Species: Robinia pseudoacacia

History: Native to small portion of the United States, the tree first became known to Western science in 1607 when British colonists in Jamestown used it to build houses. It was introduced to Britain in 1636 and has since been used as a landscaping tree in many countries around the world. It is unfortunately considered invasive in many places due to its intense suckering habit and ability to fix nitrogen, allowing it to thrive even in poor soils. However, its hard wood has many uses and the flowers are eaten in numerous European countries and Japan, and it is used medicinally in India.

Why We Grow It: While this tree is considered invasive to southern Ontario as it grows quickly and aggressively, we feel when it is grown with control and awareness, it can be a powerful ally for the following reasons:

  • it is a great pioneer species in ecologically disturbed spaces thanks to its resilience and ability to grow and produce nitrogen
  • even in poor soil it provides erosion control with its spreading, shallow root system
  • it's a fast growing hardwood
  • it is preferred for firewood and furniture (60x more rot resistant than cedar)
  • bees appreciate it's showy blooms, which are edible and can be enjoyed in salads, jams, cooking and baking, check out Fiddlehead Nursery's locust-flower patty recipe! 
  • On a farm/tended space, they provide valuable shade for livestock, thicken fencerows, provide habitat for wildlife, increase soil health, and add nitrogen, etc. and are easily managed.

However it is strongly advised not to plant in untended bushland due to its quick and aggressive spread, and resilience once it is established in an area making it quite difficult to remove.
