American Beautyberry Photo by: UF/IFAS
Each fall, nature puts on a brilliant show of color throughout the United States. As the temperatures drop, autumn encourages the “leaf peepers” to hit the road in search of the red-, yellow- and orange-colored leaves of the northern deciduous trees. In Northwest Florida the color of autumn isn’t just from trees. The reds, purples, yellow and white blooms and berries that appear on many native plants add spectacular color to the landscape. American Beautyberry, Callicarpa americana, is loaded with royal-colored fruit that will persist all winter long. Whispy pinkish-cream colored seedheads look like mist atop Purple Lovegrass, Eragrostis spectabilis and Muhlygrass, Muhlenbergia capillaris. The Monarchs and other butterfly species flock to the creamy white “fluff” that covers Saltbrush, Baccharis halimifolia. But, yellow is by far the dominant fall flower color. With all the Goldenrod, Solidago spp., Narrowleaf Sunflower, Helianthus angustifolius and Tickseed, Coreopsis spp., the roadsides are golden. When driving the roads it’s nearly impossible to not see the bright yellows in the ditches and along the wood’s edge. Golden Asters (Chrysopsis spp.), Tickseeds (Coreopsis spp.), Silkgrasses (Pityopsis spp.), Sunflowers (Helianthus spp.) and Goldenrods (Solidago spp.) are displaying their petals of gold at every turn. These wildflowers are all members of the Aster family, one of the largest plant families in the world. For most, envisioning an Aster means a flower that looks like a daisy. While many are daisy-like in structure, others lack the petals and appear more like cascading sprays.

So if you are one of the many “hitting the road in search of fall color”, head to open areas. For wildflowers, that means rural locations with limited homes and businesses. Forested areas and non-grazed pastures typically have showy displays, especially when a spring burn was performed earlier in the year. Peeking out from the woods edge are the small red trumpet-shaped blooms of Red Basil, Calamintha coccinea and tall purple spikes of Gayfeather, Liatris spp. Visit the Florida Wildflower Foundation website, www.flawildflowers.org/bloom.php, to see both what’s in bloom and the locations of the state’s prime viewing areas. These are all native wildflowers that can be obtained through seed companies. Many are also available as potted plants at the local nurseries. Read the name carefully though. There are cultivated varieties that may appear or perform differently than those that naturally occur in Northwest Florida.

There is a lot to be said about early morning or late afternoon walks along a woodland trail in Northwest Florida. With so much to see, hear and smell there is never enough time to take it all in. I would suggest slowing down and look for the many colorful and interesting plants these native plant communities have to offer.
I had the great fortune to meet with a group of plant explores lead by Angus Gholson, botanist and conservationist with a passion to share his knowledge in Washington County many years ago for a 5-hour hiking adventure. We hiked an exceptional longleaf pine forest with immense flora on the forest floor. It was all but impossible to see everything.
We searched for unique and common plants in the Sandhills and Clayhills in the central and northern areas of Washington County. Here are just a few of the plants we saw along our hike and some detail about them.

St. Peter’s-wort, Hypericum tetapetalum is a wonderful Hypericum of the many we have in NW Florida. With its ability to repeat bloom petite yellow flowers from March to November, we often get the chance to revisit these trails at a later date for another chance to enjoy them. Like many repeat blooming natives, there will be weeks of rest periods with no bloom. This shrub will grow to three feet tall allowing the flowers to peak out over other plants in the pine flatwoods.
Shiny Lyonia, Lyonia lucida is another exceptional shrub with many uses. This evergreen can grow in low damp areas or with irrigation in landscapes to 10 to 12 feet tall. When found in pine forest areas they range from 3 – 6 feet tall. This Lyonia produces an attractive small bell-shaped red flower spread across a stem of last years growth similar to blueberry. Flowering can occur between November and June.

Pale Meadow Beauty, Rhexia Marianna brings a soft pink bloom to the pine forest, grass prairies and edge of full sun to part-shade wetlands. With the ability to grow in diverse landscapes in Northwest Florida it can just about show up anywhere, bloom a few weeks and melt back into the natural setting. Seeding is best completed in the fall and consistent moisture is needed for bloom to occur.
All three of the plants in this article can be found at native plant nurseries. Call the nursery well ahead of time to make sure they either have it or can order it for you. Enjoy the outdoors and adventure it has to offer.

Sunflowers, Helianthus spp., are a great choice for gardeners who are looking for some cheerful color in their landscape. Here in Florida, we have the main ingredient for success, lots of sunshine!

Sunflowers are short-lived annuals. The average time between planting and bloom is roughly 65 days. You can typically plant sunflowers in Florida beginning in late winter until early fall. Only the coldest months cause problems, and for most years that’s only November – January. Sunflowers can be planted almost anywhere there is full sun. The major selling point with sunflowers is, of course, the impressive blooms (figure 1). These yellow to sometimes orange or red-petaled flowers develop a central seed disc, with most variety’s flowers having approximately an 8” diameter.
When planting, you may choose to plant in narrow rows with close seed spacing in order to cull weaker plants later. A final row and seed spacing of 2’-3’ is recommended for full height and development of most varieties. However, you may also choose to plant in a bed, using a close pattern as seen in the photo below. In any event, sunflowers are easy to propagate by seed and are very low maintenance. Occasionally, powdery mildew and spittle bugs can be a nuisance. A general garden fungicide and insecticide will help if problems occur.

Sunflowers are available in many varieties, consisting of different color blooms and plant sizes. These sizes range from dwarf (1’-3’) to tall (10’-15’) varieties. You may wish to stake taller varieties at some point, as plants will tend to lean with no wind break in place. Here’s a few garden variety common names to look for: ‘Sunbright’, ‘Sonja’, ‘Sunrich Lemon’, ‘Sunrich Orange’ and ‘Autumn beauty’. Seed companies also have mixes available in packets. For tall plants, ‘Mammoth’ or ‘Skyscraper’ varieties will do the trick.
If you are fond of the sunflower bloom and looking for a groundcover, there are a couple of native perennials that fit this category. Beach sunflower, Helianthus debilis or swamp sunflower, Helianthus angustifolius, are groundcovers/ornamentals for landscapes and thrive in dry, hot climates and in a range of soil types. They also are great pollinator attractors.
For more information on growing sunflowers, contact your local county extension office.

Powderpuff mimosa (Mimosa strigillosa), also called Sunshine Mimosa or Sensitive Plant, is an increasingly popular native plant for home and commercial landscape applications that offers a very show display of puffy pink flowers this time of year!

This Florida native, low-growing groundcover grows no more than eight inches in height, and that would be classified as an extremely vigorous stand. Powderpuff Mimosa is technically a perennial legume, meaning it doesn’t need any nitrogen fertilizer from gardeners.
The groundcover is appealing to the eye with its dark green fern-like leaves. Not an evergreen, the plants fall into a semi-dormant to dormant state during the fall and winter seasons. Powderpuff Mimosa is a very resilient groundcover as well, needing little irrigation, spreading quickly, and co-existing well with turfgrass. Just a few pots of this species transplanted should cover up to 300 square feet in a season. Although it spreads quickly, it can easily be pruned or mowed if it moves into unwanted areas.
Powderpuff mimosa is a great plant for erosion control due to its deep roots. These deep roots also allow for good levels of drought tolerance. There are very few insect or disease problems with this plant, other than the occasional caterpillar. It is a very wildlife and pollinator friendly plant, with honeybees, butterflies, deer, and more all finding it appealing. It’s even considered a livestock forage, as cattle find it palatable.
Looking to plant powderpuff mimosa in your landscape? Any area that gets mostly full sun is just fine. This plant is adapted to a wide range of soils, but particularly flourishes in well-drained, sandy loam soils. Be sure to water regularly, especially to ensure successful establishment in your landscape. Find this wonderful little plant at Florida native plant nurseries!

If you live in northwest Florida or southeast Alabama and have never laid eyes on our wild native carnivorous plants, it is about time! April and early May are the best times to see them in bloom. We have six species of pitcher plants (Sarracenia), the most common being the white-topped (Sarracenia leucophylla). However, they come in multiple colors, from yellow and red to a deep purple, and in different sizes.
One thing they all have in common, though—they eat meat. Carnivorous plants all over the world have evolved in places that left them few other options for survival. These plants are typically found in extremely wet, acidic, mucky soils with very low nutrient levels. Normally, plants uptake nutrients like nitrogen and phosphorus from the soil around them. Not being available in these particular environments, carnivorous plants (or more specifically, insectivorous) developed a way to extract nutrients from insects.

So how does it work? Pitcher plants have a modified leaf, which instead of lying out flat like most plants, is rolled up into a tube, or “pitcher” shape. The inside of the pitcher has a sweet sap, and the walls of the tube are lined with tiny, downward-pointing hairs. Separate from the leaf, the plant has an elaborate flower structure, which attracts insects for pollination. While nearby, these insects are also attracted to the colorful leaf and the sweet sap in its pitcher. The insect will land on the lip of the leaf, then crawl down.

Those sticky, downward facing hairs are a trap, preventing insects from leaving the pitcher. Enzymes—a cocktail of proteins naturally found in many other plants but used creatively here—in the sap break down the bug bodies and convert them to nutrients for the plant. In fact, if you slice a cross-section into a pitcher wall or break open a dried one, you will see countless dried exoskeletons at the bottom of the tube. Several other enterprising species have taken advantage of the pitcher plant’s creative structure. More than once, I have seen tiny spiders spin webs across the mouth of the tube, or small lizards and frogs at the bottom, waiting patiently for prey.
Some of the best places to see pitcher plants in the area—they also bloom in October—are Tarkiln Bayou State Preserve, Weeks Bay National Estuarine Research Reserve, Splinter Hill Bog Preserve, and Blackwater State Forest.

The sight and scent of a wild azalea blooming in the woods can stop you in your tracks! Photo credit: Carrie Stevenson, UF IFAS Extension
From a distance, native azaleas are easily mistaken for honeysuckle vines. With long, arching stamens, you might be tempted to relive your childhood, hoping to pull the pistil from the bottom and find a single drop of sweetness on the end. Instead, upon close observation you will encounter an equally pleasurable but distinctly different scent. The wild Rhododendron canescens, known variously as a mountain, piedmont, or honeysuckle azalea, can range in flower color from white to deep pink. In northwest Florida, you will find it on the edges of swamps, or as I did on the sunny fringes of wooded areas with rich, moist soil. It is in bloom right now (March), along with its cousins, the white-blooming swamp azalea (Rhododendron viscosum) and the brilliant orange Florida flame azalea (Rhododendron austrinum).

Native azalea populations have declined due to wetland habitat loss, and their delightful smell and delicate flowers have made them susceptible to overcollection. Due to these factors, the Florida flame azalea is listed on the state endangered species list and wild azaleas should never be removed from their habitat. Native azalea species attract butterflies and hummingbirds, and are often planted in home landscapes as ornamental shrubs. Be sure you purchase them from reputable dealers that are not collecting from the wild.
