(Ethnobotany database)

Gleditsia hosts caterpillars of 43 species
of butterflies and moths, in some areas.

Most legumes (but not this species) cooperate with a bacterium that fixes atmospheric nitrogen into a form usable by plants and animals.

In the wild, this tree's branches and trunk have large smooth thorns.

Often grows in clonal colonies [1] —look around for other stems!

Planting info (SW Michigan). 

Honey locust have large tough seedpods, which contain sweet pulp and large seeds, with a thick waterproof coating that needs to be cut or abraded before 🌱︎ germination.  This seed protection probably evolved with and to be spread by 🐘︎ mammoth  genus Mammuthus or 🐫︎ camel  family Camelidae.   After the Holocene extinction removed large herbivorous megafauna, poor seed-dispersal caused the plant's range to decline to the central 🇺🇸 USA.

Lately, 🐮︎ cattle  genus Bos may have taken the role as seed disperser. [2]
