The Q&A on Native Pollinators and their Favorite Flowers offered valuable information on many types of flowers that feed our many species of pollinators in Northwest FL. Below are the reference materials related to specific questions that were asked along with notes from the panel discussions.
- Stephen Greer was asked which garden perennials are best for pollinators, he mentioned that Blanketflower, Cardinal Flower, Black Eyed Susan were his top three.
- Julie McConnell was asked, what are some shrubs to benefit birds and pollinators? She stated that insects forage off lawn grasses, but good shrubs are Wax Myrtle, Saw Palmetto, American Beautyberry, Vibernum and Holly Species. Sandy Soil Pollinators: Firebush, Holly, Saw Palmetto, all drought tolerant and good for pollinators.
- Julie McConnell was asked about Fall Pollinator Plants, replying Swamp Sunflower as her favorite.
- What about Winter Pollinator Plants?
- Winter: Mahonia, Fatsia, both good plants for pollinators in shady areas, also Beth added that winter vegetables help pollinators in the winter, such as carrot, wild radish, provide forage for bees, bumblebees and plasterer bees, carpenter bees. Matt Lollar said daikon radish is another good pollinator plant for fall and winter.
- Question from Facebook: Are Loquat trees good for pollinators. How large do they get and when do they bloom? Do they need shade or full sun?
- Are Spicebushes good Pollinator Plants?
- Herbs: Perfect Plants for Pollinators
- What is best for Butterfly Gardening in Florida?
- What are some Favorite Pollinator Plants?
- Better access to native plants: Florida Native Plant Society
- There are Native Plant Nurseries in Bay and Leon County, you can find them on google.
- Some Master Gardner Volunteer programs sell native plants at their sales!
- Stephen: What methods have been successful to approach HOA’s to approve of Native plants in homeowner’s properties?
- Build consensus about native plants before the meeting.
- Covenants or Bylaws. Covenants are less enforceable, Bylaws have enforcement ability.
- Beth: Do we need to supply water for pollinators? YES!
- Is Carolina Jessamine good for bees?
- Growing Sunflowers from seed:
- How Much Bidens alba is enough?

As you garden this fall, check out the North Florida Vegetable Gardening Guide, compiled by UF/IFAS Leon County Extension.
Getting into vegetable gardening, but don’t know where to start?
Even experienced gardeners know there’s always more to learn. To help both beginners and advanced gardeners find answers to their questions, the UF/IFAS Leon County Extension Office put together the North Florida Vegetable Gardening Guide. It incorporates multiple resources, including articles, planting calendars, photos, and UF/IFAS EDIS publications.
The North Florida Vegetable Gardening Guide covers the many aspects of vegetable gardening, including how to get started, site selection, insects and biodiversity in the garden, soil testing, composting, cover crops in the garden, irrigation, and more.
You can click here to view the digital version of the guidebook. We also have physical copies of the guide available at the UF/IFAS Leon County Extension Office (615 Paul Russell Rd., Tallahassee, FL 32301).
Happy fall gardening!

Over my years of leading people on interpretive trail hikes, I have learned it is particularly important to know the names of the plants that are in bloom. These flowers are eye-catching, and inevitably someone will ask what they are. In fact, one of my favorite wildflower identification books is categorized not by taxonomy, but by bloom color—with a rainbow of tabs down the edge of the book for easy identification.

In our coastal dunes right now, several plants are showing off vibrant yellow blooms. Seaside goldenrod, coreopsis, and other asters are common. Rarer, and the subject of today’s post, is the Coastal Plain Honeycombhead (Balduina angustifolia). It has bright yellow flowers, but often gets more notice due to its unusual appearance when not in bloom. The basal leaves are bright green and similar in shape and arrangement to a pine cone or bottlebrush (albeit a tiny one), sticking straight up in the sand. The plants are typically found on the more protected back side of primary dunes or further into secondary dunes, a little more inland from the Gulf.

The plant plays a special role in beach ecology, as a host plant for Gulf fritillary butterflies and the Gulf Coast solitary bee (Hesperapis oraria). The bee is a ground-dwelling pollinator insect that forages only in the barrier islands of Mississippi, Alabama, and Florida. The species is currently the subject of a University of Florida study, as the endemic bee’s sole source of nectar and pollen is the honeycombhead flower. As of publication date, no bee nests have been discovered. Researchers are interested in learning more about the insect’s life cycle and nesting behaviors to better understand and protect its use of local habitats. Based on closely related species, it is believed the Gulf Coast solitary bee builds a multi-chambered nest under the soft sands of the dunes.

While the honeycombhead plant is found in peninsular Florida and coastal Georgia, the bee has been identified only in a 100 km² area between Horn Island, MS, and St. Andrews Bay, FL. Luckily for the bee, large swaths of this land are preserved as part of Gulf Islands National Seashore and several state parks. Nonetheless, these coastal dune habitats are threatened by hurricanes, sea level rise, and development (outside the park boundaries). Due to its rarity and limited habitat, a petition has been submitted to the Fish and Wildlife Service for protection under the Endangered Species Act.
While most people are familiar with the European honey bee, the domesticated insect that pollinates our crops and provides us with honey, there are plenty of other species of bees and their relatives out there. Most of them are harmless, spending their time quietly pollinating plants, including our crops. Their presence in the landscape, however, may cause some alarm, as it can be difficult for the untrained eye to distinguish between aggressive species and those that are innocuous.

Homeowners may occasionally note small mounds of soil in sandy areas of their lawns. Sometimes sporting a small hole in the center, these are the nesting sites of solitary, ground-nesting bees or hornets. Miner bees or digger bees build underground chambers, usually in well-drained, otherwise bare areas of sandy soil. Multiple bees may choose to dig their nests in the same location, though each bee makes its own tunnel and they do not live communally. Each bee lays her eggs in the nest she has excavated. She gathers pollen to feed the young when they hatch, stocks the larder, and leaves. When the young emerge from the nest, they fly away and do not remain; they will dig their own nests when they are ready to reproduce. While there is no need to control these insects (they serve as fantastic pollinators), the mounds of soil they make may be aesthetically displeasing to some people. Keeping a healthy lawn with no bare patches can deter miner bees from nesting in an area. Irrigation sprinklers can also help to keep the ground moist; these bees prefer dry soil, so it may keep them away. Care must be taken not to over-water a lawn, however!

Another species of note is the cicada killer hornet. Also known as the giant ground hornet, these insects grow to a size of about an inch and a half in length. Instead of pollen, they capture cicadas to feed their young. Like the miner bee, though, they are not harmful. Females do possess a stinger which they use to hunt their prey. Males may try to warn people or animals away from their burrows by acting aggressive, but they have no stingers. Some may see the large size of the cicada killer and wonder if the so-called “murder hornet” has made its way from Washington state to Florida, but as of this writing it has not. Unless you are a cicada, you have nothing to fear.
One ground-dwelling hornet that does warrant some concern is the yellowjacket. These are communal hornets, living in hives that are often build underground. Yellowjackets are known for their bad attitudes, attacking anyone who disturbs the entrance to their nest. They can be beneficial, being predators of many other insects including plant pests. A colony located too close to human dwellings or areas of activity is most often a nuisance, however. Any attempts to control yellowjacket nests should be done at night when they are less active. Protective clothing is recommended even then. Large or difficult to reach nests may require the attention of a certified pest control company.

Fall is the absolute best season for wildflower watching in the Panhandle! When mid-September rolls around and the long days of summer finally shorten, giving way to drier air and cooler nights, northwest Florida experiences a wildflower color explosion. From the brilliant yellow of Swamp Sunflower and Goldenrod, to the soothing blue of Mistflower, and the white-on-gold of Spanish Needles, there is no shortage of sights to see from now until frost. But, in my opinion, the star of the fall show is the currently flowering False Foxglove (Agalinus spp.).
Named for the appearance of their brilliant pink flowers, which bear a resemblance to the northern favorite Foxglove (Digitalis spp.), “False Foxglove” is actually the common name of several closely related species of parasitic plants in the genus Agalinus that are difficult to distinguish by all but the keenest of botanists. Regardless of which species you may see, False Foxglove is an unusual and important Florida native plant. Emerging from seed each spring in the Panhandle, plants grow quickly through the summer to a mature height of 3-5’. During this time, False Foxglove is about as inconspicuous a plant as grows. Consisting of a wispy thin woody stem with very small, narrow leaves, plants remain hidden in the flatwoods and sand hill landscapes that they inhabit. However, when those aforementioned shorter September days arrive, False Foxglove explodes into flower sporting sprays of dozens of light purple to pink tubular-shaped flowers that remain until frost ends the season.

In addition to being unmatched in flower, False Foxglove also plays several important ecological roles in Florida’s natural areas. First, False Foxglove’s relatively large, tubular-shaped flowers are the preferred nectar sources for the larger-sized native solitary and bumble bees present in the Panhandle, though all manner of generalist bees and butterflies will also visit for a quick sip. Second, False Foxglove is the primary host plant for the unique Common Buckeye butterfly. One of the most easily recognizable butterflies due to the large “eye” spots on their wings, Common Buckeye larvae (caterpillars), feed on False Foxglove foliage during the summer before emerging as adults and adding to the fall spectacle. Finally, False Foxglove is an important indicator of a healthy native ecosystem. As a parasitic plant, False Foxglove obtains nutrients and energy by photosynthesis AND by using specialized roots to tap into the roots of nearby suitable hosts (native grasses and other plants). As both False Foxglove and its parasitic host plants prefer to grow in the sunny, fire-exposed pine flatwoods and sand ridges that characterized pre-settlement Florida, you can be fairly confident that if you see a natural area with an abundance of False Foxglove in flower, that spot is in good ecological shape!
The Florida Panhandle is nearly unmatched in its fall wildflower diversity and False Foxglove plays a critical part in the show. From its stunning flowers to its important ecological roles, one would be hard-pressed to find a more unique native wildflower! For more information about False Foxglove and other Florida native wildflowers, contact your local UF/IFAS County Extension office.
In a garden with a variety of flowers, pollinators will be abundant. Sometimes we don’t always recognize the specific pollinator when we see it, but there are some native pollinators that leave other signs of their activity. One of our medium-sized native bees will leave a distinctive calling card of recent activity in our landscape.

If you see some of the leaves of trees and shrubs with distinct circular notches on the edges of the leaves, you can be sure the Leafcutter bee is present. The females collect the leaf pieces to make a small, cigar-shaped nest that may be found in natural cavities, such as rooting wood, soil, or in plant stems. Each nest will have several sections in which the female places a ball of pollen and an egg. The emerging larvae then have a plentiful food source in order to develop into an adult bee.
When identifying a leafcutter bee in your landscape, look for a more robust bee with dark and light stripes on the abdomen. These bees also have a hairy underside to their abdomen where they carry the pollen. When loaded with pollen their underside will look yellow.
Leafcutter bees are solitary bees that are not considered aggressive. A sting would only be likely if the bee is handled. Your landscape will have many plants that a leafcutter may use for nesting material. The pollinating benefits of these bees far outweigh any cosmetic injury to the plant leaf margins.
