense clusters of extremely fragrant, one-inch white blossoms (similar to sweet-peas) which are literally "alive" with the bustling activity of visiting bees. The honey which is produced is quite delicious and sought-after.
