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.

As spring approaches, are we thinking about pollinators? 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.
Are we creating an ecosystem aesthetically pleasing while attracting pollinators?

The planting of native wildflower in Florida can benefit agricultural producers likewise, native pollinators and other beneficials 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 wildflower when restoring habitats for our pollinators. Mix varieties will flower all year round and make available continuous supply of nectar and pollen. If possible, use wildflower seeds that are produced in the state that you want to carry out pollinators’ 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 pesticide 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.

Are you one of those that hear the word “pollen” and sneeze? For many, allergies are the only association with plant pollen. But pollination – the transfer of male pollen grains into the female flower organs to create fertile seeds – is an essential part of a healthy ecosystem. Pollinators play a significant role in the production of over 150 food crops. Corn and rice are wind pollinated. Just about everything else, including chocolate, depends on an insect, bird or mammal. Successful pollination of a single flower often requires visits from multiple pollinators. But, there are also plants that need a specific species in order to complete the task. They are so interdependent that if one disappears, so will the other.
Unfortunately, reports from the National Research Council say that the long-term population trends for some North American pollinators are “demonstrably downward”.
In 2007, the U.S. Senate unanimously approved and designated “National Pollinator Week” to help raise awareness. National Pollinator Week (June 21-27, 2021) is a time to celebrate pollinators and spread the word about what you can do to protect them. Habitat loss for pollinators due to human activity poses an immediate and frequently irreversible threat. Other factors responsible for population decreases include: invasive plant species, broad-spectrum pesticide use, disease, and weather.
So what can you do?
Install “houses” for birds, bats, and bees.
Avoid toxic, synthetic pesticides and only apply bio-rational products when pollinators aren’t active.
Provide and maintain small shallow containers of water for wildlife.
Create a pollinator-friendly garden.
Plant native plants that provide nectar for pollinating insects.
There’s a new app for the last two.
The Bee Smart® Pollinator Gardener is your comprehensive guide to selecting plants for pollinators based on the geographical and ecological attributes of your location (your ecoregion) just by entering your zip code. http://pollinator.beefriendlyfarmer.org/beesmartapp.htm
Filter your plants by what pollinators you want to attract, light and soil requirements, bloom color, and plant type. This is an excellent plant reference to attract bees, butterflies, hummingbirds, beetles, bats, and other pollinators to the garden, farm, school and every landscape.
The University of Florida also provides a website to learn the bee species and garden design. Go to: https://ffl.ifas.ufl.edu/bees/Bee
Not only can you find out which plants attract pollinators, you will be given the correct growing conditions so you can choose ‘the right plant for the right place’.
Remember, one out of every three mouthfuls of food we eat is made possible by pollinators.
