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 biggest problem folks have with flowering potted plants in the heat of summer is remembering that they need water, lots of it. One way to work around having to remember to water every single day is to plant something that doesn’t like too much water but still can churn out a great daily flower show. For this job, there’s only one choice, Purslane (Portulaca oleracea).
Purslane is a super showy, low-growing, succulent-type annual that loves it hot and a little on the dry side. If planted in the ground, it will form a 6-8” tall flowering carpet over the surface of the soil, but I think it really shines when allowed to fill and then spill over the sides of a container! Individual purslane flowers close shop for the day in late afternoon, but cheerily pop back open as soon as day breaks the following day. For best results, make sure the container you plant in has ample drainage holes in the bottom and fill with a quality, quick-draining potting mix. After planting, top dress with a slow-release fertilizer according to the label rate and water only when the soil begins to dry out (every other day or so, generally). Plant a Purslane today!
There are many considerations to make when landscaping with small trees (under 20 feet) in the landscape that are not suitable for large trees. Some of the trees discussed can at times be considered large shrubs depending on definitions and opinions. For the purpose of this article, if it reaches 15 to 20 feet consider it a tree.
Choosing small trees for the right setting involves a number of reasons that could include the need for more privacy from other homes, use as a sound barrier from busy roads, hiding your utility area of the landscape or something unattractive nearby and making sure power lines are not obstructed. Other considerations might include soil types, drainage and holding capacity of the soils, irrigation needs, rate of plant growth and maturity height at 20 feet. Below are a few to consider for the Panhandle of Florida.
Little Gem Magnolia (Magnolia grandiflora ‘Little Gem’) and Teddy Bear Magnolia (M. grandiflora ‘Teddy Bear’) are strong hardy plants once established (within the first 6 months to a year). Both are evergreen with dark green foliage. The ‘Little Gem’ will grow to 20 feet tall by 15 to 18 feet wide. As it matures it tends to become more open and less dense which adds a nice character to show parts of the lower limbs. The ‘Teddy Bear’ will grow to 18 to 20 feet tall but at an even slower rate of maturity to 12 to 15 feet wide while maintaining its density of foliage from bottom to top. It may take a little work to locate the ‘Teddy Bear’ Magnolia.

Several hollies to consider would include the Cassine Holly ‘Tensaw’ (Ilex cassine ‘Tensaw’) and American Holly (Ilex opaca). Both are evergreen and produce red berries during the fall that are bird favorites. They have similar heights of 15 to 20 feet and widths of 10 to 12 feet. Pruning can assist in shaping and slowing these measurements, but keep in mind this will change the look of the tree and create a more formal plant presentation.

The Fringe Tree (Chionanthus virginica) has been a popular tree southeast U.S. for many years. It brings a bright spot to the landscape with white flower panicles that cover the tree in mid to late spring depending on location. For a full color effect, plant it with an evergreen hedge behind it. This oval deciduous tree will grow to 12 to 20 by 10 to 15 wide. The dark blue fruit appears in the fall and serves as good bird food source. This fruit is usually hidden behind the foliage. There might even be a nice yellow leaf change in the fall if temperatures and weather allow.

Spending time gardening in the summer months can be difficult, especially in the Florida Panhandle. The brutally high temperatures and sometimes intensive humidity can make gardening seem unbearable. However, for those brave outdoor enthusiasts, there are always things to do around the homestead when it comes to vegetable gardening, landscape shrubs and lawn care.
Warm season vegetable gardening at this point becomes an uphill battle for some crops, with this being peak time for both insect and disease problems to occur. However, if you planted early enough, much of your harvest is probably in the safe zone. Scouting is key to prevent any major pest damage. Be sure to scout several times a week during these hot, summer days.
Shifting gears, the warm season is a good time to take extra special care of plants such as, azaleas and camellias, while they are establishing flower buds for the next bloom. A lack of water, fertilizer and pest detection and prevention can all certainly play a role in the following season’s flower production. Summer annuals always provide quick and easy color. Remember to feed established annuals with a complete fertilizer and remove faded blooms along the way. Water annuals well during hot, dry periods and control major annual pests to insure good production.
Finally, lawn maintenance is a need for many homeowners during this time of year. Almost all highly successful herbicides are no longer recommended at this point, as many will burn the turfgrass at temperatures above 80 degrees Fahrenheit. Depending on the weed pest and type of turfgrass, most likely the best way to control weeds in your lawn is to wait until cooler fall temperature to treat. Keeping good cultural practices this time of year will help in maintaining a healthy lawn and reduce pest pressure. Be sure to water lawns thoroughly when needed by applying one to three quarters of an inch of water weekly, depending on rainfall. Be sure to keep in mind mower height/frequency, as this is critical in keeping your lawn healthy. As stated in the “Mowing Your Florida Lawn” UF/IFAS EDIS publication, mow often enough so that no more than 1/3 of the blade height is removed per mowing. For example, if your St. Augustinegrass lawn is mowed at a height of 4 inches, it should be mowed before it grows to a height above 6 inches. It is important to always leave as much leaf surface as possible so that photosynthesis can occur, particularly in a grass that is subject to environmental or site stresses.
Unfortunately, it is chinch bug time again. Chinch bugs are prone to feed on St. Augustine lawns during hot, dry weather and may cause serious damage if not controlled. Damage usually occurs as a patch with a brown, dead center and yellowish margin. It seems chinch bugs get the blame, and often unjustly, for everything. Consult with your local county extension office to be sure the damage is not due to other reasons.
For more information, please contact your local county extension office.
