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).
While we think of most flies as pests, garden flies, such as Allograpta obliqua species found in Florida, are excellent pollinators and insect predators. Photo by Jessica Louque, Smithers Viscient, Bugwood.org.
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.

Bees are the primary pollinators of plants, essential in natural and crop environments for guaranteeing global food security to the human population. Florida is home of more than 300 species of native wild bees, which rely on pollen and nectar from flowers to survive. However, a global pollinator decline reported for honeybees and wild species (including insects, birds, and bats), is decreasing the worldwide provision of pollination services. Food limitation (pollen and nectar), resulting from decreasing flower diversity and quantity, is one of the multiple causes of pollinator decline. Pollinator-friendly plants are receiving attention from people of various disciplines such as the scientific community, stakeholders, Master Gardeners, and citizen science groups willing to participate in pollinator conservation efforts.
Domestic gardens
Domestic gardens comprise a substantial proportion of land in the urban landscape and are often the most significant component of green space; they play essential roles in conserving plant genetic resources, insects, and other wildlife, and have social and economic value. Gardens behave as islands of usable habitat surrounded by urbanization, and they present varying benefits for pollinators. There is generally a positive relationship between high pollinator abundance, flower diversity, and bloom evenness. Gardens for pollinators propose to solve the pollinator crisis by enlarging greenspaces in urban areas by planting more flowers in urbanized environment and by improving the diversity of floral resources for pollinators.
Pollinator friendly plants
There are different categories of floral traits: qualities that attract pollinators such as floral size and color, and physical characteristics that reward the pollinator (nectar and pollen quantity and quality). Flowers with higher quality and quantity rewards are more attractive to pollinators. Nectar provides the main sugar source for insect pollinators; its energetic value is determined by its sugar concentration. The volume of nectar produced by flowers will directly affected visitation by honeybees and bumblebees, butterflies, and birds. Pollen on the other side, consists of the main source of protein for most pollinators.
RECOMMENDATIONS
1. Provide a Mix of floral shapes and sizes.
There is usually a positive correlation between flower size and nectar volume: long tube flowers usually provide more nectar, whereas open or flat flowers provide more pollen. In addition, flower shapes are also associated with different pollinator types (Fig. 1). Long-tongued insects (Butterflies, and some bees) visit deep corolla tube flowers, while short-tongued pollinators (wasps, flies and some bees) remain on short tube or open corolla flowers.

Silva); Carpenterbee on Salvia Indigo spires (Salvia longispicata x farinaceae) (Credits: Kelly Thomas); Sweat bee on Gaillardia pulchella) (Credits: Joanna J. Silva).
2. Provide a mix of flower colors
Color patterns influence the flower’s attractiveness and increase the efficiency of pollination by helping insects orient on the flower and guide them to the reward (Fig. 2). Bees prefer white, yellow, or blue-purple flowers. Orange, pink, and red flowers attract other pollinators such as butterflies.

It is probably not native to the rest of the eastern USA as previously thought (ISB: Atlas of Florida Plants (usf.edu), Gaillardia – University of Florida, Institute of Food and Agricultural Sciences (ufl.edu)).
3. Include a pollinator hotel
Add a bee nest box for the native bees that build their nests above ground. Solitary bees and wasps will take up residence in a pollinator hotel after you place it outside.
4. Provide flowers throughout the year.
Pollen and nectar collection varies seasonally for honeybees, while many other solitary bee species collect pollen continuously during adult foraging to feed their larvae. Design the garden to have three or more different plants blooming at any given time during the growing season, which is March through November in northern areas of the state (Fig. 3).

5. Include native plants.
A “Florida native plant” refers to a species occurring within the state boundaries prior to European contact, according to the best available scientific and historical documentation. Florida is home to over 4,867 species of plants; 3,314 species are considered native of which 230 species are endemic.
6. Chose the right plant for each location.
Success depends on using the right plant in the right place, especially by considering plant’s cold hardiness (Fig. 4). Plant selection for landscapers, nurseries, and gardens requires individual site criteria and an evaluation of individual plant performance under different environmental circumstances, such as water, soil, and temperature.

The Annual Tupelo Honey Festival will be held Saturday, May 21st from 9 am – 4 pm central time at Lake Alice Park in Wewahitchka. This is an exciting event, with your chance to take part in a local treat. Area honey producers will be on hand, selling their honey in a variety of sizes. There will also be food, art & crafts, and live music.
For decades, tupelo honey has been synonymous with Gulf County. The nectar from the tupelo gum tree (Nyssa ogeche), produces some of the finest honey in the world. The common name “tupelo” is derived from language of the Muscogee Nation, also known as the Creek Indian Nation. The meaning of the word is “swamp tree”, as this tree flourishes in areas of wet soils and seasonal flooding. Gulf County is home to one of the largest tupelo forests on earth.

The tupelo bloom season lasts from approximately mid-April to the end of May. This is an anxious time for beekeepers. Tupelo blooms are very temperamental and delicate in nature. For this short period, beekeepers hope for little wind or rain and no cold temperatures, as any of these factors can make or break tupelo honey production. Regardless of seasonal impacts, the demand for Gulf County’s tupelo honey never subsides.
Please visit http://www.tupelohoneyfestival.com/ for more information on the festival. For more information on beekeeping, contact Gulf County Extension at 639-3200.
UF/IFAS Extension is an Equal Opportunity Institution.
