Honey-locust ‘Inermis’
Gleditsia Triacanthos
Occurs naturally in Southwestern Ontario and into the USA. Occasionally planted in New Brunswick. The ‘Inermis’ variety is most commonly planted as it lacks the dangerous thorns. Male and female flowers are on separate branches with some ‘perfect’ flowers on same tree. They attract bees, butterflies and other insect pollinators. It is debated whether the roots of this tree can fix atmospheric nitrogen in the soil. A pioneer tree on disturbed sites. Considered invasive due to abundant seed production.
