Do any of the leaves change color down here in the fall? The most common answer is that there is none here in the land of evergreens. The prevalence of oaks (Quercus spp.) and pines (Pinus spp.) see to that. There is hope. Deciduous trees put on a show as the need for photosynthesis reduces. Chlorophyll production stops replaced with anthocyanins and carotenoids. As they take over, the beautiful display we all love begins. Several tree species thrive in the panhandle and have great autumn foliage. Once you know which, you’ll see a color pallet that would make DaVinci himself drool.
Tree for all seasons
Sweet gum (Liquidambar styraciflua) is a larger tree growing upwards of 75 feet tall with a 50 foot spread. The canopy has an early conical shape which evolves into an oval as the tree ages. This tree is excellent for local parks and to provide shade in your front yard. Red tinged flowers produced in spring combined with multi-shaded leaves provide interest throughout the year. However, autumn this tree comes into its own. As the days shorten and cool these leaves begin their journey to the ground by taking on shades of yellow, orange, red, or burgundy.

Panhandle Delight
A unique tree growing primarily in the Panhandle, the Florida maple (Acer floridanum) puts on an excellent autumn show. At that time of year, the leaves will change to a muted yellow or orange color. Reaching 60 feet high and 30 wide this oval canopied tree is ideal for shade or along streets. Fall is the only time you will see color changes from this tree, but in summer you’ll be treated to that classic maple leaf shape.

An Oddity of a Tree
The bald cypress (Taxodium distichum) is a tree rife with oddity. Growing at times as high as 80 feet with a roughly 35 foot spread these trees excel in your lawn. Be wary as when grown in wet environments they develop “knees” thought to help aerate roots in standing water. Ball shaped cones are the primary reproductive organs of this tree. For the purposes of this article, we’ll focus on the color changing needles. When winter is nigh, they change from pale green to an eye catching yellow or rusty copper. One of the few deciduous conifers, the needles will fall off revealing peeled bark for winter interest.

To Sum it Up
These are but a few of the trees in north Florida known to change color in the autumn. The list is not overly exhaustive, but there are several in this category. For more information on landscape trees, see this Ask IFAS document, or contact your local extension agent for additional information on this and any topic regarding your gardens and more.
Lately, to survive in Panhandle landscapes, plants must be able to tolerate extremes. Summertime temperatures over 100 degrees F, hurricane force winds up to 150 mph, deluges of 1’ of rain in a single day, spring and fall month-long droughts, and the wild winter weather swings we’re experiencing right now. That’s quite a tall order for most plants to bear, however one of our best native trees handles all of the above conditions with relative ease, the stately Bald Cypress (Taxodium distichum). Though Bald Cypress primarily inhabits flatwood “dome” swamps and areas along the periodically flooded edges of waterways and other wetlands and most folks think of it as just “water tree”, the species is more than capable of handling anything Florida’s climate can throw at it, including thriving in home landscapes.

While there are lots of pretty trees in the Panhandle’s natural areas, not many of them possess the longevity, adaptability and well-behaved nature that makes Bald Cypress a great landscape tree. Bald Cypress are capable of living for hundreds of years and grow steadily to a normal landscape height of 50-60’, truly perfect for a specimen shade tree. The species also possesses a strong, wide spreading root system and a special above ground root adaptation, known colloquially as “knees”, that enable Cypress to reach deep to outlast droughts, grow unfazed even when the water rises, inhabit many different soil types, and resist hurricane force winds. While some homeowners object to the presence of Cypress knees in their yard, as the above ground structures can damage mower blades and make for uneven terrain, I’ve found an easy solution is to simply keep the area under the tree’s canopy mulched and forgo mowing there altogether. It looks nice and means less grass to cut!
Bald Cypress isn’t just a big, tough, adaptable tree, it’s also gorgeous. The bright green, finely cut, featherlike leaves give the trees an airy appearance in the spring and summer, nicely offsetting common coarse textured yard trees like Magnolia, Sycamore, Red Maple, and others. However, it is in the fall and winter when Bald Cypress really shines. Though Florida is not known for its fall foliage, Cypress is a notable exception! When the weather gets cool, Bald Cypress leaves transition from green to a yellowish orange before finally arriving at a beautifully unique, rusty, orange-brown color. There isn’t another species out there with a similar show. The foliage holds deep into winter before finally falling to reveal the attractive branching structure, sweeping buttressed lower trunk, and peely gray bark underneath, completing the four-season show.

In addition to being a near perfect landscape tree, Bald Cypress embodies much of what folks admire about life in the South, living the slow life near the water and enduring everything that’s thrown at it with grace and strength. Other than possibly the Live Oak, Bald Cypress is the tree that comes to mind first when I think about the tree that most represents where we come from. From their majestic, buttressed trunks, to the Spanish Moss that hangs loose from their limbs, to the slow, dark water than meanders nearby, the species is iconically Southern. When looking for an impossibly tough, adaptable, and attractive tree, one could do a whole lot worse than Bald Cypress.
If you have any questions about Bald Cypress, other landscape tree options, or any horticultural topic, please reach out to your local UF/IFAS County Extension Office. Happy gardening!

Bald cypress Taxodium distichum is a native tree that is commonly planted in landscapes because it is adaptable to many sites and grows quickly. It is an interesting tree because it has soft flat leaves that fall off in the winter like other deciduous shade trees; however, it belongs to the Cypress family which consists mostly of needled evergreens.
Like the other cypresses, bald cypress produces cones in the fall, which is a primary means of reproduction for the species in natural settings. During the same season that cones are maturing, you might also see what looks like cones forming at the tips of branches among the leaflets rather than along the stem. These mysterious growths are not cones but rather twig galls.
Bald cypress twig galls are abnormal growths of leaf bud tissue triggered by the attack of the cypress twig gall midge Taxodiomyia cupressiananassa. In late spring, adult midges lay eggs on new leaves of the bald cypress. As the eggs hatch and midge larvae start feeding on the bald cypress leaves the growth of a twig gall is induced. The larvae take advantage of this gall using it for food and shelter throughout the larval stage and into the pupal stage. After pupation, adults emerge from the galls, mate, and females lay an average of 120 eggs over a two-day lifespan as an adult. This first generation lays eggs on mature leaves which starts the cycle again. The galls formed by the second generation of the year fall off and overwinter on the ground.
The galls do not appear to affect the health of trees overall, although the weight of heavily infested branches may cause drooping. There are many natural enemies of the twig cypress gall midge, so applying insecticides are not recommended since they may cause harm to non-target insects. The simplest management option is to collect and destroy the galls in the spring and fall to reduce populations the following season.

Considering planting a tree in your landscape, but not sure what will do well?
Baldcypress, Taxodium distichum, is one tree you should consider for your Florida landscape. This deciduous conifer is native to North America and is suited to a wide variety of situations, even difficult ones!
Baldcypress is found naturally along stream banks and in swampy areas, but also performs well in dry situations once established. Not many trees can tolerate standing water or flooding situations, but baldcypress is well adapted to these tough spots. In areas that flood or remain wet the tree will form “knees” that project out of the ground and add a beautiful feature – just don’t plan to mow in areas where these develop. Not restricted to wet areas, baldcypress also performs well as a street tree or in limited root zone situations such as parking lot islands.
This tough tree has a soft, delicate leaf texture and interesting globular cones that start out green then turn brown as they mature. The foliage is light green through the spring and summer then turns a coppery gold before the needles fall in the winter. The trunk has a reddish color that is also attractive and will grow branches low to the ground, but can easily be maintained with a clear trunk in a street tree form.
Baldcypress will grow in full sun to part shade and is adapted to all soil types except highly alkaline (over 7.5 pH). Sand, loam, clay, or muck can all sustain this native tree. Few pests bother baldcypress, but it can be affected by bagworms and mites. Mature size can be in excess of 100 feet, but trees typically grow 60-80 feet tall in Florida.
