As you drive along the highway look out the window at the blooming roadside wildflowers. Fall is the season of yellow and purple, with splashes of red.
St. John’s Wort (Hypericum spp.), many different “daisies” (Aster spp.), tall and short Goldenrod (Solidago spp.), and “sunflowers” (Helianthus spp.) brighten up the landscape with the many shades of yellow. Spikes of Blazing Star (Liatris spp.), clumps of False Rosemary (Conradina canescens), and carpets of Moss Verbena (Verbena tenuisecta) add the purple hues. Here and there clusters of Red Basil (Calamintha coccinea) grab your attention with their fiery color.
Scarlet calamint, also called Red Basil, with its brilliant red flowers, offer a dramatic contract against the backdrop of scrub, sandhill and coastal dunes where the plant naturally occurs in Florida. They bloom sporadically throughout the year, peaking in the fall with as many as 100 flowers on a single plant. It is the only Florida native Calamintha species with red flowers, and its flowers are the largest.

When the Spanish Explorer Juan Ponce de Leon landed on the eastern shores in 1513 he immediately noticed the vast wealth of wildflowers and promptly name his new discovery the “Land of Flowers”, which is the translation for Florida. Habitats throughout the state vary greatly. Changes in elevation by only a few inches can change the soil and impact the types of plants growing there. Associated birds, butterflies, and other pollinators change as the wildflower species vary. Florida has one of the highest biodiversity in the United States.
Learning to identify the roadside wildflowers is the topic of the next Okaloosa County Master Gardener Lecture Series. Join Dave Gordon on Monday, October 23 at the Okaloosa County Extension 3098 Airport Rd. Crestview, FL 32539 from 10 -11 am CDT to learn about what is blooming along the road right of way and how they may be utilized in the landscape. For more information go to:

When beautyberries start producing their eye-catching, bright purple fruit in late summer, we start to get lots of questions. People want to know what it is, where can they find it, and can they eat it? While the berries look good enough to eat, it’s best to leave them to the birds and deer. They are not toxic and were used by Native Americans for a root tea to treat fevers, stomach aches, malaria, and more, but the taste has been described as bitter and mealy. Thanks to a generous volunteer, I am lucky enough to have tried beautyberry jelly. A little (or a lot) of sugar can make most anything taste good—and the finished product is a beautiful, translucent shade of fuchsia.

Even more interesting to me was the revelation that researchers have been able to extract compounds from beautyberry that successfully repel pest insects such as ticks and mosquitoes. The study began about 15 years ago, after a Mississippi botanist with the USDA Agricultural Research Service mentioned to a colleague that his grandfather taught him to rub the crushed leaves of beautyberry on his skin. The technique had been used as a home remedy to prevent mosquito bites for people (and horses) for generations. As a follow up experiment, another group of researchers found these same compounds—callicarpenal and intermedeol—successfully repelled black-legged ticks (which transmit Lyme disease) as effectively as DEET. In the last few years, researchers out of Mississippi have worked towards creating natural insect repellents from the compound that are less harsh on human skin that many commercially available brands.

Aside from its many practical uses, Callicarpa americana is a beautiful native shrub. It has wide green leaves and the brilliant purple berries grow in clusters along its stem. They stay on through late fall and winter in some places, making a beautiful contrast to fall foliage. Beautyberry shrubs can be found in a wide variety of habitats, including sandy and wet soils, full sun, and part shade. Their adaptability makes them a great plant for tight conditions like roadsides or yard edges, but also for nearly any home landscape. The plants can grow to a height of 4-8 feet and spread 3-6 feet wide. The long-lasting berries make them a great wildlife food source later in the cool season than many berry-producing species.

Hurricane Idalia recently tore through the Big Bend area, battering the coast and taking down trees, leaving thousands out of power. While much of the panhandle was safe from the strong winds and storm surge, we still got some gusty weather, and likely had some amount of cleanup to do following the storm. Fortunately for us, this time, it’s mostly a lot of small branches and leaves versus entire trees that our fellow gardeners are cleaning up to the east of us. In addition to being thankful that larger branches didn’t fall here, consider turning those small bits and pieces over to wildlife while collecting your wheelbarrow loads of debris. This is a great opportunity to practice sustainable landscape practices and a few Florida-Friendly Landscaping Principles.
The UF/IFAS Florida-Friendly Landscaping Program has nine principles that it encourages Florida homeowners to practice in their landscape to conserves Florida’s natural resources. Three of the nine principles can be practiced by choosing how you manage the debris that has fallen – #4 Mulch, #5 Attract Wildlife, and #7 Recycle Yard Waste.

The first reaction when looking out at your landscape after a storm is typically “Ugh, there’s a lot of stuff to clean up.” We often want to “clean it up” and get it back to a sea of perfect cut grass, or at least sort of nice grass. However, the small branches and leaves that fall can be a great resource for wildlife, can provide mulch around a tree, and letting them rest reduces the need for you to haul all that stuff up to the road and all that goes into picking up, transporting, and processing the material.
The larger branches (four to six inches in diameter and larger) can be used for firewood or a naturalistic bed edging. Otherwise, they can go into a large brushpile. Smaller sticks and branches are perfect for one large brushpile, or, if a large pile doesn’t meet your aesthetic desires, a series of small piles scattered or hidden behind some shrubs is a good compromise. The leaves and really small stuff (branches no larger than a pencil) can be raked up for mulch, added to the brushpile(s), or just left in place to naturally rot away and/or get shredded up by the mower.

No matter how you leave the debris, consider how important this material is for all sorts of wildlife. Dead wood supports microbes, fungi, and animals up and down the food chain and even adds to your soil organic matter. While it may not look “clean” to us, those bits of “trash” are gold to many critters, especially small insects that bring birds to the yard. So, during cleanup, consider leaving little treats here and there for wildlife and spend less time hauling it to the road!

The plants you bring home from garden centers and nurseries may look beautiful in your landscape, but they might be invasive species that could escape your yard and quickly spread into natural areas, becoming an ecological and economic nightmare. Florida’s climate makes a cozy environment for a variety of plant species, including the non-native ones. To avoid contributing to the problem, homeowners, landscapers, and plant lovers should carefully select alternative sterile cultivars or other native plants.
The Florida Exotic Pest Plant Council (FLEPPC) created a list of invasive plants that was published every two years through 2019. Professional botanists and others perform exhaustive studies to determine invasive plants that should be placed on the lists. Invasive plants are termed Category I invasives when they are altering native plant communities by displacing native species, changing community structures or ecological functions, or hybridizing with natives.
In 2020 the Florida Invasive Species Council (FISC) took over this task. They began by standardizing invasive species terminology. FISC has adopted the following definitions as described in the publication “Invasive Species Terminology: Standardizing for Stakeholder Education” from the Journal of Extension (Iannone et al. 2020). For details on the new terminology go to: https://floridainvasivespecies.org/definitions.cfm. Words like “exotic”, “alien”, and “naturalized” have been removed from educational material due to individual interpretation concerns. The term “invasive” can only be applied to nonnative species. Many previous informational publications referred to aggressively growing native plants as invasive. This use is no longer accepted. Here are some sample definitions:
Invasive: A species that (a) is nonnative to a specified geographic area, (b) was introduced by humans (intentionally or unintentionally), and (c) does or can cause environmental or economic harm or harm to humans.
Nuisance: An individual or group of individuals of a species that causes management issues or property damage, presents a threat to public safety, or is an annoyance. Can apply to both native and nonnative species.
