Just about a year ago, a dream team of history and plant nerds assembled around a common goal. The idea was to transform an open, weedy space adjacent to the University of West Florida (UWF) Archaeology Institute into a lush garden. The garden would be unique, however, in its purpose; to showcase native plants important to the wide swath of humanity that has made northwest Florida home for centuries. The plants featured here were to be planted deliberately, demonstrating how human relationships with vegetation over time have made the area habitable.

If you walk on the site today, that idea and initial sketches have been made reality. Concentric circles of gravel, mulch, and grass form the shape of a gopher tortoise shell. The tortoise has spiritual significance to members of the local Muscogee tribe and ecological importance as a keystone species. Within the planted space are native groundcovers, shrubs, and trees that have long provided food, traditional medicine, building materials, and dyes and textiles for clothing. This flora makes human life tolerable in a hot, rainy, often difficult environment.

Illustrated signage designed for the site explains ethnobotanical principles, highlighting the relationship that people have had with fifteen plants as they provided healing, nourishment, or protection over the years. The plants are identified on signage in Latin binomial, English common names, and Muscogee language. At the center of the garden is a gravel rectangular space, highlighted by a large piece of local iron rock that represents the tribal Sacred Fire.
One featured plant includes the yaupon holly (Ilex vomitoria), whose leaves are brewed as a highly caffeinated tea. The tea is used ceremonially by many southeastern American Indian tribes, and was popular with early American settlers when tea was difficult to import. Yaupon tea is experiencing a bit of a popular resurgence, with commercial products readily available now. Known as the “black drink,” we all drank a cup of the tasty beverage as part of the open house and ceremonial blessing of the garden a few weeks ago.

The design team developed a scavenger hunt for youth visitors and is working on a self-guided tour to educate the public about native plants, their cultural heritage, and their role in supporting a healthy watershed. The garden is open to the public during daytime hours, and located near the entrance to UWF at the eastern corner of University Parkway and Campus Drive.
Habitat, whether for wildlife or people, relies on the provision of food, water, shelter, and space. All these needs are met within the UWF Heritage Roots Garden. We hope that visitors will develop a deeper appreciation of the region’s historical and ecological legacy, strengthening modern cultural connections with the past. We hope to tie in the Heritage Garden to other UWF campus garden spaces, including the Edward Ball Nature Trail and the UWF Community Garden.
Many gardeners enjoy plants that attract butterflies and there is no shortage of beautiful flowering plants to supply nectar for all our pollinators. One critical part of making habitat for butterflies that we may need to improve upon is supplying plenty of host plants for butterfly development. While we enjoy the flight of a butterfly through our garden, we really want to offer features that keeps them around.
Your landscape likely includes a few host plants and maybe you even have a citrus tree or plant parsley every season. What many people don’t realize is how many native trees serve as host plants for butterflies. Some of these plants like specific environments while others can grow in a wide variety of habitats.
The Black cherry (Prunus serotina) and Cherry laurel (Prunus caroliniana) serve as host to a large number of butterflies. A more well know species that uses the native cherries for development is the Tiger swallowtail. Although we might consider these trees weedy, they can serve as hosts to hundreds of species of butterflies and moths along with providing berries for wildlife. The black cherry will be deciduous while the cherry laurel is evergreen. Both have flowers in late winter or early spring. Just be aware that the cherry laurel fruit can have some toxicity in different developmental stages.

The Winged elm (Ulmus alata) is gaining in popularity as a landscape tree. The Question mark butterfly will lay eggs on plants under the elm and then caterpillars crawl up to feed on elm leaves. The reason we don’t see this butterfly on flowers as much is that it also feeds on manures, carrion, and rotting fruit. Resting butterflies have wing patterns that make them look like leaves.
If you have a site with moist soil or can supply routine moisture, consider the Sweet bay magnolia (Magnolia virginiana). It will attract the Tiger, Palamedes, and Spicebush swallowtails for development. Flowers on the tree are not as large as those on Southern magnolia but you still have similar appearance and even a pleasant fragrance.

A couple of understory trees are the Pawpaw (Asimina triloba) and Sparkleberry (Vaccinium arboreum). Look for the Zebra swallowtail to find the Pawpaw while the sparkleberry will serve as host to hairstreak butterflies.
Pawpaw also offers delicious fruit. Photo by Beth Bolles, UF IFAS Extension Escambia County.
Even though landscapes may have limited spaces for every host plant, we can preserve some spaces around borders for native trees. These plants will make a positive impact for butterflies and pollinators.
Sunflowers, Helianthus spp., are a great choice for gardeners who are looking for some cheerful color in their landscape. Here in Florida, we have the main ingredient for success, lots of sunshine!

Sunflowers are short-lived annuals. A good average time between planting and bloom is roughly 65 days. You can typically plant sunflowers in Florida beginning in late winter until early fall. Only the coldest months are the issue, and for most years that’s only a couple of months for us. Sunflowers can be planted almost anywhere there is full sun. The major selling point to plant sunflowers is of course the impressive blooms (figure 1). These yellow to sometimes orange or red petaled flowers develop a central seed disc, with most varieties having approximately an 8” diameter in growth.

As for planting, you may choose to plant narrow rows and close seed spacing in order to cull less preforming plants later. A final row and seed spacing of 2’-3’ is recommended for full height and development of most varieties. However, you may choose to plant in a bed, using a close pattern as seen in figure 2. In any event, sunflowers are easy to propagate by seed and are very low maintenance. However, powdery mildew and spittle bugs can be a nuisance. A general garden fungicide and insecticide will help if problems occur.

Sunflowers are available in many varieties, which consists of different color blooms and plant sizes. These sizes range from dwarf (1’-3’) to tall (10’-15’) varieties (figure 2). You may wish to stake taller varieties at some point, as some plants will tend to lean with no wind break in place. Here’s a few gardening variety common names to look for: sunbright, sonja, sunrich lemon or orange and autumn beauty. Seed companies also have mixes available in packets. For tall plants, mammoth or skyscraper varieties exist.

If you are fond of the sunflower bloom and looking for a groundcover, there are a couple of native perennials that fit this category. Beach sunflower, Helianthus debilis or swamp sunflower, Helianthus angustifolius, are groundcovers/ornamentals for landscapes and thrive in dry, hot climates and in a range of soil types. They also are great pollinator attractors.

Black-eyed Susan, Rudbeckia hirta, is a yellow wildflower commonly found throughout Florida. It is easily recognized by its golden yellow petals and dark brown center or its signature “black eye”. Not only is black-eyed Susan a beautiful addition to any landscape or garden, but it is also beneficial to pollinators and easy to care for! A win, win for gardeners alike!
As a native wildflower to much of the eastern and central United States, Black-eyed Susan plays an important role in supporting local ecosystems. It provides pollen and nectar to a wide variety of pollinators such as native bees, butterflies, hoverflies, and other beneficial insects. Its long blooming season provides a food source to support these species during the hot summer months when many other plants are not blooming.
One of the greatest appeals of Black-eyed Susan is its versatility. It can be grown in full sun and well-drained soil but will tolerate poor soil, drought and even some shade. After establishment, it requires minimal care and returns each year.
Growing Considerations:
USDA Hardiness Zones 2-11
Soil pH range: 6.0-7.2
Soil tolerances: clay; sand; acidic; loam
Plant spacing: 12 – 28 inches
Moderate drought tolerance
Flowering months: May – October
Growth height: 1-3 feet
If you’re looking for a resilient, beautiful, pollinator-friendly flower that brings bold color during the summer and is easy to care for, Black-eyed Susan is a great option!
Beach sunflower is an attractive coastal plant that is well suited for many landscapes. The native plant can thrive in hot and dry spots where other plants may struggle. Learn more about Beach sunflower, Helianthus debilis, and how to use it in your landscape.
It’s that time of year when you bump into a bumble bee and watch butterflies fluttering around as you water the garden. If you’re like me, you’ve been waiting patiently for butterflies to start laying their eggs. Butterflies and moths lay eggs on specialized plants that caterpillars depend on once they hatch. These host plants provide caterpillars with food, shelter, and protection- and they can be anything from a small weed to a tall oak tree.

While host plants feed caterpillars, nectar plants feed butterflies. Host plants are specific to each butterfly or moth, while nectar plants attract and feed many different species. Provide a variety of shapes, sizes, and colors of flowering plants to attract different butterflies. To support all life stages of butterflies it’s important to have both host and nectar plants in your garden.
Keep an eye out for signs of caterpillars on your host plants and remember that these plants are meant to be eaten! Because caterpillars feed exclusively on their host plants, they won’t harm the rest of your landscape. Before you reach for pesticides when you see leaf damage, take a moment to identify what’s causing it. It may just be hungry caterpillars getting ready to transform into butterflies. For more information see this EDIS publication about butterfly gardening in Florida, https://edis.ifas.ufl.edu/publication/UW057.

Want to support both caterpillars and butterflies with one plant? Try passionflower! Florida is home to 6 native species of passionflower. Maypop or wild passionflower, Passiflora incarnata, is the showiest of these. Flowers of pink and purple cover the passionflower from the summer to fall, offering nectar for bees, butterflies and hummingbirds. Passiflora species are host plants for the zebra longwing and gulf fritillary caterpillars.
