Yaupon hollies, Ilex spp., are a native plant to Florida that grow very well and abundantly in our local soils. The yaupon holly is one of the hardiest holly species found in Florida. You may see this holly grown as a tree, large or small specimen shrub, or even as a hedge. Using a low-input native plant like yaupon in the landscape can result in less nutrient pollution, reduced water use and resilience through drought, freezes, and hurricanes. This plant thrives in the southeast and is hardy up to USDA zone 7. They can even tolerate temperatures as low as 10F for short periods of time. Pollinators are also attracted to the yaupon flowers – if you are trying to attract bees for other crops on the farm, this is the plant for you! Growing yaupon is much easier than other crops because the species can handle a variety of conditions, from full sun to light shade and soil from dry to wet. Growth rate is moderate when they are young and slows as plants age. Yaupon hollies are good for stabilizing the soil, preventing erosion, and providing a habitat for wildlife.
Yaupon is a very old plant that historically has been used as an important food source, medicine and even a ceremonial item by Timucua Indigenous groups for thousands of years. The Timucua people of Florida believed that yaupon purified the mind and body of those who drank it. Yaupon is the only naturally caffeinated plant species grown in the United States. It provides a balanced caffeine boost without the bitter tannins that you get from regular tea. Yaupon contains 30% less caffeine than coffee but provides a dose of theophylline and theobromine. These 2 compounds provide an energy that will not cause jitteriness and caffeine crash that other caffeinated beverages can give you. There are also dozens of vitamins, minerals, amino acids, polyphenols and antioxidants to protect the body, and these can help calm the mind as well.
‘Schilling’s Dwarf’ is a yaupon cultivar perfect for homemade tea production. The plant gets no taller than four feet and four feet wide. While you can make yaupon tea from any yaupon holly cultivar, all ‘Schilling’s Dwarf’ clones are also all male, which means no berries will get in your way of harvesting leaves. To prepare tea from the yaupon plant, leaves are removed from the stems and lightly washed, discarding any berries and debris. The stems may also be used and will not change the flavor. Next you will dehydrate leaves and stems by air or sun drying. Leaves can be stored whole or crushed and blended into smaller pieces if desired. These leaves produce a caffeinated beverage that is similar to green tea with grassy flavors. If these same leaves are lightly roasted, over a hot pan or in the oven, it will produce an earthier beverage that can have notes of malt and toasted coffee.

The mucky, sunny spaces here in northwest Florida are inevitably full of beauty and surprises. Due to the sopping wet, acidic, and nutrient poor soil, plants in these areas must make some unusual adaptations. Wetland bogs are home to several interesting and carnivorous species, like pitcher plants and sundews. Most sundew species I come across are the tiny, pinwheel shaped dwarf sundews (Drosera brevifolia), which lie prone to the ground.
At a recent visit to the Roy Hyatt Environmental Center, I noticed a showy purple flower that at first I assumed was a meadow beauty.

Lavender, four-petaled meadow beauty flowers are common in wet areas. However, this plant was a bit different. First, it had five petals; but even more unusual was that something akin to a green caterpillar was hanging from every flower bloom. Intrigued, I bent closer and saw that the green segments were not a dangling invertebrate, but a series of fuzzy green flower buds. The bud closest to the purple flower was a deep violet and close to flowering.

In all my years of exploring and leading people around pitcher plant prairies, I’ve encountered Tracy’s sundew/threadleaf sundew (Drosera tracyi)—a type of sundew with an upright, sap-covered stem—but never one in bloom.

Typically, you’ll only come across the slender, threadlike ( a structure known as “filiform”) fiddlehead leaves. These leaves look more like stems, and are bright green and covered in dewy, sticky, deadly-to-insects droplets. Insects are attracted to the shimmering drops of mucus, triggering a hormone in the plant that causes the leaf and its glands to fold over the prey. Once stuck, the insects suffocate and are digested by enzymes in the leaf glands.
The purple flowers appear in May or June, atop a single leafless stem that appears unattached to the threadleaf sundew leaves. According to the Georgia Biodiversity Portal, this series of flowers will “open one by one, from the bottom of a coiled inflorescence up, with unopened buds at the top. Flowers begin to open about 9:00 am and close about five hours later; some flowers persist for two days.” Threadleaf sundews can self-pollinate but are also attractive to bees.

Native azaleas are stunning this time of year. These deciduous shrubs (and sometimes small trees) often go unnoticed until they bloom in the spring. Three species native to Florida are the piedmont azalea (Rhododendroncanescens), the Florida flame azalea (Rhododendron austrinum), and the swamp azalea (Rhododendron viscosum). Piedmont azaleas have whitish to pinkish blooms, Florida flame azaleas have yellow to orange blooms, and the white blooms. All three species have a wonderful honeysuckle-like, sweet fragrance. All three serve as outstanding focal points in the landscape.
Native azaleas and other deciduous azaleas have varying site preferences. Like other azaleas, piedmont and Florida flame azaleas prefer moist, well-drained, acidic soils. However, as the name would suggest, the swamp azalea tolerates wetter locations. All three species prefer partial shade (morning sun and afternoon shade are best) locations and can grow up to 15 feet tall.

In addition to these beautiful native azaleas, a number of deciduous hybrids have been developed. Aromi hybrids have been bred to tolerate heat and humidity. These azaleas were developed from four native species ()from Gene Aromi in Mobile, AL. He developed more than 100 cultivated varieties (also referred to as cultivars). Popular cultivars in the market include ‘Centerpiece’, ‘Aromi Sunrise’, and ‘Aromi Sunny-Side-Up’.
Deciduous azaleas do not require a lot of fertilizer. A controlled release or slow release, acid forming (specifically formulated for azaleas or blueberries) fertilizer is recommended. A fertilizer nutrient ratio of or close to 2-1-1 (N-P-K) should be selected. Plants should be fertilized in spring or early summer, never in the fall or winter.
Many of the native plants in the Northwest Panhandle of Florida are often placed into landscapes as backdrop support plants. Many bring the solid green color to emphasis other colorful plants. What is often missed is the opportunity to see the fall color palate of these plants. Sometimes the easiest thing to do is travel to the nearest nursery to purchase annuals and perennials that come from all over the world and have been time tested to determine their invasiveness outside of planting areas and are determined to be at a minimal risk of colonizing outside of their intended planting area.
Native plants may not be in the thought process and are often overlooked for their exceptional color that can be a focal point in the landscape. Several native plants bring multi-colored leaves or flowers adding fall interest for all to enjoy. Let us take a moment and look at just a few of the plants that can be found in the Florida Panhandle that offer the many colors you may be looking to utilize in your landscape.

American Beautyberry
Beautyberry has two wonderful display times each year. In the late spring to early summer petite light colored lavender flowers open in small clusters along the upright stems of the plant. This flowering can be a brief soft show for a few weeks. The big color show comes in the fall with colorful shiny purple fruit clusters known as drupes. The fruit clusters around the stems of the plant in groups of 20 plus drupes. Often you will see multiple clusters on a given stem spaced approximately 3 to 4 inches apart in the beside the leaf petiole area.

Blazing Star
Blazing star is another fall beauty that creates a great vertical flower floret display of tall spires showing a pleasant medium lavender color. The clustered small flowers provide color in the garden for several weeks. This pollinator plant attacks Monarchs and Swallowtails butterflies plus others adding more enjoyment to the garden. For quality establishment and growth, it needs well drained soil, yet soils that are not high in fertility. Overly fertile soils will over stimulate flower stem growth that will grow too tall and flop over. Blazing star can be divided once it is established and has expanded through underground stem growth creating a wider plant base. In sandy soil sites that have been disturbed through clearing this plant will often establish through seed from adjacent plant settings.

Golden Rod
One of the stronger colors of fall is yellow and the native Golden Rod is a big contributor with its upright stems holding multi-clusters of small bright yellow blooms. This plant serves as a pollinator plant for butterflies, bees and other beneficial insects. Often associated with fall allergies, this plant is not likely the culprit as the pollen is heavy and does not blow on the wind as ragweed will do. Ragweed blooms around the same time and does not have a showy bloom, yet many suffer from allergic reactions to this plant making it the likely problem plant for allergy sufferers. Golden Rod tends to colonize and crowd out other native plants so don’t hesitate to thin out the plant area if it is expanding too quickly.
Growing native plants including fall flowering selections is a fun journey for all to enjoy as the cool hints of fall weather moves in. Do a little research and keep in mind there is an Extension office in every county to assist in addressing your gardening needs.
Invasive species are all around us, from invasive plants like cogongrass to invasive amphibians like Cuban tree frogs to invasive insects like red imported fire ants. These species affect our ecosystems by outcompeting native species for nutrients or food and other precious resources. To help with the management of these noxious organisms, the October 2021 edition of Gardening in the Panhandle LIVE educated the public on invasive species. The highlights from the webinar are listed below.
