The Q&A Archives: Plants for Hot, Humid Areas

Question: I have a garden in Jackson County, Fl. (in hardiness zone 8-b, just barely). I would like to know what are the best plants to grow in hot humid areas along the Florida coast. I especially like Iris, but I don't know which kinds will grow in those conditions. Can you help me on this?

Answer: There are many annual and perennial flowers that will grow in your area.<br><br>Several species of native iris and the native Louisiana<br>iris and their hybrids do well in Florida. The German<br>and Japanese varieties do not grow well in our hot,<br>humid climate.<br><br>Iris rhizomes should be planted in late summer or fall.<br>Plant rhizomes 1" deep and space 8" apart. Plant in <br>semi-shade. Add plenty of organic matter to soil at<br>planting time. Fertilize lightly with a 6-6-6 <br>fertilizer. <br>Other good perennials for your climate include daylilies, yarrow, coreopsis, gaillardia (blanketflower), gazania, and blazing star (Liatrus). There are many more.<br> I suggest you contact your County Extension Service and<br>request a copy of Circular 569 (Annual Flowers for Florida).<br>The County Extension Office for Jackson County is in <br>Marianna, telephone number is (850)482-9620. Ask also<br>about perennials for your area.
