Gerber daisies come back every year in tropical climates. They are considered perennials in USDA growing zones 9 to 11. They will also grow in zones 6 to 8, but will die at the first frost -- so in those areas, they are considered annuals.
While they may come back from their roots, they also might not, so they benefit from winter protection. Gerbera daisies are considered to be perennials in U.S. Department of Agriculture plant hardiness zones 8 through 10, tender perennials in zone 7 and annuals in lower zones.
