Venus flytraps grow naturally in the United States in coastal areas of South Carolina and North Carolina that are in USDA Hardiness Zones 7b and 8a. Introduced populations of the insect-eating plant are located in bogs on the New Jersey pine barrens and the Florida panhandle.
Venus flytraps grow well in areas that have understories, which are sandy bogs beneath forest canopies in coastal areas. Fires generally keep understory areas open, freeing up competing brush. These plants grow in nutrient-poor, acidic and moist soil. Fires that usually deprive areas of nitrogen have no effect on Venus flytraps, which get their nitrogen from the insects they consume.
