Zinnias are well-known annual flowers, primarily recognized for their easy and fast growth. Their wide range of growing habits contributes to their popularity, as they can range from short and bushy to tall with a singular stalk. Regardless of their growing habit, Zinnias are prolific bloomers. They belong to the aster family and are native to Mexico and Central America, thriving particularly well throughout the South.

Zinnia Characteristics
There are three distinct types of Zinnias based on floral structure: single, double, and semi-double. The different floral structures do not necessarily correlate with plant habits. ‘Single’ refers to flowers that have only a single row of petals, with the center of the flower clearly visible. ‘Double’ Zinnias have multiple rows of petals, and the center is not clearly visible. ‘Semi-double’ cultivars exhibit a combination of traits, with flowers having multiple rows of petals while still maintaining a clearly visible center.
Pollinators and Zinnias
Zinnias are great for attracting pollinators, especially butterflies. Interplanting zinnias between rows of vegetables or as a border around vegetables is a great way to attract more pollinators to your garden. There are a few guidelines available for attracting butterflies to your yard using zinnias. The taller varieties are better than dwarf or compact cultivars, and those with wide, flat blooms provide a larger landing surface. Flowers should have prominent yellow centers (disc floret); double bloom varieties make it difficult for butterflies to access nectar. It is also possible that some varieties attractive to butterflies produce a larger quantity of and/or better-quality nectar than others.

Planting Zinnias
Zinnias perform better in garden beds than containers and, due to their ability to grow so quickly, can be direct seeded. To direct seed, the soil temp should be at least 70 degrees and plant the seeds at 1/4’” deep. Zinnias can also be planted as transplants and should be done once the soil warms to 60 degrees. Plant spacing can be anywhere from 8 to 12 inches depending on the plant’s habit. Singular stalk varieties can be planted closer together and bushier varieties should be given more space. Zinnias prefer full sun and well-drained soil. For longer flowering, remove the old blooms.
Zinnia Management
When planting zinnias, it’s recommended to incorporate a general-purpose fertilizer with equal parts nitrogen, phosphorus, and potassium into the soil. Following planting, monthly fertilization with a phosphorus-rich fertilizer is advisable to encourage continuous blooming. Maintaining adequate moisture is crucial for zinnias but avoid overwatering as they thrive in moderately dry conditions. To prevent fungal diseases, water only when the top 1-2 inches of soil are dry, focusing on watering the base of the plant rather than the foliage whenever possible. Powdery mildew is a common issue with zinnias, but it can be managed by applying a fungicide when necessary. However, it’s best to prevent this problem by ensuring good air circulation and avoiding wet foliage.

Zinnias as Cut Flowers
Zinnias, known for their vibrant charm, make delightful cut flowers that can brighten up indoor spaces for a week or longer. For optimal longevity, harvest the blooms when their centers are just beginning to unfurl fully. Trim away lower leaves and promptly place the cut ends into water-filled vases. Regularly refreshing the water helps prevent the growth of algae. When it comes to drying zinnias, double-flowered varieties are preferred as they tend to maintain their shape better than single forms. While all colors undergo slight changes during drying, cutting stems at their peak, removing leaves, and hanging them upside down in bundles away from direct sunlight facilitates the drying process effectively.
In the realm of pollinator-friendly plants, Sweet Alyssum (Lobularia maritima) often flies under the radar despite its remarkable qualities. This delicate flowering plant, with its clusters of tiny blooms, not only adds beauty to gardens but also serves as a vital resource for pollinators.
An exemplary instance is the hybrid series, Easy Breezy™, known for its compact size and remarkable heat tolerance, allowing it to thrive well beyond the spring season. Available in white, pink, and purple variations, this cultivar stands out. Another hybrid, known for its exceptional heat tolerance, is the white-flowering Lobularia ‘Inlbusnopr’, frequently marketed under the trademarked name Snow Princess®.
Let’s explore the many benefits of sweet alyssum as a pollinator crop and why it deserves a place in every garden.
Attractiveness to Pollinators
Sweet alyssum’s petite blossoms, exude a sweet fragrance that acts as a magnet for bees, butterflies, and other pollinating insects. Its nectar-rich flowers provide a vital food source for these creatures throughout the growing season.

Extended Blooming Period
One of the standout features of sweet alyssum is its prolonged blooming period, which often lasts from spring through fall in favorable climates. This extended flowering season ensures a consistent supply of nectar for pollinators, especially during times when other floral resources may be scarce.
Low Maintenance and Versatility
Sweet alyssum is renowned for its adaptability and ease of cultivation. It thrives in a variety of soil types and is tolerant of both drought and heat, making it an excellent choice for gardeners seeking low-maintenance pollinator-friendly plants. Whether grown in garden beds, containers, or hanging baskets, sweet alyssum adds charm and functionality to any landscape.
Companion Planting Benefits
Beyond its role as a pollinator crop, sweet alyssum offers additional benefits to gardeners through companion planting. Its compact growth habit and dense foliage act as a natural ground cover, suppressing weeds and conserving soil moisture. Furthermore, sweet alyssum is known to attract beneficial insects such as hoverflies and predatory wasps, which help control garden pests.
Encouraging Urban Pollination
In urban environments where green spaces may be limited, incorporating sweet alyssum into landscaping projects can play a significant role in supporting local pollinator populations. Whether in public parks, rooftop gardens, or community plots, the addition of sweet alyssum provides essential forage for pollinators and contributes to urban biodiversity conservation efforts.
Sweet alyssum’s unassuming beauty and pollinator-friendly characteristics make it an excellent educational tool for teaching about the importance of pollination and ecosystem dynamics. They may be small in stature, but its impact as a pollinator crop is undeniable. By incorporating this humble yet vital plant into our landscapes, we can create havens for pollinators and contribute to the preservation of biodiversity for generations to come. Let us embrace sweet alyssum as the unsung hero of pollinator crops.

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!
Bright color is sometimes hard to come by in landscapes, especially in those areas where not much likes to grow. In particularly sandy areas along our coastlines, it can be a challenge to find plants that can both tolerate extremely dry conditions with heavy salt spray and provide an aesthetic boost. Luckily, there is at least one flower out there that goes above and beyond when it comes to beauty.
Gaillardia pulchella, or blanket flower, Indian blanket flower, firewheel, or sundance is a relatively low growing (up to 1.5 feet tall) plant that favors conditions that would make most plants wither. It grows as an annual or short-lived perennial and though it goes dormant in the winter, during warm weather, it’s bright and colorful! It is native to the United States, but probably never spread farther east than Texas until assisted by humans. It grows well throughout Florida, and can often be seen along roadsides.

Spreading to around two feet wide, each individual plant may not blanket the ground, but it readily produces seed which is easy to germinate. Flowers are produced throughout the growing season. Varieties are available with different appearances, though all tend to be some combination of bright yellow and dusky red. The blossoms can be used as cut flowers, or left in the landscape to attract pollinators.
Blanket flower prefers well-drained soil, even growing out into beach dunes. As stated previously, it may be propagated easily by seed; either let dried seed heads remain on the plant long enough to drop seeds or harvest them to plant elsewhere. Sow seeds in the spring and enjoy low-maintenance color for months after!
Since Ponce de Leon first set foot in Florida around Easter in 1513 and gave the state its name – he called it La Florida, which loosely translates to flowery in English – Florida has been known for its amazing native wildflower displays. Florida’s primary native flower shows do indeed occur in the spring (the one observed by Ponce de Leon) and fall, but my favorite Florida “wild” flower is neither a native nor does it bloom in April or October. Rather, the Philippine Lily (Lilium formosanum) does its thing each year in the heat of the summer, when not much else wildflower-wise is blooming.
Hailing from Taiwan and the Philippines but naturalized throughout the Panhandle, the Philippine Lily is easy to spot. Often confused with Easter Lily (Lilium longiflorum), which blooms much earlier in the year, Philippine Lily blooms mid-July to August and sports classic lily-type flowers held high on study stems that may reach 7’ or higher. Emerging from the drab green of the surrounding summer landscape, Philippine Lily’s very large (10” or more), very fragrant, trumpet-shaped, creamy-white flowers are showstoppers. The propensity of the flowers to appear in elegant, “nodding” clusters of a dozen or more also adds to the effect. Admired by gardeners and other passersby during the day, at night these wonderfully scented flowers become a whirring site for evening pollinators, particularly the enormous Hummingbird, or Sphinx Moth.

In addition to being a beautiful surprise in natural areas, Philippine Lily is among the easiest and most versatile of landscape plants to grow. The species prefers partial shade, but the thousands growing along roadsides in full sun speak to its adaptability. It is also right at home in our often dry, sandy Panhandle soils, and no special soil amendments are needed for the species to thrive. To get plants started, one may use either seeds or transplants from existing stands. If using seeds, simply sow them in your desired garden location into loosened garden soil, cover lightly, and water – the same seed sowing method can be used in pots for transplanting or sharing with friends later. Alternatively, you can dig or pull bulbs from natural areas where Philippine Lily already exists – assuming you have permission from the property owner. These newly dug and planted Lilies will need babying with regular water for several weeks to reduce transplant shock and improve survival.
Philippine Lily is probably best sited in the back of landscape beds to take advantage of the plant’s height and display its flowers over lower growing perennials. Siting in the back also allows pre and post bloom Philippine Lily stalks to hide amongst other plants as they don’t add much aesthetically when not in flower. Philippine Lily pairs very well with other low-maintenance summer-blooming perennials like Black-Eyed Susan (Rudbeckia hirta), Garden Phlox (Phlox paniculata), Milkweed (Asclepias spp.), and others.
While not a native wildflower, Philippine Lily certainly adds to North Florida’s reputation as La Florida! They are among the easiest to grow, highest impact “wild” flowers Panhandle gardeners have at their disposal. Enjoy them this summer in natural areas and consider adding a few to your landscape!

Begonias have long had a reputation of being either boring workhorses in annual planting beds and container gardens, like Wax Begonias, or finicky, greenhouse specialty types unsuitable for most people and landscapes, like Rhizomatous Begonias. However, in 2008, Benary Seeds introduced a new early flowering landscape/container Begonia series, all with huge, showy flowers and robust growth habits. They named the series ‘Big’ and changed Begonia’s negative narrative forever.
The first attribute that’s obviously different about ‘Big’ Begonias is that they are, in fact, much bigger than “normal” bedding begonias in every conceivable way. ‘Big’ grows to 18” high with a similar spread, roughly twice as large as conventional wax begonias. ‘Big’ also sports massive (for a Begonia) 1.5-2” flowers that don’t stop until the first fall frost ends the show. And since Begonia flowers appear in clusters, the combined effect of these much larger flowers grouped together is nothing short of spectacular. Even individual leaves are larger on ‘Big’, often hand-sized and coming in various shades of green and bronze, depending on the cultivar.

Speaking of cultivars, the ‘Big’ series has now expanded to include eight different selections, each with slightly different leaf/flower attribute combinations. For example, the ‘Big’ that I am growing this year is named ‘BIG Rose Bronze Leaf’. As you might expect, the plant has dark, bronzish-colored leaves and vivid, rose-pink flowers that together make for a striking combination. Others in the series include such creative names as ‘BIG Red Green Leaf’ and ‘BIG White Bronze Leaf’. Though the names of these cultivars leave much to be desired (come on Benary, step up your name game!), they are all outstanding plants.
Fortunately, growing difficulty doesn’t also increase with plant/flower size and all the plants in the ‘Big’ series are extremely easy to cultivate. ‘Big’ selections, like most other Begonias, prefer partial shade and consistently moist soil, though they can tolerate the occasional dry period due to their waxy leaves. The ‘Big’ cultivars with bronze-colored leaves can even tolerate full sun, which the ‘BIG Rose Bronze Leaf’ sited in a sunny area on my deck can confirm. As with most other long-season flowering annuals, I apply a slow-release, complete fertilizer at planting and then supplement throughout the season with liquid fertilizer to keep them looking their best!
If you’ve avoided Begonias in the past like I did because they just didn’t offer the “wow” factor of other annuals, it’s time to think again. Bigger and truly better in every way than most other begonias, the selections in the ‘Big’ series are definitely worthy of a spot on your patio or in your landscape – plant one today and enjoy eye-catching Begonia blooms all summer long.
