Philippine Lilies in the Panhandle

Philippine Lilies in the Panhandle

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!  For more information on Philippine Lily or any other horticultural topic, contact us at the UF/IFAS Calhoun County Extension Office.  Happy gardening.

Selecting Wind-Resistant Trees for Hurricane Season

Selecting Wind-Resistant Trees for Hurricane Season

The Pensacola area has had its fair share of rough weather lately. While the recent storms were not hurricanes, the rainfall totals rivaled many tropical storms, and the lighting and wind were disastrous. A tornado caused significant damage, including a tragic death, with more tumultuous weather in the forecast. Our rainy hurricane season has just begun, so it is worth talking about tree selection, management, and preparing for storms.

After the busy 1992, 1995, 1998, and 2004-05 hurricane seasons, several University of Florida researchers undertook an exhaustive on-the-ground project to look at tree damage statewide. Their goal was to determine which species survived high winds, and which trees were the most vulnerable during storms. Their findings were consistent, and have held up over the past few decades. A full description of the project can be found online, along with several publications that go over proper pruning and maintenance of trees, both before a storm and after recovery.

For the “coastal plain” of north Florida, the most wind-resistant species are: live and sand live oaks (Quercus virginiana/Q. geminata), American holly (Ilex opaca), Sabal palm (Sabal palmetto), Southern magnolia (Magnolia grandiflora), bald cypress (Taxodium distichum), Florida scrub hickory (Carya floridana), dogwood (Cornus florida), sweet gum (Liquidambar styraciflua), and crape myrtle (Lagerstroemia indica). The live oaks and sweet gums do have a tendency to lose branches, so it is important to undertake proper pruning in the off season to trim up potential problem limbs.

Live oaks, and sand live oaks (which live on coastal sand dunes) are slow-growing trees with extraordinarily dense wood. This protects them in hurricane-force winds. Part of the working theory on why bald cypress, holly, and magnolia do well in storms is their pyramidal shape, which seems to allow wind to whip circularly around the trees and avoid damage. Sabal palms are botanically considered part of the grass category and not trees, so their single, flexible trunk allows them to handle the onslaught of wind. Sweetgums are particularly hardy in tornadoes, due to their sturdy root system and shorter, “stout” branches. Smaller understory trees like crape myrtle and dogwood are likely dodging the strongest winds, but also have strong branch structures and dense wood. These two species, along with sand live oak, also lost an average of more than 80% of their leaves. This defoliation is an adaptation to heavy winds, with trees that lost leaves performing better overall than species that held onto their leaves but toppled at the trunk.

The least wind resistant species, according to the studies, included: sand pine (Pinus clausa), loblolly pine (Pinus taeda), and spruce pines (Pinus glabra)laurel and water oaks (Quercus laurifolia/Q. nigra), Southern red oak (Quercus falcata), Southern red cedar  (Juniperus silicicola), Carolina laurelcherry (Prunus caroliniana), black cherry (Prunus serotina), Loquat (Eriobotrya japonica), pecan (Carya illinoensis), sycamore (Platanus occidentalis), tulip poplar (Liriodendron tulipifera), Bradford pear (Pyrus calleryana), and red maple (Acer rubrum). A couple of pine species—slash and longleaf—performed in the medium range. In my experience post-hurricane, many of these trees that survived were stressed and ended up with pine bark beetle infestations. Water and laurel oak are common trees in Florida home landscapes, but typically have much shorter lifespans than live oaks. They are faster growing but have weaker wood, and are vulnerable to storms.

Another list of tree survivability was developed for residents in tropical and subtropical regions of the state. If you have friends or family in south-central Florida, be sure to share this information with them.

Besides planting wind-resistant species, the research team shared other observations related to tree planting and arrangement, too. Single trees are more vulnerable than trees planted in clusters, as they protect each other from incoming winds. Older trees, and those with preexisting damage, are more likely to fall. Trees with plenty of space around their roots do better—if a tree is surrounded on two or more sides with buildings or other hard surfaces, they cannot spread adequately. Detailed information on identifying damaged or poorly structured trees, along with maintenance and pruning tips, can be found in the “Urban Forest Hurricane Recovery Program” series of articles written by the UF tree specialists involved in the studies. The publications include good diagrams and photos of specific examples.

Sandhill Milkweed – Attracting Butterflies in the Dunes

Sandhill Milkweed – Attracting Butterflies in the Dunes

Like finding buried treasure on a desert island, walking up on a mound of sandhill milkweed (Asclepias humistrata) may elicit cries of excitement from someone who understands what they’re seeing. And not unlike searching for pirate booty, there’s a bit of danger involved, too—milkweed is highly toxic.

Last month in the dunes of Perdido Key, our Master Naturalist class found robust clusters of eye-catching, pink-tinged leaves, blooms, and buds of sandhill milkweed. Also known as pinewoods milkweed, this variety thrives in dry, sandy soils. It is native to the southeast, found typically in the wilds of Alabama, Mississippi, Louisiana, Georgia, Florida, South Carolina, and North Carolina. Its genus name, “Asclepias” refers to the Greek god of healing—indigenous people have used the plant for medicinal purposes (dysentery treatment and wart removal, in particular) for centuries. The species name humistrata means “spreading,” which describes the growth habit of the plant. Milkweed is highly toxic, so we do not recommend trying any medicinal uses at home! The “milk” part of the common name refers to its sap, which is a thick, sticky, white substance containing that toxic chemical.

As the only food source for the monarch caterpillar, healthy milkweed plants are crucial for maintaining populations of the famous monarch butterfly.  The plant itself is rather complex and beautiful. Its five-petaled blooms grow in tight clusters, on stalks sticking several inches off the ground. The leaves are broad and a deep forest green, edged in the pale maroon/pink of the stems and flowers. The seedpods of milkweed are quite large (3-6” long), resembling pea pods and full of seeds. Each seed has a wispy white fiber attached, which helps it disperse in the wind like a dandelion. The fibers have been used for years as stuffing for pillows and mattresses, and were used for life jackets during World War 2.

The first cluster of milkweed we found was host to multiple monarch caterpillars, recognizable by their greenish-yellow, white, and black stripes. By the time you see caterpillars, the milkweed is already working its magic, transferring its toxins to the insects but causing them no harm. Monarchs have evolved the capability to digest and metabolize this poison, which would induce heart attacks in nearly any vertebrate animal.  Adult monarchs use several nectar sources, including milkweed flowers, and females lay their eggs on the plant so that their young can begin eating once hatched.

In the animal kingdom, red and orange are signs of danger.  The bright orange coloration of an adult monarch butterfly serves as a warning to would-be predators to exhibit caution, as the toxins from their food sources stay within the butterfly’s body. The copycat viceroy, soldier, queen, and Gulf fritillary butterflies benefit from this trait by using mimicry in their own orange coloration to ward off predators.

Woodland Pinkroot Adds Vibrant Color to Spring Landscapes

Woodland Pinkroot Adds Vibrant Color to Spring Landscapes

This week I have been noticing some of the beautiful perennials blooming at the Jackson County Extension office, and one struck me as especially beautiful. Indian Pink or Woodland Pinkroot (Spigelia marilandica), it turns out, is native to several counties in the Florida Panhandle.

Woodland Pinkroot is a long-lived perennial that has a very showy but short blooming cycle each spring. It thrives in part shade as a small shrublike forb between 2-3 feet tall. Zones 8a and 8b are its native range in Florida and it is often found in moist, sandy, and well-drained acidic soils. This is not a plant that will tolerate salty soils or salt spray, so planting on the coast is not recommended. Additionally, it dies to the ground in the winter, so care must be taken when weeding the garden to preserve this perennial from inadvertent destruction.

This showy native is easy to propagate from seed or root division but not from cuttings. What’s more, it attracts hummingbirds with its tubular-shaped yellow and red flowers. Old flowers may be removed before seed set to extend the blooming season. One advantage for the urban garden is that it is not an aggressive grower but will need some help if competing with other aggressive native plants such as blue mistflower (Conoclinium coelestinum).

This is one plant that I was not aware of until recently as it seems to be not well known even to long-term Florida gardeners. I think that it is a worthy addition to the native or Florida Friendly landscape if one has the right climatic conditions for it to thrive, namely partial shade and well-drained, moist, and acidic soil.

Landscaping in the Panhandle of Florida: Opportunities & Challenges

Landscaping in the Panhandle of Florida: Opportunities & Challenges

Landscaping in the Panhandle of Florida comes with many opportunities and challenges in this diverse plant environment of coastal, flatwoods (aka pine woodland), sandhills, and clay soil areas running adjacent to the Alabama/Georgia lines.  Sandy soil is the predominate soil of the panhandle area from coastal saltwater marshes and brackish bay waters to wetlands and drier well drained quartz sandy soils of the sandhills.  Unique ecosystems can be found in all these areas.  One of the areas with the largest plant diversity is the Longleaf Pine savannahs found in the sandhills.  Now comes the question of landscaping decisions for your residential living.

Understanding your soils and how to improve them where you live is critically important before putting the first plant in the ground.  We live in an area of abundant rainfall and this will impact the chemistry of your soils.  Make an appointment with your local horticulture agent at the University of Florida IFAS Extension office in your county to discuss your soil and landscape ideas.  Taking soil samples will likely be needed. With instruction you can easily collect the samples needed to be sent and received to determine the best options. 

With abundant rainfall, leaching of key nutrients will occur removing base cations that can include potassium (K), magnesium (Mg), calcium (Ca) and others.  This all leads to soils being more acidic in nature.  Nutrient resources may need to be added and checked every 2-3 years, just be sure to follow the soil sample recommendations.  Soils near wetland areas can leach differently than the deep quartz sandy soils of the sandhills.  Adding organic amendments is a recommended practice.  Just how much will depend on your soil setting; talk with your horticulture Extension agent.  Often new homesites and commercial construction areas have soil brought in to raise or level construction locations.  Understanding the movement of water through these newly added layers to the existing soil below will determine drainage and nutrient movement within this site.  It can be confusing making decisions about adding soil nutrients, lime, and organic amendments.

Once all this is settled you can start thinking about how to enjoy this wonderful Panhandle outdoor living opportunity.  Creating living spaces comes in many ways from building patios, porches, decks, outdoor kitchens, and strategically places chairs and benches.  Talk with your family and others who may enjoy these places with you.  Gazebos or barbeque grill areas may be in the plans.  Placing these into the landscape takes planning. Draft designs and think of creative solutions for the site.  Look at the site elevation changes from high areas to low wetland areas.  Will you need “No See Um” screen for the porch to keep out the small insects or install ceiling fans to keep the breeze moving? 

There are many questions to be asked. Create a list to be addressed before beginning a project and then determine the cost.  Enjoy the adventure!

The Florida Trail

The Florida Trail

Most of us are familiar with the Appalachian Trail, the popular hiking route that follows the mountains from Maine for nearly 2,200 miles to north Georgia. But did you know you could set off from Fort Pickens at Pensacola Beach and follow the Florida Trail for over 1,100 miles, all the way to Big Cypress in the Everglades?

Inspired by the Appalachian Trail in the 1960’s, Florida Trail Association founder James Kern started gathering support and planning a route for a Florida trail that would take a trekker through nearly the entire length of the state. By 1983, the Association’s efforts resulted in recognition as a National Scenic Trail, with the path currently winding through the property of over a hundred land management partners. Some stretches of the trail are designated for biking or horseback riding, but the vast majority are intended for foot traffic only. A through-hike of the Florida Trail can be challenging, as the weather, water, and insects can be more intense in our climate than cooler areas. Dozens of people complete the journey every year, and the trail is gaining in popularity. In 2020 and 2021, fewer than 20 individuals were certified as through-hikers. However, last year 47 individuals signed the end-to-end hiker roster online, complete with their “trail name” and hometown. Many hikers are Floridians, but more than half the roster included people from other regions of the United States, and even a couple from Germany.

At the northern terminus of the trail adjacent to Ft. Pickens, hikers will experience a relatively flat, sandy path along the dunes. A bridge crosses a small freshwater pond, then the trail leads to shadier secondary dunes. On a hike this past October, I saw plenty of blooming fall wildflowers, a turtle, a frog, and numerous birds. The Blackwater Side Trail along Blackwater River State Park and Forest consists of a totally different ecosystem, with 48 miles of shady and hillier terrain. This particular stretch connects with the Alabama Trail, which is still being linked together but aims to run the entire north-south length of the state. According to those who have hiked the whole Florida Trail, the most challenging sections include mucky soil through Big Cypress and rocky, uneven limestone and grasses in south Florida. There are plenty of interesting sights and potential hazards, from alligators and black bears to flooded trail routes and pop-up thunderstorms. But the rewards are vast, too, like having the whole trail to yourself most of the time, with opportunities to see rare panthers and a 2,000-year-old cypress tree. Interested hikers can reach out to the Florida Trail Association’s Western Gate, Choctawhatchee, or Panhandle Chapters if you have questions, (including local member Helen Wigersma). These groups help maintain sections of the trail and are a wealth of information. If you’re up for a new adventure this year, you can start a real one right here in our backyard.
