Winter is when many Florida plants become dormant and lose their leaves until spring. In contrast, most of our ferns remain a vibrant green through the winter. This is in part because ferns are plants that live in moist environments and the water buffers them from the cold. A winter visit to a marsh, swamp, or other wetland can be refreshing on a cold winter day in south Florida. While other plants lose their leaves, ferns generally have a more intimate contact with their wet environment. Fern diversity in wet areas can be spectacular – each species occupying a somewhat unique niche, thus minimizing competition with other species.
