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.

Dung Beetles of the Florida Panhandle

There aren’t many creatures that can stir up a mix of admiration – and possibly some mild disgust – like the dung beetle. But if you spend much time around pastures, the woods, or even in your own garden, you might be surprised to learn these literal poop-pushers are the unsung heroes in local ecosystems – especially when it comes to soil health.
Dung beetles, which are primarily members of the Scarabaeidae family, specialize in feeding on and burying animal feces. That might not sound glamorous, but they more than earn their keep in the ecosystem. These beetles break down waste, aerate the soil, recycle nutrients, and reduce parasite loads in pastures. By quickly burying dung, they limit fly breeding and prevent harmful bacteria from hanging around longer than necessary.
In our part of Florida, where livestock, wildlife, and backyard chickens are common, dung beetles can play a quiet but essential role in keeping both landscapes and gardens healthier. While you might not see them directly in your raised beds, the soil health benefits they bring to the wider environment ripple out in ways gardeners can appreciate.

Not all dung beetles are the ball-rolling athletes we imagine. In fact, most species in Florida are what we call tunnelers – they bury dung directly underneath where it lands, creating little underground pockets of fertility. Others are dwellers, who live inside the pile and lay their eggs right there.
While most of our local dung beetles are underground specialists, we do have at least one native species that performs that famous backward march. If you’re out walking after a summer rain, you just might spot a shiny black beetle with spiny legs rolling a dung ball twice its size – just one of the many native species quietly doing their part beneath our feet.
Native Dung Beetles of North Florida
While most people wouldn’t recognize a dung beetle if it landed on their compost pile, a surprising number of native species are hard at work across the Panhandle – from open fields to pine flatwoods to the edges of suburban backyards.

One of the flashiest is the rainbow scarab (Phanaeus vindex), a heavy-bodied tunneler with a brilliant metallic sheen – often green or blue with coppery highlights. Males sport a single, curved horn and are known to spar over fresh dung like tiny armored knights. They’re most active in the warmer months and are common in both wild and grazed areas.
Another native jewel is the fiery scarab (Phanaeus igneus), which also shines with a coppery or red metallic glow. A Florida subspecies, P. igneus floridanus, occurs across central and northern parts of the state. These beetles prefer sandy soils and natural areas like longleaf pine uplands or scrub habitats, quietly tunneling through dung from wildlife or livestock.
And then there’s the Florida deepdigger scarab (Peltotrupes profundus), an endemic species found only in Florida. This dark, robust beetle creates conspicuous sand mounds in scrubby or pine-covered landscapes. Below those mounds? Tunnels that can run several feet deep. These beetles aren’t exclusive dung feeders – they mix organic matter into the soil, creating long-lasting soil channels that help roots breathe and water move more freely.

Finally, we have one native species that actually does roll its dung: the aptly named common tumblebug (Canthon pilularius). This smaller black beetle sculpts dung into neat balls and rolls them away to bury. They’re usually seen in open areas and pastures during the warmer seasons. If you spot one, enjoy the show – they’re fast, efficient, and usually gone in minutes.
Non-Native Dung Beetles in Florida
Several non-native dung beetle species have also become established in Florida, introduced in the 1970s to help manage cattle manure in pastures. These include species like the gazelle dung beetle (Digitonthophagus gazella), bull-headed dung beetle (Onthophagus taurus), and the sandy dung beetle (Euoniticellus intermedius). All three are tunnelers that quickly bury fresh dung, reducing fly populations and improving soil fertility. They’re now widespread in pastures across North Florida, especially in the summer and fall. Another common non-native is the European dung beetle (Aphodius fimetarius), a small red-and-black species that acts as a dweller, living and breeding directly within the dung pile itself.

While none of these introduced beetles are currently considered invasive, some researchers have raised concerns about how they might compete with native species for dung – especially in heavily grazed pastures. That said, most tend to stick close to livestock areas and haven’t been shown to disrupt natural ecosystems in a meaningful way.
Soil Helpers, Garden Allies
For gardeners and farmers alike, dung beetles are some of our most efficient natural tillers. Their tunneling mixes organic matter deeper into the soil profile, improving structure and water infiltration. That means fewer compaction issues and better moisture retention during our dry spells. In pastures, studies have shown that they can improve grass growth and reduce runoff – pretty remarkable for something that lives in poop.
If you’re already focused on fostering a sustainable landscape, be sure to give dung beetles a spot on your list of wildlife to appreciate and protect. In a world full of tidy lawns and picture-perfect beds, dung beetles remind us that beauty isn’t always what you see on the surface. Sometimes, the real work is happening just below it.

The gloriosa lilies have been in full glory, so to speak, in our garden at the Extension office the last few weeks. While photographing them, I noticed a tiny visitor hidden in plain sight among the flower’s frilly petals and stamen. A bright green juvenile praying mantis, no more than an inch long and the same shade of green as the plant, stood still directly in front of me.

Praying mantids are often recognizable and well-known due to their interesting body shape and posture. They have other wild features, too, like gigantic folding “raptorial” (grasping/predatory) front legs and the ability to swivel their big-eyed, alien heads 180°. The large European mantid’s Latin name, Mantis religiosa, comes from the insect’s posture when hunting. It sits or stands with its forelegs folded up as if in prayer, before deploying them rapidly for a meal. All mantid species are ambush predators, capturing prey by sitting in wait, camouflaged in color and shape. They’ve even been observed swaying gently to appear like leaves in the breeze. But when they spring to attack, they are deadly accurate.

The insects are known for their infamous (but rare in the wild) post-mating male beheading. Mantids are not alone in that cannibalistic behavior—many insects and spiders exhibit this conduct to boost the energy of females as they produce the next generation. Most mantid species are tropical, but of the 2400 known worldwide, only about 20 live in the United States (11 in Florida).
Mantids are considered natural pest control in a garden, although they are generalists and will prey on both beneficial and pest insects. With those spiky front legs raised in the air, they drop down and grasp prey ranging in size from aphids to—rarely—hummingbirds. Their effective predatory behavior doesn’t make them immune from becoming prey themselves, however. Mantids are a food source for many species, including bats, birds, spiders, and fish.
When most people think of insects, they think of the bad ones, but not all insects are bad! Insects are labeled as bad or ‘pests’ when they start causing harm to people or the things we care about such as plants, animals, and buildings but most insects are GOOD! In fact, of the millions of insect species found throughout the world, less than 2% are actually considered pests. There are several different ways insects can be beneficial in your garden or landscape:
They prey on pest insects. Many species of insects eat pest insects! For example, lady beetles (ladybugs) and lacewings eat pest insects like aphids, mealybugs and whiteflies. They can help keep insect populations in balance. It’s important to recognize some of the beneficial insect species (and their different life cycle stages) that you might find in your garden. The UF/IFAS Extension bookstore has a great identification guide: Helpful, Harmful, Harmless?
They parasitize pest insects. Some species of good insects live in or on pest insects. For example, parasitoid wasps lay their eggs into pest insects and when the wasp eggs hatch, they feed on the pest species. Here’s a really great video to show the process: Parasitic Wasps – National Geographic
They pollinate. Many of the good insects like native bees, honeybees, butterflies and moths help us pollinate our gardens. They transfer pollen grains from flower to flower that help plants bear fruit.
They decompose. Insects also help aerate our soils by breaking down dead material and recycling nutrients. Dung beetles are a great example! They bury and consume dung which improves soil quality.
One of the best things you can do for your garden is learn to differentiate pest insect species from beneficial ones! Just because you see an insect on your plant, doesn’t necessarily mean it is causing harm. If you see an insect, are you seeing injury to the plant? If so, what type of injury (defoliation, yellowing, leaf curling)? If you aren’t seeing injury, then you may not have anything to worry about. If you find something you’re unsure of, you can always reach out to your local UF/IFAS Extension Agent!

Attracting and encouraging beneficial insects can really help your garden and landscape thrive. The best way to attract beneficial insects to your garden or landscape is to have lots of plant diversity. A mix of trees, shrubs, annual and perennial flowers in the landscape is best. Trees and shrubs will provide shelter for insects to overwinter, and flowers provide pollen and nectar.
Flowers in the carrot family (Apiaceae) such as caraway, coriander, cilantro, dill and fennel are attractive for parasitic wasps. Flowers in the Aster family (Asteraceae) such as blanketflower, coneflower, coreopsis, cosmos and goldenrod are attractive for larger predators like lady beetles and soldier beetles. These can be incorporated into the garden or flower beds.
