A grouping of three mature black locusts (Robinia pseudoacacia) grace the edges of this courtyard. Black locusts are not native to this region, but are considered naturalized, meaning they are able to reproduce themselves and thrive. These three trees are likely relatives, their parent an older tree somewhere else in the neighbourhood. As seeds, they were blown here by the wind coming to rest up against a fence or under a hedge that at one time lined the edge of the sidewalk. The seeds germinated and took root, being close to the building they were not cut by lawnmowers allowing them to grow into mature trees. They have made this courtyard their home ever since.
