Florida’s diverse ecosystem showcases a remarkable array of native wildflowers that burst into vibrant colors, particularly during the spring season. Cultivating these indigenous blooms not only enhances the beauty of your lawn but also fosters biodiversity. Florida’s spring landscape comes alive with a vibrant tapestry of native wildflowers, each species contributing its unique charm to the natural scenery.

Yellow, a color that beckons pollinators, especially bees and butterflies, is a prevalent hue among these wildflowers. Many have evolved to showcase bright yellow tones, attracting pollinators, and ensuring the vital transfer of pollen for the continued existence of the plant species. In this spotlight, we’ll explore a selection of my favorite yellow-blooming wildflowers: Leavenworth’s tickseed, dune sunflower, and black-eyed Susan.

Leavenworth’s Tickseed

Coreopsis, Florida’s state wildflower, boasts 14 native species flourishing in North Florida. Among these, Leavenworth’s tickseed (Coreopsis leavenworthii), predominantly found in Florida, graces the Panhandle region with its distinctive yellow, daisy-like flowers adorned with dark centers and scalloped yellow ray florets.

Thriving in open areas, flatwoods, and prairies, this annual or short-lived perennial becomes a beacon of color in the spring landscape. Ideal for wildflower gardens, Leavenworth’s tickseed requires adequate space for reseeding, best achieved by planting one to two feet apart in the spring for optimal flowering. The plant quickly establishes itself in moist soils, benefiting from occasional pruning or mowing to encourage a second flush of flowers.

Preferably rooted in sandy, well-drained soil, Leavenworth’s tickseed demands full sun exposure for maximum flower production, with moist soils playing a pivotal role in reseeding and maintaining this distinctive species.

Beach Sunflower

The beach sunflower (Helianthus debilis), also recognized as the dune sunflower, is renowned for its coastal charm and nearly year-round blossoms. Adapting gracefully to both coastal regions and inland landscapes, this sunflower showcases two-inch flowers resembling daisies or sunflowers, boasting yellow petals and brown centers. A captivating trait is its tendency to follow the sun throughout the day.

When cultivating beach sunflowers, it is essential to allocate ample space for their spreading nature. To maximize visual impact, consider planting them in masses, maintaining distances of three to four feet between each plant. As beach sunflowers may become unruly over time, periodic removal of old stems is advisable. Encouraging new plants to sprout from seeds contributes to a healthier growth pattern. Light trims every three months can further enhance the foliage’s vibrancy and overall maintenance. While acting as an annual in freezing temperatures, the beach sunflower generally reseeds itself and displays admirable tolerance to coastal elements, including salt and wind.

For optimal growth conditions, planting in full sun encourages abundant flowering, although the plant can tolerate light shade for part of the day. Preferably, choose well-drained sandy soils, avoiding persistently moist conditions to ensure the overall health and vitality of the beach sunflower.

Black-eyed Susan

Black-eyed Susan (Rudbeckia hirta), a classic native bloom, captivates with its widespread availability and versatile nature as an annual, biennial, or perennial. This resilient plant grows to a height of one to two feet, showcasing rough-textured leaves and deep-yellow aster-like flowers with dark brown disk flowers forming a central dome.

When incorporating black-eyed Susans into your landscape, consider their suitability for mixed wildflower beds, where they effortlessly self-seed in open or lightly mulched areas. Maintaining proper spacing of 14 to 18 inches between plants, vigilant monitoring during extended dry periods, and providing deep watering, when necessary, contribute to the overall health and vitality of these iconic blooms.

Thriving in well-drained soils, black-eyed Susan showcases adaptability to various soil types. Whether exposed to full sun or partial shade, the plant optimizes its blooming potential, enhancing the visual appeal of any landscape.

Encourage Wildflowers in Your Landscape

Selecting native wildflowers adapted to your landscape’s specific soil, light, and drainage conditions is crucial for success. If initial attempts fail, try different species until you find the perfect match, emphasizing the importance of using the right plant in the right place. Thorough watering aids in establishment, but once native wildflowers are established, they generally require minimal irrigation. Avoid overwatering to prevent fungal and rot issues.

Native wildflowers in Florida typically do not need additional fertilization, as it can lead to rapid growth and increased susceptibility to pests and diseases. Embrace the natural resilience of these plants by avoiding unnecessary fertilization. Encourage the persistence of wildflowers by embracing self-seeding, maintaining open, lightly mulched areas for natural germination, and being vigilant when weeding.

Florida’s spring blooming wildflowers, including Leavenworth’s tickseed, beach sunflower, and black-eyed Susan, contribute to the state’s biodiversity. Selecting the right species and providing proper care allows us to cultivate these native blooms and actively participate in conserving Florida’s precious ecosystem.

Creating a Pollinator Paradise: Attracting Bees, Butterflies, and Birds to Your Garden

Creating a Pollinator Paradise: Attracting Bees, Butterflies, and Birds to Your Garden

In the ever growing urbanization of our world today, green spaces are hard to come by but are so essential to biodiversity conservation. Pollinators, such as bees, butterflies, and birds, play a crucial role in our ecosystem by facilitating plant reproduction. Unfortunately, pollinator populations are declining due to habitat loss, pesticide use, and climate change. However, by making simple changes to your garden, you can create an environment that supports and protects your pollinators. In this article, we will discuss ways to turn your garden into a pollinator paradise.

Choosing Native Plants

Native plants are adapted to the local climate and soil conditions, making them ideal for supporting native pollinators. Research native species that thrive in your region and incorporate them into your landscape. Aim for a diverse selection of flowers that bloom at different times throughout the year to provide a continuous food source for pollinators.

Providing Shelter and Nesting Sites

Pollinators need more than just nectar-rich flowers; they also require sheltered spaces for nesting or overwintering. By incorporating features such as brush piles, dead trees, and nesting boxes you are creating habitat diversity for the pollinators. Leaving some areas of bare soil for ground-nesting bees and providing water sources like shallow dishes or birdbaths can further enhance your garden’s appeal to pollinators as well.

Avoid Chemical Pesticides

Chemical pesticides not only can harm pollinators, but they can also directly disrupt ecosystems. Instead of reaching for a spray on the shelf to deter pests, consider using a natural pest control method such as companion planting, handpicking pests, and encouraging natural predators like ladybugs and birds. Certain organic gardening practices not only protect pollinators, but can also promote your garden’s overall health.

Embrace Imperfection

A manicured garden may look appealing, but it can be sometimes inhospitable to our pollinator friends. Create a more naturalistic approach by allowing certain areas of your garden to grow wild. Letting plants go to seed, leaving some leaf litter, and allowing flowers to fade and form seed heads provide valuable resources for pollinators throughout their life cycle.

Educate and Inspire Others

Because pollinator numbers have rapidly declined in recent years, awareness and education of their importance to our ecosystem is crucial. Spreading the word of their importance and how you can contribute to conservation efforts truly helps the cause. UF/IFAS Extension has made great efforts in hosting workshops, giving presentations, and sharing information through newsletters and social media about the importance of creating pollinator habitats. We encourage you, your neighbors, friends, and community members to join in the movement of creating pollinator-friendly gardens and landscapes.

By transforming your garden into a pollinator paradise, you not only enhance its beauty, but also play a vital role in conserving biodiversity. Every flower you plant and every habitat you create contributes to the well-being of bees, butterflies, birds, and other pollinators. Together, we can make a difference and ensure a thriving ecosystem for generations to come.

Blue Blooming Beauties of the Florida Panhandle

Blue Blooming Beauties of the Florida Panhandle

It’s no secret that fall, October specifically, is the best month for wildflower watching in the Panhandle.  From the abundant vibrant yellow-gold display of various Sunflowers, Asters, and Goldenrods to the cosmopolitan bright pinks and purples of Mistflower, Blazing Star, and False Foxglove, local native landscapes light up each year around this time.  However, if you’re lucky and know where to look, you can also spot two species, Azure Blue Sage (Salvia azurea) and Forked Bluecurls (Trichostema dichotomum) that sport that rarest of wildflower hues – vivid blue. 

Forked Bluecurls begins its flower show in late summer, picking up steam in fall, and reaching its peak now as nights get cool and the days grow short.   The species’ flowers are easily among the most unique around.  Each flower has two distinct “lips” – the lower lip is white and dotted with blue specks, while the top is distinctly pure blue – with characteristically curled blue stamens rising to preside over the rest of the flower below.  Though individual flowers are very small and only bloom in the morning, they appear by the hundreds and are very striking taken together.  Various pollinators, especially bees, also find Forked Bluecurls flowers to their liking and frequent them on cool fall mornings. Though the flowers are obviously the highlight, the rest of the plant is attractive as well, growing to 3’ in height and possessing small, light-green fuzzy leaves.   Forked Bluecurls, while not exceedingly common, can be found in sunny, sandy natural areas throughout the Panhandle, including well-drained flatwoods, sandhills, and open, disturbed areas.

The second blue bloomer, Azure Blue Sage, is possibly even more striking in flower than Forked Bluecurls.  Aptly named and blooming around the same time as Forked Blue Curls, Azure Blue Sage is a much larger plant (often 4-6’ in height) and holds its abundant sky-blue flowers high above the surrounding landscape.  Because of their height and their propensity to occur in bunches, Azure Blue Sage’s brilliant tubular flowers are immediately noticeable to passersby and the myriad bee and butterfly pollinators that visit.  Beyond its flowers, Azure Blue Sage is a very unusual looking perennial plant, tall and spindly with dark green, narrow leaves held tightly to square stems, a giveaway of its lineage in the Mint family.  The species can be found in similar areas to Forked Bluecurls – natural areas in the Panhandle that possess abundant sunshine and sandy, well-drained soil.

Both species would make excellent additions to mixed perennial landscapes where the soil and sun conditions were right, as they are exceedingly low-maintenance and have the propensity to reseed themselves from year to year.  Unfortunately, they are rarer in the nursery trade than they are in the wild and can only be found occasionally at nurseries specializing in Florida native plants.  (Visit PlantRealFlorida.org to find native nurseries in your area!)  However, even if you are unable to source a plant for your home, both these somewhat rare, blue-blooming fall beauties, Forked Bluecurls and Azure Blue Sage, are worth searching out in the many State Parks and public natural areas across the Panhandle!  For more information about Forked Bluecurls and Azure Blue sage or any other natural resource, horticultural, or agricultural topic, contact your local UF/IFAS County Extension Office. Happy fall wildflower watching!

Now is the Time for Wildflower Plantings

Now is the Time for Wildflower Plantings

The year is starting to close out and fall is the perfect season to transform a small part of your parcel into wildflowers. It is a concept thrown around quite a bit, and there are numerous reasons to do so. Not only will you provide great resources to our native and introduced pollinator species, but you’ll also create a habitat for predatory and parasitoid insects. These are nature’s hunters who specialize in keeping the herbivorous pest insect species in your landscape in check and can reduce the amount you spend on insecticides throughout the year. There are some tricks to planting and establishing these plantings, but with a little planning, you’ll be well on your way.

Choose your flowers

The first order of business is to select the plants you’d like to grow. The goal should be to have multiple plants in flower simultaneously and spread out through the year as best you can. Use those long-lasting flowers as a mainstay in your garden. These include black-eyed Susan (Rudbeckia hirta), blanket flower (Gaillardia pulchella), and coneflower (Echinacea spp.). Their extended blooms bring color to your landscape for much of, but not the entire year. Winter can be particularly tricky for flowering plants. The cold and shorter days limit your choices. Fortunately, Florida means the “land of flowers” for a reason. Some of our mid-winter bloomers include blue phlox (Phlox divaricate) and lyreleaf sage (Salvia lyrata).

Pick the Site

Once you’ve thought about the plants you’d like to see in your wildflower bed, you must pick the site. Full sun in an area that is not regularly disturbed and is well-drained is best for wildflowers. Full sun allows the flowers to develop more efficiently and thus have better resources available for pollinators. That much light will also enable the bees to begin their work earlier in the day. You’ll need to disturb the soil initially, but it’s a practice you’ll want to avoid in subsequent years. Many pollinators, particularly bees, are solitary and nest in the ground. Leaving the ground intact provides better nesting and another level of support.

Once you’ve selected where you would like your planting, the site must be prepared for planting. Essentially, this involves the removal of grasses and other plant material, which will suck up the resources better suited for your wildflowers. There are numerous ways to accomplish this task, and how you choose to will depend on your philosophy on gardening.

Time to Plant

Now that you’re down to bare soil, it’s time to plant. A no-till drill is a wonderful tool for this with no soil disturbance. They are also quite expensive and require a tractor to pull them, so they’re impractical for the average homeowner. The best option is to broadcast seeds with a drop or handheld spreader in the home landscape. Before loading the equipment, make sure to mix larger and smaller seeds to help with even distribution. If you only have light seed, mix in a bulking agent such as sand to ensure even distribution. Run over the area with a yard roller to push the seed into your soil. Planting in the fall should ensure there is enough rain to aid seed germination, but supplemental irrigation may be needed early in the growth cycle.  

Wildflower gardens make a wonderful addition to your landscape and once established an easy way to add year-round color. For more information, see this Ask IFAS document, or contact your local extension agent for additional information on this and any topic regarding your gardens and more.

Roadside Flowers

Roadside Flowers

As you drive along the highway look out the window at the blooming roadside wildflowers.  Fall is the season of yellow and purple, with splashes of red.

St. John’s Wort (Hypericum spp.), many different “daisies” (Aster spp.), tall and short Goldenrod (Solidago spp.), and “sunflowers” (Helianthus spp.) brighten up the landscape with the many shades of yellow.  Spikes of Blazing Star (Liatris spp.), clumps of False Rosemary (Conradina canescens), and carpets of Moss Verbena (Verbena tenuisecta) add the purple hues.  Here and there clusters of Red Basil (Calamintha coccinea) grab your attention with their fiery color.

Scarlet calamint, also called Red Basil, with its brilliant red flowers, offer a dramatic contract against the backdrop of scrub, sandhill and coastal dunes where the plant naturally occurs in Florida.  They bloom sporadically throughout the year, peaking in the fall with as many as 100 flowers on a single plant.  It is the only Florida native Calamintha species with red flowers, and its flowers are the largest.

When the Spanish Explorer Juan Ponce de Leon landed on the eastern shores in 1513 he immediately noticed the vast wealth of wildflowers and promptly name his new discovery the “Land of Flowers”, which is the translation for Florida.  Habitats throughout the state vary greatly.  Changes in elevation by only a few inches can change the soil and impact the types of plants growing there.  Associated birds, butterflies, and other pollinators change as the wildflower species vary.  Florida has one of the highest biodiversity in the United States.

Learning to identify the roadside wildflowers is the topic of the next Okaloosa County Master Gardener Lecture Series.  Join Dave Gordon on Monday, October 23 at the Okaloosa County Extension 3098 Airport Rd. Crestview, FL 32539 from 10 -11 am CDT to learn about what is blooming along the road right of way and how they may be utilized in the landscape. For more information go to:

American beautyberry

American beautyberry

When beautyberries start producing their eye-catching, bright purple fruit in late summer, we start to get lots of questions. People want to know what it is, where can they find it, and can they eat it? While the berries look good enough to eat, it’s best to leave them to the birds and deer. They are not toxic and were used by Native Americans for a root tea to treat fevers, stomach aches, malaria, and more, but the taste has been described as bitter and mealy. Thanks to a generous volunteer, I am lucky enough to have tried beautyberry jelly. A little (or a lot) of sugar can make most anything taste good—and the finished product is a beautiful, translucent shade of fuchsia.

Even more interesting to me was the revelation that researchers have been able to extract compounds from beautyberry that successfully repel pest insects such as ticks and mosquitoes. The study began about 15 years ago, after a Mississippi botanist with the USDA Agricultural Research Service mentioned to a colleague that his grandfather taught him to rub the crushed leaves of beautyberry on his skin. The technique had been used as a home remedy to prevent mosquito bites for people (and horses) for generations. As a follow up experiment, another group of researchers found these same compounds—callicarpenal and intermedeol—successfully repelled black-legged ticks (which transmit Lyme disease) as effectively as DEET. In the last few years, researchers out of Mississippi have worked towards creating natural insect repellents from the compound that are less harsh on human skin that many commercially available brands.

Aside from its many practical uses, Callicarpa americana is a beautiful native shrub. It has wide green leaves and the brilliant purple berries grow in clusters along its stem. They stay on through late fall and winter in some places, making a beautiful contrast to fall foliage. Beautyberry shrubs can be found in a wide variety of habitats, including sandy and wet soils, full sun, and part shade. Their adaptability makes them a great plant for tight conditions like roadsides or yard edges, but also for nearly any home landscape. The plants can grow to a height of 4-8 feet and spread 3-6 feet wide. The long-lasting berries make them a great wildlife food source later in the cool season than many berry-producing species.
