Interesting Notes about Black Locust:

An interesting tree with twisted or zigzagged branching and spines which are most noticeable in the winter landscape or when pruning.  It is a good choice for naturalizing because of the spines plus it suckers freely and is prone to weak branching.  The beautiful flowers are adored by bees and make excellent honey as a result.  This tree is particularly good for growing in really, really poor soils, like what would be found next to a highway or in dry, desolate areas and grows where most other trees do not.
