Gleditsia triacanthos Linnaeus. Honey Locust, Honeyshuck. Phen: Apr-early Jun; Jul-Nov. Hab: Woodlands, forests (generally bottomland), fencerows, often planted as a street tree. Dist: The native distribution is believed to be from w. NY (although see Werier 2017; Werier et al. 2023, who consider this taxon non-native throughout NY) west to se. SD, south to Panhandle FL and TX (in and west of the Blue Ridge); its occurrence in the more eastern portions of our region (east of the Blue Ridge) appears to be as an adventive. Kimball, Whyte, & Crites (2010) found remains in an archeological site near Asheville NC (Blue Ridge) dated at ca. 500 A.D.

ID notes: The trunks are normally beset with lengthy, branched thorns, an apparent vestige of defense against herbivory from Pleistocene megafauna; however, thornless trees (forma inermis Zabel) are favored in horticultural plantings and are more typically encountered.
