Working in Extension has given me a lot of interesting opportunities. On the job, I’ve found myself leading kayak trips all over Florida, building a two-story bat house, and wearing a Mr. Peanut costume while talking about agriculture. But I never really imagined being featured on a home improvement reality TV show. Sure, I’ve watched my fair share of Extreme Makeover: Home Edition and Love it or List it, but those were just entertaining ways to pass the time and maybe get some ideas for my own house.
Then, a few months ago our office was contacted by the producers of a show called Flip My Florida Yard, to inform us they would be in Escambia County to film an episode of the show for the Discover Florida channel. As part of the effort, they’d need a local Extension agent to go on a site visit, help review the landscape design, and talk about Florida friendly landscaping principles on air. Based on my prior experience as a Florida Yards & Neighborhoods agent (and our horticulture agent being swamped with Master Gardener training), I got the reality TV job.

Part education and part entertainment, the show’s premise is similar to most home remodeling shows. A couple or family wishing to improve their current home shares their hopes with the remodelers, the homeowners are sent away for a day, and upon their return they are surprised with a brand-new look.
The twist with Flip My Florida Yard is that the landscapes in need of improvement are redesigned with Florida-friendly principles in mind. During each episode, Extension agents, IFAS researchers, and landscape designers are interviewed about concepts like using mulch and compost, proper irrigation, or “right plant, right place” choices based on soil type and sunlight availability. Last season, the crew was in Panama City to help a family restore their yard after damage from Hurricane Michael. For our Escambia County program, we will focus on appropriate fertilization, managing stormwater, protecting the waterfront, and providing wildlife habitat.
The “Flip My Florida Yard” program features Florida homeowners getting a Florida-friendly landscape renovation. The show is available online and through several streaming services.
In late December I was interviewed by the show’s producers, and we spent a full day renovating a local backyard. The challenging, steeply sloping backyard was given some really nice amenities, including a rain barrel, a seating area, and wildlife attractants. Our local episode should air in March or April. In the meantime, all the past episodes are available for viewing on the Discover Florida Channel. The channel can be accessed via a free online account, or through several streaming services like Roku, Apple TV, and Amazon Fire. Flip My Florida Yard is a creative partnership between the Department of Environmental Protection/Florida State Parks and the state level UF IFAS Extension Florida Friendly Landscaping Program, so even the commercial breaks cover environmentally friendly messages and scenic views of state parks. Check it out—you might get some helpful ideas or even become the next homeowner featured!
Here in Florida, we have snakes. Some may say we have lots of snakes. While their presence may be something to be expected out in wild areas, homeowners often find it alarming when these creatures show up near places where we live. The reaction is often a simple one: if it is a snake, kill it.
Dealing with snakes should not be like this, however. Although some are venomous, many others are harmless to humans and make valuable contributions to the local ecology. As more natural areas become developed, wildlife such as snakes are increasingly pushed into close contact with people, so learning to live with them is important.
Of the 46 species of snakes found in Florida, only 6 are venomous. The chances of being bitten by one of these venomous snakes is very low; there are only 7,000-8,000 bites in the entire U.S. each year. Fatalities are even more rare, with less than ten people typically dying across the country annually from venomous snakebites. In a country with a population of around 330 million, that’s not a lot.

Snakes, especially venomous ones, should be treated with respect, however. Knowing how to identify a snake can be an important step in knowing how to react to them, and understanding their behavior can help avoid unfortunate encounters. The venomous snakes we have in Florida are the copperhead, the coral snake, the cottonmouth or water moccasin, the Eastern diamond-backed rattlesnake, the pygmy rattlesnake, and the timber rattlesnake. For help in identifying these species, see our guide on EDIS at https://edis.ifas.ufl.edu/publication/UW229.

Understanding snake behavior, including their feeding habits and preferred habitats, is also important. If you can make the areas you live in less hospitable to snakes, especially venomous ones, they’ll be less likely to move in. This doesn’t mean getting rid of every snake out there – some snakes that are harmless to humans may be predators that consume other snakes (including venomous ones) or rodents. Because venomous snakes often consume rodents and other small animals, allowing the nonvenomous ones to control populations of prey can help keep dangerous snakes out!
Watch out for areas where snakes may shelter, including tall grass, overgrown shrubs, piles of brush and wood, or debris. There is no need to remove all such things from a property, as other wildlife use them as well, but keep them away from houses and areas where people frequent. Also be sure to keep rodents under control in and around buildings to avoid attracting snakes that feed on them.

The ancient cycad, coontie, is a hardy and attractive plant for Florida landscapes. Photo credit: Carrie Stevenson, UF IFAS Extension
The plant has a crazy-sounding name, more like some little animal you’d find in Australia than a native plant. However, an ancient Florida plant it is, and a tough one at that. Growing close to the ground, it most resembles a large fern or a sago palm, if the sago had smooth, rounded leaf edges. Like the sago, the coontie (Zamia floridana) is a cycad—a group of palmlike plants that have been around so long that triceratops and stegasauruses ate them! Coonties are the only cycads native to North America, found in the states and island nations like Cuba and the Bahamas.

Another interesting feature of the coontie is its seed cones. These are large reddish orange cones that resemble magnolia seedpods. Both sexes of plant produce them in clusters ranging from one to five of the 2-7” long cones. Cones from the male produce pollen, while females produce seeds. If you are interested in attracting wildlife to your yard, the coontie provides good low-growing cover for birds and small mammals. It is also the preferred food for the caterpillar of the rare Atala butterfly. Members of the Timucuan and Calusa tribes ground up the starchy root of the coontie as a flour. However, the root contains a toxin and if it is not removed first, ingestion could result in severe abdominal pain and vomiting. From the late 1880’s through World War I, a large starch industry existed in Florida, producing flour from the coontie root.

At home in drier soil conditions like oak hammocks and pinelands in north central Florida, these plants can also adapt to a variety of soil pH types. Coonties are drought, cold, and salt tolerant, thus a great landscape choice for coastal landscapes near the Gulf or a bay. The plants are very long-lived and adaptable. In fact, the book Florida’s Best Native Landscape Plants notes it is “Very hardy and easy to care for. Will grow well in any part of Florida, even outside its normal range. An exceptional replacement for the closely related, often used, but non-native sago palm.” In other words, this is an ideal landscape plant that should be used more throughout Florida.
Saw palmettos provide crucial ecosystem services for the forests of Florida. Photo credit: Carrie Stevenson, UF IFAS Extension
The saw palmetto (Serenoa repens) is a classic symbol of Florida. Found in upland habitats and just to the edge of wetlands, their brilliant green fronds stand out in the mostly brown pine flatwoods and oak hammocks to which they are endemic. The shrublike saw palmetto thrives in sandy soils, is highly salt tolerant, and is tough as nails. The plant’s root is one of the sturdiest in nature. Imagine the trunk of a palm tree laid horizontally and just underground—this is the plant’s base. This root system lends stability and tolerance to nearly every tough Florida growing condition, including drought, floods, and fire. Saw palmettos are extremely slow growing, and there are stands in south Florida in which botanists have found individual plants and clonal colonies several thousand years old. Saw palmettos are one of the few members of the palm family that thrive in the panhandle. While many palm trees are planted here, most are native to more southern climates with warmer winters and karst geology—a higher pH soil composed of limestone and often prone to springs and sinkholes.

The saw palmetto’s name comes from the serrated, saw-like edges of the stem. These are quite tough and can cut your skin and clothing if not careful. A very similar palmetto, the bluestem, grows in wetter soils. It can be differentiated from the saw palmetto because its stems are smooth—no serrated edges—and the whole plant has a bluish cast to it.
The saw palmetto has long been prized by humans for its practical uses. The “ethnobotanical” history of this plant has ties to Native American tribes who used the fronds for roofing and building material, brooms, fishing nets, and fans. The leaves were utilized for rope, and multiple plant parts for food and medicine. The dark blue/black fruit of the saw palmetto was considered an aphrodisiac and has been used to treat prostate problems for centuries. According to a UF publication on the saw palmetto, “Modern day development of a purified extract from the berries greatly improves symptoms of enlarged prostate. Florida is the biggest source and producer of saw palmetto products. With about 2,000 tons harvested from South Florida and exported to Europe each year, the fruit crop estimate is $50 million a year in the state.”

Besides the human uses, saw palmetto serves as a crucial component in the diet of native wildlife. Florida black bears, panthers, 20 other species of mammals, over 100 types of birds, 25 amphibians, over 60 reptiles, and countless insects depend on saw palmetto berries as part of their diet. The wild harvest of saw palmettos is regulated by the state to prevent overharvesting and negative impacts to the wildlife food supply.
Saw palmettos also make a great home landscape plant, as they can grow in a wide variety of conditions, provide wildlife food and habitat, and add visual interest. There are few plants more “low-maintenance” than an established saw palmetto. A mature one is so difficult to remove, that it’s best to leave it where it is anyway!

Haunting alluvial river bottoms and creek beds across the Deep South, is a highly unusual oak species, Overcup Oak (Quercus lyrata). Unlike nearly any other Oak and most sane people, Overcups occur deep in alluvial swamps and spend most of their lives with their feet wet. Though the species hides out along water’s edge in secluded swamps, it has nevertheless been discovered by the horticultural industry and is becoming one of the favorite species of landscape designers and nurserymen around the South. The reasons for Overcup’s rise are numerous, let’s dive into them.
First, much of the deep South, especially in the Coastal Plain, is dominated by poorly drained flatwoods soils cut through by river systems and dotted with cypress and blackgum ponds. These conditions call for landscape plants that can handle hot, humid air, excess rainfall, and even periodic inundation (standing water). It stands to reason our best tree options for these areas, Sycamore, Bald Cypress, Red Maple, and others, occur naturally in swamps that mimic these conditions. Overcup Oak is one of these hardy species. Overcup goes above and beyond being able to handle a squishy lawn, it is often found inundated for weeks at a time by more than 20’ of water during the spring floods our river systems experience.

The species has even developed an interesting adaptation to allow populations to thrive in flooded seasons. Their acorns, preferred food of many waterfowl, are almost totally covered by a buoyant acorn cap, allowing seeds to float downstream until they hit dry land, thus ensuring the species survives and spreads. While it will not survive perpetual inundation like Cypress and Blackgum, if you have a periodically damp area in your lawn where other species struggle, Overcup will shine.
Overcup Oak is also an exceedingly attractive tree. In youth, the species is extremely uniform, with a straight, stout trunk and rounded “lollipop” canopy. This regular habit is maintained into adulthood, where it becomes a stately tree with a distinctly upturned branching habit, lending itself well to mowers and other traffic underneath without having to worry about hitting low-hanging branches. The large, lustrous green leaves are lyre-shaped if you use your imagination (hence the name, Quercus lyrata) and turn a not-unattractive yellowish brown in fall. Overcups especially shines in the winter, however, when the whitish gray, shaggy bark takes center stage. Overcup bark is very reminiscent of White Oak or Shagbark Hickory and is exceedingly pretty relative to other landscape trees that can be successfully grown here.

Finally, Overcup Oak is among the easiest to grow landscape trees. We have already discussed its ability to tolerate wet soils and our blazing heat and humidity, but Overcups can also tolerate periodic drought, partial shade, and nearly any soil pH. They are long-lived trees and have no known serious pest or disease problems. They transplant easily from standard nursery containers or dug from a field (if it’s a larger specimen), making establishment in the landscape an easy task. In the establishment phase, defined as the first year or two after transplanting, young, transplanted Overcups require only a weekly rain or irrigation event of around 1” (wetter areas may not require any supplemental irrigation) and bi-annual applications of a general purpose fertilizer, 10-10-10 or similar. After that, they are generally on their own without any help!
