It’s a bit early still for blueberries in north Florida, but they are definitely on the horizon. We have a handful of bushes at home and the office, and I’ve noticed the white blooms are gone and berries are forming as we speak. Many of us, myself included, look forward to the late-spring harvest of blueberries, taking our children out to u-pick operations and hunting down family recipes for blueberry-filled desserts.
Often, when people think of fruit growing in the wild, their minds naturally go to tropical rainforests, with visions of bananas, mangoes, and drooping fruit-laden trees. But blueberries are a home-grown local Panhandle fruit. A walk through any self-respecting northwest Florida wooded area is bound to have blueberry bushes growing wild. Vaccinium species thrive in more acidic soil, (between 4-6 on pH scale), which we have in abundance here. In northwest Florida, we have lots of pines and oaks dropping needles and leaves, seasoning our soil to a 6 or lower on the pH scale. Central and south Florida soils are alkaline due to all of the natural limestone, so while blueberries are grown on farms down south, they’re rarer in the wild.
Blueberries are pollinated by bees of many stripes, but most people are unaware of the specialized bee that literally lives for this season. During the last few weeks, this species has been furiously pollinating blueberry bushes during its short, single-purpose lifetime.

Southeastern blueberry bees (Habropoda labriosa) are active only in mid-March to April when blueberry plants are in flower. They are smaller than bumblebees, and yellow patches on their heads can differentiate males. Blueberry pollen is heavy and sticky, so it is not blown by the wind, and the flower anatomy is such that pollen from the male anther will not just fall onto the female stigma. Blueberry bees must instead attach themselves to the flower and rapidly vibrate their flight muscles, shaking the pollen out. Moving to the next flower, the bee’s vibrations will drop pollen from the first flower onto the next one. This phenomenon is called “sonicating” or ‘buzz pollination” and is the most effective method of creating a prolific blueberry crop.

This native bee lives most of its life underground, emerging in the spring when blueberries are in bloom and living long enough to pollinate the plants. Blueberry bees do not form hives, but create solitary nests in open, sunny, high ground. Females will dig a tunnel with a brood chamber large enough for one larva, filling it with nectar and pollen. After laying an egg, the female seals the chamber and the next generation is ready. The species produces only one generation of adults per year.
By the time we are picking fresh blueberries in May and June, you probably won’t see any blueberry bees around. However, we should all consider these insects’ short-lived but vitally important role in Florida’s $70 million/year blueberry industry!
An activity during our No Mow March campaign was for participants to document flowers and pollinators from their landscapes. This activity was available through an INaturalist group specific to No Mow March. Although we only had 13 participants, they made 85 observations representing 50 species of plants and insects.
The photo that was selected as the favorite is the Clasping Venus’s Looking Glass, Triodanis perfoliate, by Martha W. This was around the Tallahassee, FL area. Martha received an electric edger, battery, and charger.
We hope to have more participants in our photo collection next year as we observe the plants and pollinators visiting our landscapes when we don’t mow.
No Mow March was an awesome success this year! Together, by leaving some unmown areas of our lawns and landscapes, we helped create acres of additional valuable pollinator habitat in a critical time of the year. However, we can’t forget that there are still nine months remaining in which we can provide low-maintenance food and shelter for pollinators and other wildlife in our landscapes this year! The following are three of my favorite ultra-low maintenance pollinator friendly shrubs for Panhandle landscapes for summer and fall.
Chaste Tree (Vitex agnus-castus)
Chaste tree or vitex, an outstanding Florida-Friendly Landscape shrub/small tree, provides many aesthetic and wildlife landscape benefits throughout the growing season. Vitex features attractive grayish-green foliage and grows into a nice, rounded shape (10-15’ tall). However, the primary draw is its summer/fall flower show. Sporting striking masses of purplish-blue flowers for months on end until frost, Vitex is a pollinator magnet. Bees, butterflies, hummingbirds, and all manner of other pollinators visit vitex when in bloom and birds frequent the shrub in the fall to feed on its seeds. Simply select a site with full sun and well-drained soil and Vitex will reward gardeners and pollinators for years to come.
Firebush (Hamelia patens)
Firebush is a showstopper for both passers-by and pollinators. This sorta native shrub (Florida native but does not occur naturally in the Panhandle), is a prolific producer of tubular, bright-red flowers from late spring-through frost. These flowers are a preferred nectar source for many species of butterflies, Zebra longwing and Gulf Fritillary included, and a favorite of hummingbirds. Like vitex, birds also enjoy feeding on the berries that follow firebush flowers. In the Panhandle, firebush tops out at around 6’ tall and about as wide and is often killed back to the ground by frost, regrowing rapidly each spring. Firebush has no real insect or disease issues in landscapes and prefers the same sites as Vitex and will appreciate as much sun as you can give it and well-drained soil.

American Beautyberry (Callicarpa americana)
American beautyberry, or just Beautyberry as it is commonly referred to, is a lovely little deciduous shrub native to all parts of Florida and provides benefits to all manner of landscape wildlife. Though primarily known for its bird-attracting, vibrant purple berry clusters that appear late summer through fall, Beautyberry is a host plant for several butterfly/moth species and its dainty, pink flowers are an early summer favorite of many bees! Beautyberry grows 5-7’ in height and is extremely adaptable in landscapes as well, thriving in sun or light shade and many different soil conditions.

It’s important to remember that providing pollinator/bird food and habitat in lawns and landscapes is not a one month event, but a year round commitment. Reducing mowing frequency, reducing pesticide use, planting native trees, including host and nectar annuals/perennials in landscape beds, and yes, planting native fauna friendly shrubs like vitex, firebush, and American beautyberry are all part of maintaining a pollinator-friendly yard! Plant one (or several) today! For more information on creating pollinator habitat in landscapes or any other horticultural topic, contact your local UF/IFAS County Extension Office.
As a boy I remember our St. Augustinegrass lawn. I fondly remember winter annual weeds in that lawn.
Many of these so called “weeds” are native wildflowers. And a number of pollinators use these wildflowers.
To see clumps of winter annuals in our yard and in neighbors’ yards was a natural part of the transition from winter to spring. They added interest to the lawn. It was expected to see henbit with its square stiff stems holding up a display of small pinkish purple flowers in late winter to early spring. A clump of henbit was a great place to hide an Easter egg, especially a pink or purple one.

Wild geranium offered another good hiding place for eggs with its pink to purple flowers. Large clumps of annual chickweed would nicely hide whole eggs. Green colored eggs would blend with chickweed’s green leaves.
Crimson clover with its reddish flowers, hop clover and black medic with their bright yellow flowers provided good hiding places for Easter eggs. Plus, clovers add nitrogen back to our soils.

The lawn was healthy and thick enough to limit summer weeds. But during fall and winter, as the lawn would naturally thin and go dormant, these winter annuals would run their course.
I remember the clean smell of freshly mowed grass in spring with the first mowing. Once mowed and as the heat took its toll, by late April or mid-May, these winter annuals were gone. What was left was a green lawn to help cool the landscape as the weather warmed. The lawn was mowed high as St. Augustine should be, watered only occasionally during dry periods, played on and typically not worried with.
Most lawns have winter annuals that let us know spring is near. Perhaps we worry too much with these seasonal, temporary plants that may have wrongly been labeled as weeds. Besides, how long have we been doing battle with them and they are still here. Most lawns have winter annual seeds that await the cooler temperatures and shorter days of early winter to begin yet another generation. By May they are gone.
UF/IFAS Extension agents in the Florida Panhandle are asking you to join in on “No Mow March” in 2023. The idea is to holdup on mowing until the calendar flips to April, allowing pollinators to enjoy these common winter annuals.
Here is a website with more information on No Mow March. On this site, you’ll find a link to sign up to be a participant, check out what Okaloosa and other counties are doing by clicking on “Events” and see more about pollinators, all on this site.
Need an excuse to not mow your lawn this month? UF/IFAS Extension agents in the Florida Panhandle are asking residents to skip their soon-to-be-weekly outdoor chore until the calendar flips to April.
The idea for “No Mow March” is borrowed from “No Mow May,” a concept begun in the United Kingdom that has now spread to northern parts of the United States.
“Obviously, our lawns are growing way too quickly by the time May rolls around,” said Beth Bolles, UF/IFAS Escambia County horticulture agent who is leading the pilot effort this year. “Here in North Florida, March is our transition period, when grass is exiting dormancy. But it’s also when pollinators are starting to become more active, so it’s the perfect time to celebrate them and promote their health and habitat.”
Bolles is quick to point out, though, that the month is about more than just turf.
“We recognize that some communities have rules to follow regarding their lawns,” she said. “There are other things you can do to encourage pollinators to visit, whether it’s container plants or adding new shrubs or pollinator houses. We encourage everyone to find their own way to participate.”
The first step in participating is to sign the pledge at go.ufl.edu/NoMowMarch. Visitors can also use the website to find virtual or in-person events geared to the topic, learn tips for adhering to homeowners association guidelines while still promoting pollinators, and record observations to a No Mow group on iNaturalist.
