There are many choices of flowering plants that survive the high night temperatures, heavy rainfall and relatively high humidity that is our climate. Here are a few: Tickseed, Coreopsis, spp., Lily of the Nile, Agapanthus africanus, Milkweed, Asclepias, spp., Flax Lily, Dianella, spp., Blanket Flower, Gaillardia pulchella, and Heliconia, Heliconia spp., but there are many, many others.

To insure success, prepare the planting bed by adding some organic material, such as compost, and a slow release, complete fertilizer. Turn it under to a depth of about 6 inches and then you are ready to plant. Dig holes as deep as the root ball and add water, as you refill the hole after putting in the plant,. Allow adequate space between plants for good air circulation, reducing the incidence of fungal and insect problems. Water daily for about a week, if you don’t get rain, then taper off. Mulch the bed well to conserve moisture and suppress weeds. Remember to keep mulch away from the plant stems.

Monitor or scout weekly for insects and diseases so that you can treat early. Removing infected leaves or spraying with insecticidal soap or Neem oil will usually control these problems, if caught early enough. You can reduce the incidence of fungal diseases by using drip or micro-irrigation to keep water off of leaves. Also, water in the early morning, so that leaves dry off by midday.
