A “Gardening for Pollinator Conservation” Workshop will take place Thursday, October 13, at the UF/IFAS North Florida Research and Education Center (NFREC) in Quincy. Pollinators are important in conserving native plants, ensuring a plentiful food supply, encouraging biodiversity and helping maintain a healthier ecological environment – – – the so-called “balance of nature.” Come learn how you can conserve and promote pollinators in your own garden, all while beautifying your own little piece of Nature.
As in previous years, nursery vendors will be selling pollinator plants at the Oct. 13 workshop, making it convenient for you to put into practice what you learn at the workshop! Registration is just $15 per person and includes lunch, refreshments, and handouts.
When: Thursday, October 13, 8:30 am to 5:00 pm EDT
Where: University of Florida/IFAS North Florida Research and Education Center, 155 Research Road, Quincy, FL. Located just north of I-10 Exit 181, 3 miles south of Quincy, off Pat Thomas Highway, SR 267.
Cost: $15 per person (includes lunch, refreshments and handouts)
Our workshop builds on previous successful pollinator workshops held at Leon Co. Extension last year and in Marianna in 2012. This workshop was developed as a collaboration of county faculty from several extension offices with folks from the Florida Fish & Wildlife Conservation Commission as well as UF/IFAS NFREC. Sponsors helping defray costs include Florida Native Plant Society – Magnolia Chapter, Gardening Friends of the Big Bend, Inc., Mail-Order Natives, and University of Florida/IFAS North Florida Research and Education Center.

The Florida panhandle has a treasure of native wildflowers to enjoy in every season of the year. In the late summer and fall, blazing star, also commonly known as gayfeather, can be found blooming in natural areas and along roadsides. You can also add it to your landscape to provide beautiful fall color and interest year after year.
Blazing star is a perennial that is native to scrubs, sandhills, flatwoods and upland pines; this makes it a tough plant that can endure drought conditions once it is established. It is ideal for a low-maintenance landscape and is a perfect addition to a butterfly or pollinator garden. The butterflies and bees love it!
This beauty grows tall and slender so it is best when planted in masses for an impressive display. This lankiness can result in lodging, or falling over, when the blooms get too heavy but this can be alleviated when grown in masses or with other wildflowers that can support them. The spent flowers will provide your garden with more seed for future years and form a larger colony.

The home gardener can add blazing star as potted plants or by seeding directly into the soil in October in north Florida. Seeds are available from numerous online sources. Before you purchase, however, make sure that the species you select is a Florida native!

In the spring and summer, no one notices the little green shrub hidden among wax myrtle and marsh elder at the edge of the salt marsh. However, if I’m leading a group of students or a Master Naturalist class through the same area in the fall, it’s the first plant people ask about. The saltbush or groundsel tree (Baccharis halmifolia) blooms dramatically in late September and October, with feathery, dandelion-like white “flowers” on female plants. These seeds are dispersed far and wide by the wind. Male plants typically grow side-by-side with females, and produce yellowish, tubular blooms at the same time. Characterized as both a large shrub and a small tree, the saltbush typically branches from multiple trunks and ranges in height from 2-10 feet. The leaves are rough to the touch and slightly succulent, enabling the plant to hold onto moisture in the sandy, hot environments on the uphill edges of wetlands in which it thrives.

The plant is often confused with its near relative, false willow (Baccharis angustifolia), which is typically co-located with saltbush in coastal wetlands. It also blooms white in the fall, but can be differentiated by its slender, almost needle-like (but also succulent) leaves.
Saltbush is not typically used in the home landscape, as some people are allergic and the seeds are poisonous if ingested. Properly planted, however, it is a perfect addition to a butterfly garden because the male plants’ fall flowers provide nectar to numerous butterfly species, including the monarch. Another ideal location for saltbush would be a rain garden or the edges of a stormwater pond. Coastal property owners on the bay or Gulf would find it an excellent addition due to its tolerance of the year-round salt spray. The species is very hardy–tolerant of both wet and dry soils–along with a variety of soil pH levels. Plant saltbush in full sun with at least 3-5 feet between young plants.

If you are looking for a late summer blooming plant that attracts pollinators and survives in a tough spot, dotted horsemint (Monarda punctata) is for you! This native plant thrives in sunny, well-drained sites but will also tolerate moist garden spots. It grows quickly and blooms prolifically – attracting pollinators by the dozens. A plant covered in blooms is very showy and when you go in for a closer look, you’ll see unique flowers.

This plant can get 3 feet tall by 4 feet wide but it is tolerant of pruning in the growing season to keep it tidy and encourage bushiness. Just be sure to prune it before it sets flowers, a good rule of thumb is to prune before the end of June.
Propagation is by division or seed. Few pests affect dotted horsemint.
Florida is home to many gorgeous and desirable native plant species. One to consider for your landscape is the rainlily, Zephyranthes and Habranthus spp. They are easy to care for and are bothered by few pests.

As the name implies, rainlilies do thrive when getting consistent rain or watering. A good soaking rain event will result in blooms within a few days. This love for moisture makes them perfect for rain gardens.

Plant the bulbs or transplants in full sun to part shade in moist but well-drained fertile soil. Let them be for many years in order to form large impressive clumps and that is when they flower the best. You can also separate the clumps every few years to colonize new areas and pass along to others. After the plants bloom they will reliably set seed that you can collect to start rainlilies in other parts of your garden. However, the seeds are viable for only a short time so you should plant them immediately.
For sources of plant material, try your local nursery that tends to carry native plants or through online sources.
The Live Oak (Quercus virginiana) is one of the most iconic figures of the Deep South. Mentioning the words Live Oak invokes all sorts of romantic nostalgia of yesteryear and the reputation is not unearned. In fact, many Live Oaks still stand that were growing on American soil when the first English settlers set foot on Plymouth Rock. They are long-lived, picturesque trees that also happen to be nearly bulletproof in the landscape. Given these factors, it is not surprising that Live Oak is far and away the most common tree included in both residential and commercial landscapes in the Coastal South. However, even the venerable Live Oak is not without its problems; this article will discuss a few of the more common issues seen with this grand species.

Few conditions afflict live oak but when they do, improper planting or cultural practices are usually at play. Observing the following best management practices will go a long way toward ensuring the long-term health of a planted Live Oak:
Remember to always plant trees a little higher than the surrounding soil to prevent water standing around the trunk or soil piling up around it, both of these issues frequently cause rot to occur at the base of the tree.
If planting a containerized tree, remember to score the rootball to prevent circling roots that will eventually girdle the tree. If planting a B&B (Balled and Burlap) specimen, remember to remove the strapping material from the top of the wire basket, failure to do this can also result in the tree being girdled.
Live Oak has few insect pests but there are some that prove bothersome to homeowners. The following are two of the most common pests of Live Oaks and how to manage them:
Typical galling on Live Oak
Galls are cancerous looking growths that appear on the leaves and twigs of Live Oak from time to time and are caused by gall wasps that visit the tree and lay their eggs inside the leaf or stem of the plant. The larvae hatch and emerge from the galls the following spring to continue the cycle. These galls are rarely more than aesthetically displeasing, however it is good practice to remove and destroy gall infected stems/leaves from younger trees as gall formation may cause some branch dieback or defoliation. Chemical control is rarely needed or practical (due to the very specific time the wasps are outside the tree and active) in a home landscape situation.
Black Twig Borers can also be problematic. These little insects seldom kill a tree but their damage (reduction of growth and aesthetic harm) can be substantial. Infestations begin in the spring in Northwest Florida, with the female twig borer drilling a pen-head sized hole in a large twig or small branch and then laying her eggs in the ensuing cavity. She then transmits an ambrosia fungus that grows in the egg-cavity, providing food for the borer, other borer adults, and her offspring that take up residence and over-winter in the twig. The activity of the insects in the twig has an effect similar to girdling; the infected twig will rapidly brown and die, making removal and destruction of the infected branches a key component
In conclusion, though there are a few problems that can potentially arise with Live Oak, its premier status and continued widespread use in the landscape is warranted and encouraged. It should be remembered that, relative to most other candidates for shade trees in the landscape, Live Oak is extremely durable, long-lived, and one of most pest and disease free trees available. Happy growing!
