Butterflies seek out plants such as milkweed (Asclepias spp.), passion vine (Passiflora spp.), and Cassia (Senna spp.) to lay their eggs on. There are many native species that act as larval hosts for Florida's butterflies.
Plant least three species for each season - Spring, Summer & Fall. Plus, provide some winter blooming vines, shrubs, trees, or groundcover.
Choose a variety of flower shapes & colors. Clump multiple plants of the same species together to make it easier for pollinators. Ideally, build up to 15-25 species for bee & butterfly diversity.
