Uses
Swamp Cabbage
CulinaryThe terminal bud (heart) is edible when cooked and was traditionally eaten by Native Americans and settlers. It has a mild flavor similar to cabbage and can be boiled, fried, or used in salads, though harvesting kills the tree. [source]
Frond Fiber Products
HouseholdDead fronds have been historically woven into baskets, fans, and thatching materials. Modern craft uses include dried frond arrangements and sustainable fiber products. [source]
Wildlife Habitat and Food
WildlifeThe tree provides shelter for cavity-nesting birds and other wildlife. Black fruits attract birds and wildlife in fall; flowers provide nectar for insects and pollinators. [source]
Ornamental Landscaping
HouseholdWidely used as an iconic landscape tree in southeastern U.S. gardens, street plantings, and coastal properties due to its attractive form, salt tolerance, and low maintenance once established. [source]
Traditional Uses
MedicinalHistorically used in traditional medicine by indigenous peoples for various ailments, though modern scientific evidence is limited. Fruit extracts have been studied for potential health properties. [source]

Harvest Tips
Harvest hearts (terminal buds) by cutting the trunk below the bud; this kills the tree, so only harvest from mature specimens or dedicated plantations. Heart is best harvested in spring. Fruits can be collected when black and fully ripe in fall. Seeds can be collected and cleaned for propagation.
