South Florida can get very hot & humid especially during the rainy season of May through September.
Many times great gardeners come here from different climates & have a learning curve as to what works & what does not in an attempt to duplicate their past landscapes.
In Zone 10 you can achieve a beautiful yard whether you want it to be traditional with hedges & trees, tall grasses & exotic flowers such as orchids or bromeliads xeriscaping with succulents & rocks.
A pop of color here and there with hardy plants such as Hibiscus or flowering trees are what make our area so unique.
