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?

There are many annual and perennial flowers that will grow in your area.

Several species of native iris and the native Louisiana
iris and their hybrids do well in Florida. The German
and Japanese varieties do not grow well in our hot,
humid climate.

Iris rhizomes should be planted in late summer or fall.
Plant rhizomes 1" deep and space 8" apart. Plant in
semi-shade. Add plenty of organic matter to soil at
planting time. Fertilize lightly with a 6-6-6
fertilizer.
Other good perennials for your climate include daylilies, yarrow, coreopsis, gaillardia (blanketflower), gazania, and blazing star (Liatrus). There are many more.
I suggest you contact your County Extension Service and
request a copy of Circular 569 (Annual Flowers for Florida).
The County Extension Office for Jackson County is in
Marianna, telephone number is (850)482-9620. Ask also
about perennials for your area.
