If you are looking for a low maintenance plant that has attractive foliage and flowers and attracts wildlife, consider planting fennel. Fennel was planted in the pollinator garden at the Extension office in Bay County as a butterfly host plant for swallowtail butterflies in 2014 and has been a showstopper ever since. Fennel is a short-lived evergreen perennial that will reseed in the garden, but it is easy to remove plants if you get too many. It performs well in full sun to light shade and is quite drought tolerant once established.
The fernlike foliage has a delicate texture that contrasts with most landscape plants. Large umbels of tiny yellow flowers reach for the sky each spring and attract lots of pollinators and butterflies to the garden. Fennel is a culinary herb and leaves, flowers, and seeds can be used to season dishes with the mildly licorice flavor.
Fennel can reach 6 feet tall when in full bloom. J_McConnell UF/IFASFennel is a host plant of Eastern black swallowtail caterpillar. J_McConnell UF/IFASHoney bee visiting fennel flowers.

Like finding buried treasure on a desert island, walking up on a mound of sandhill milkweed (Asclepias humistrata) may elicit cries of excitement from someone who understands what they’re seeing. And not unlike searching for pirate booty, there’s a bit of danger involved, too—milkweed is highly toxic.

Last month in the dunes of Perdido Key, our Master Naturalist class found robust clusters of eye-catching, pink-tinged leaves, blooms, and buds of sandhill milkweed. Also known as pinewoods milkweed, this variety thrives in dry, sandy soils. It is native to the southeast, found typically in the wilds of Alabama, Mississippi, Louisiana, Georgia, Florida, South Carolina, and North Carolina. Its genus name, “Asclepias” refers to the Greek god of healing—indigenous people have used the plant for medicinal purposes (dysentery treatment and wart removal, in particular) for centuries. The species name humistrata means “spreading,” which describes the growth habit of the plant. Milkweed is highly toxic, so we do not recommend trying any medicinal uses at home! The “milk” part of the common name refers to its sap, which is a thick, sticky, white substance containing that toxic chemical.

As the only food source for the monarch caterpillar, healthy milkweed plants are crucial for maintaining populations of the famous monarch butterfly. The plant itself is rather complex and beautiful. Its five-petaled blooms grow in tight clusters, on stalks sticking several inches off the ground. The leaves are broad and a deep forest green, edged in the pale maroon/pink of the stems and flowers. The seedpods of milkweed are quite large (3-6” long), resembling pea pods and full of seeds. Each seed has a wispy white fiber attached, which helps it disperse in the wind like a dandelion. The fibers have been used for years as stuffing for pillows and mattresses, and were used for life jackets during World War 2.

The first cluster of milkweed we found was host to multiple monarch caterpillars, recognizable by their greenish-yellow, white, and black stripes. By the time you see caterpillars, the milkweed is already working its magic, transferring its toxins to the insects but causing them no harm. Monarchs have evolved the capability to digest and metabolize this poison, which would induce heart attacks in nearly any vertebrate animal. Adult monarchs use several nectar sources, including milkweed flowers, and females lay their eggs on the plant so that their young can begin eating once hatched.
In the animal kingdom, red and orange are signs of danger. The bright orange coloration of an adult monarch butterfly serves as a warning to would-be predators to exhibit caution, as the toxins from their food sources stay within the butterfly’s body. The copycat viceroy, soldier, queen, and Gulf fritillary butterflies benefit from this trait by using mimicry in their own orange coloration to ward off predators.
How often do we stop to think of the importance of pollinators to food security?
Pollination is often described as the transfer of pollen grains from the anther to the stigma of a flowering plant. These transfers are made possible due to pollinator visits in exchange of pollen and nectar from the plants.
Who are our pollinators?
Main Global Pollinators
Social Solitary
Honeybees Alfalfa leafcutter bee
Bumble bees Mason bees
Stingless bees Other leafcutter bees
How can we care for pollinators?
We can care for our pollinators by growing plants that have abundant and accessible pollen and nectar.
Choose plants with flat flowers or short to medium-length flowers tubes (corollas), and limit plants with long flower tubes such as honey suckle.
Avoid plant varieties that do not provide floral rewards (pollen), which is the essential food source for bees. (e.g., some sunflower, and lilies).

Many native wild bees have relatively short proboscises, or tongues, and may not be able to access nectar from flowers with long tubes; however, flowers with long floral tubes can attract other pollinators with long tongues or beaks such as butterflies, moths, and hummingbirds.

The planting of native wildflowers in Florida can benefit agricultural producers likewise, native pollinators and other beneficial such as parasitoids and predators.
Some of the main benefits of growing native wildflower are:
Increasing wild bee presence in the surroundings
Providing nesting and foraging sites for pollinators, butterflies, bees etc.
Increasing natural enemies of pest insects.
It is important to select mix varieties of native wildflowers when restoring habitats for our pollinators. Mix varieties will flower all year round and make available a continuous supply of nectar and pollen. If possible, use wildflower seeds that are produced in the state that you want to carry out pollinator restoration. It is highly likely that one will experience better growth from locally produced seeds because they will adapt better to regional growing conditions and the climate. For optimum flowering and high production of floral rewards such as pollen and nectar, place wildflowers in areas free of pesticides and soil disturbance.
Most bee species are solitary, and 70% of these solitary bees’ nest in the ground. A wildflower area of refuge can fulfill the shelter resource needs of these bees since that area will not undergo regular tilling, thus minimizing nest disturbance.

To celebrate “No Mow March”, this month’s Gardening in the Panhandle LIVE was all about pollinators. “No Mow March” was inspired by “No Mow May” events that were originally organized in Great Britain then adapted by some of our more northern states. Lawns in the panhandle definitely need to be mowed in May, so we set our sights on March.
Most warm season turfgrass species don’t grow much (or at all) in March, but some people may feel the need to mow their lawns. If you feel the need to mow, we recommend you leave the borders of your lawn or a small area un-mowed. This will encourage flowering plants to bloom and bring more pollinators to your yard.
Butterflies are loved by many for their beauty, but they also pollinate a lot of our favorite plants. To encourage butterflies to visit your garden, try planting some things they like to eat. The publication “Butterfly Gardening in Florida” provides lots of information about bringing butterflies to your yard. Be sure to check out the tables in the article for information on seasons and life cycles. If butterflies aren’t your thing, then search for plants by pollinator species in this webpage on Nectar Plants. Some plants have Extrafoliar Nectaries to attract a diversity of insects.
If you’re interested in anything about any insect, then you’ll enjoy the Featured Creatures website. You can search by species name or by what they like to eat.
Not all bees live in hives. Some bees, like mason bees, prefer to live in above ground “houses” or “hotels”. You can build your own pollinator hotel if you follow the simple steps found in the article “Build Your Own Pollinator Hotel”. And here’s even more information on “gardening for bees”.
Some of us live in the woods and need suggestions on shade loving plants. The article “Landscaping in the Shade” provides some good information on what plants can handle shady spots. A number of different ornamental gingers like the shade.
Turfgrass isn’t the only groundcover on the market. There are lots of alternatives like frogfruit and perennial peanut that attract pollinators.
If you’re interested in being a part of “No Mow March”, the first step is to sign the pledge at go.ufl.edu/NoMowMarch. Also, be sure to record your “No Mow March” observations at iNaturalist.
Past episodes of Gardening in the Panhandle LIVE can be found on our YouTube playlist.
Do you enjoy a tasty bowl of fruit in the morning? Or maybe a hot steaming cup of coffee? If the answer is yes, then raise (or tip) your hat to our pollinators. About 75% of food crops depend on pollination to some extent, but pollinators provide the bulk of the pollination for over 80% of the world’s flowering plants. A pollinator can be birds, bats, or even small mammals but, insects such as ants, bees, beetles, wasps, butterflies, and moths do the bulk of the pollination that affects our daily lives.
Plants normally benefits from attracting a particular type of pollinator to their flowers, ensuring transfer and hopefully resulting in reproduction. The pollinator benefits from its adaptation of a particular flower with different traits to access nectar and pollen. These floral traits include odor, color, size, flower shape, reward type, amount, nectar composition, and timing of flowering. This plant pollinator interaction is known as pollination syndrome.
Did you know –
That tubular red flowers with a lot of nectar often attract birds.
Also, foul smelling flowers attract carrion flies or beetles.
Butterflies and moths can help spread pollen; however, they don’t have any specialized structures for collecting pollen.
Beetles pollinate more than 80% of all flowers – clusters of flowers are ideal because beetles are clumsy fliers.
While bees are drawn to plants on the blue, white, purple, and yellow color spectrum. Bees possessing hairs and other specialized anatomical structures that can readily collect and transfer pollen, making them an important plant pollinator. However, the honey bee, (Apis spp.) is the world’s top pollinator and is responsible for one-third of what we eat, yet they are just a small representative of all the bee species.

Did you Know-
Everyone can contribute to pollinators by creating a home garden. Pollinators will make use of food and habitat anywhere it is found – roadsides, open fields, pastures, backyard flower gardens etc. One can be pollinator friendly by doing any of the activities below:
Plant an assortment of plants – varying in color, size and type to support a greater number and diversity of pollinators.
Plant nativeplants – as they are considered the best choice due to their abundance of nectar and pollen, among other benefits.
Use little or no pesticides – instead maintain a sustainable garden with the suitable plant species that will support natural beneficial insects—reducing the need for pest control.
Educate– others about the importance of pollinators.
Seasonal planting – Choose pollinator plants that bloom in spring, summer, and fall. Timing is crucial – plant flowers in clumps that bloom in early spring (emerging winter hibernation) and late summer (preparing for hibernation) so bees have adequate food supply.
Provide habitat or installbat boxes. Bats play a vital role in pollinating flowers and dispersing seeds.
