Two years ago, the Escambia Master Gardener Volunteers were gifted with the flowering perennial Sweet Almond bush (Aloysia virgata). It has quickly become a favorite plant of volunteers and garden visitors due to its many attractive features.
Although, Sweet almond bush is not a Florida native, it is Florida-friendly plant for zones 8b -10b. Plants grow very large, from 6-10 feet with branching that can spread out in all directions. In North Florida, plants can be damaged by a freeze but either return from the base or from growing points higher on branches.
One of the best features are the fragrant white flowers spikes that will be present late spring through fall. Many types of pollinating insects will be attracted to the flowers, although sometimes flowers are too high on the plant for many of us to get a good look at pollinator details.

We have plants both in full sun and partial shade that are performing well in the Escambia Demonstration Gardens. Plants do receive water when rainfall is lacking for about 5-7 days (or all of August this year in the Northwest Panhandle). You can shape your plant with a little light pruning during the growing season to keep branches a little more in bounds. Don’t forget to start a few new plants from these cuttings and then share a low maintenance plant with your neighbors.
The Great Southeast Pollinator Census began in Georgia in 2019 with the goals of increased pollinator habitat, teaching the public the importance of insects, and providing useful data to researchers. 2024 is the first year for Florida to be included and we want to support this project with strong participation. View the webinar from the Northwest District Horticulture Team that teaches how to identify pollinators as well as how to collect and submit data for the 2024 Great Southeast Pollinator Census.
Scouting is an important part of keeping pests in check and gardeners are often up to the task. As you routinely enjoy the beauty of your ornamental and edible plants, you are likely to catch a pest sighting before it gets out of control. One insect that may trick us upon first glance into thinking we have a pest is an interesting lady beetle called the Mealybug destroyer.
Lady beetles are one of the most recognizable insects in the garden with their rounded shiny bodies and often bright colors and spots. The adult mealybug destroyer is smaller than a typical lady beetle, about 1/8 of an inch long, with a dark brownish black body and dull orangish head. They move quickly over flowers and leaves in search of food. The larval stage can be confusing because immatures look very similar to mealybugs, one of their favorite prey. Larva have white, woolly protuberances on the body. Whereas pest mealybugs look flatter, the mealybug destroyer immatures have parts that look like soft white spikes.

Why not learn to recognize an insect that eats lots of soft bodied pests on your plants? Once you see one, you will be able to spot these beneficials more often on your favorite garden flowers.

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.

Migratory animals are no stranger to our neck of the woods. Every year, Florida is host to countless creatures as they make their way from one place to another in search of food, nesting sites, or just a change of scene. From hummingbirds to manatees, it can be interesting to watch the annual cycle of nomadic animals.

One of the smaller wayfarers we see year-round, but especially when they migrate south in the fall, is the gulf frittilary butterfly, Agraulis vanillae Linnaeus. They spend the warmer months of the year in the southeastern United States, following frost-free weather as temperatures drop. During the winter, they enjoy the sunshine of peninsular Florida.
The gulf frittilary is a medium-sized butterfly, with a wingspan of 2½–3½ inches. Females are larger than males. It is bright orange in color, with black markings on the top of its wings and silvery-white spots on the bottoms. In its larval form, it is also bright orange in color, with dangerous-looking spines along the length of the caterpillar. Despite their appearance, these do not sting.
The gulf frittilary caterpillar looks dangerous, but won’t sting. Please do not eat it, however.
If given a choice its larvae will feed primarily on passionflower (Passiflora incarnataand related species), but have also been seen snacking on buttonsage. Toxins from passionflower concentrate in the larvae and butterflies, making them poisonous to predators – much like the monarch butterfly and its host plant, milkweed. The insect’s bright coloration serves as a warning that it is not to be eaten.
Keep an eye out for these beautiful butterflies and consider planting a passion vine in your landscape to help them out. The caterpillars may eat the leaves, but in giving them a feast you’ll help them grow into adult butterflies. Once they do mature, they are fantastic at pollinating many of our native wildflowers, further beautifying the world around them.

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!
