October is an important month for butterflies. The monarchs are making their epic migration towards Mexico, gracing us with their presence as they stop to feed on saltbush or lantana plants along the coast. But our homegrown orange-and-black butterfly is showing up everywhere right now, too. The Gulf fritillary (Agrautis vanillae) is a smaller species, but also features bright orange wings with black stripes and spots. Their caterpillars come dressed for Halloween, too—they are a deep orange color with black legs and spikes. While the caterpillar is not venomous to any potential predators, the spikes are quite intimidating and serve a protective function.

Fritillary (name from the Latin “chessboard”) eggs are bright yellow and laid primarily on varieties of passionflower vines, which the caterpillars feed voraciously upon. Passion vine is an important host plant for the zebra longwing as well, which is Florida’s state butterfly.
Gulf fritillaries are found in all 67 Florida counties, and may live throughout the southeastern United States, Mexico, and central and south America. They are found in varied habitats but prefer open, sunny spots in fields, forests, and gardens. The butterfly’s wing shape puts them into the “longwing” category, as their elongated wings spread wider than other species.

In the fall, fritillaries migrate to the warmest ends of their range. By spring, they move slightly north into North Carolina or interior Alabama.

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.
