USDA Zones: 3-8A [3]

Maximum age: Lives to a maximum age of 125 years [4].

Ecology: Though they are now eaten by deer, opposums, raccoons, birds, and small mammals [1,2,4], the leathery, pulpy seed pods once attracted extinct megafauna such as mammoths and giant sloths [6]. Both deer and livestock browse the foliage [1,2,4]. Pollinating insects, including bees, frequent its flowers [1,4]. 

Ethnobotany: The wood is dense and can be a valuable source of building materials [1,2,4]. Indigenous Americans use the seed pulp as a sweetener, and the seeds can be roasted and used as a coffee substitute or ground into flour [1,2,4,5].
