The Oracle of Omaha, Warren Buffett, once said “Someone is sitting in the shade today because someone planted a tree long ago.” While that’s all fine and good and I’m happy that the next generation gets to enjoy the things we grew, most of us would like to enjoy shade in our lifetimes too! If you too want to plant your own shade, one of the best rapidly growing shade tree choices for the Panhandle is the majestic Florida native Green Ash (Fraxinus pennsylvanica).

Green Ash is a large (50-100’ tall), oval-shaped, deciduous shade tree native to the entire eastern half of North America, but best of all for those of us craving shade, it grows to its mature height in a relative hurry. While most trees that grow extremely fast tend to be inherently weak and short-lived, this is not the case with Green Ash. Capable of growing 6-10’ in a single year if irrigated and fertilized appropriately and often living well over 100 years, there aren’t many plants in the Panhandle that grow quicker or live longer.
There’s much more to Green Ash than growth rate and life span, however. The tree is also one of the prettiest around. Come on, you didn’t think I’d recommend an ugly plant, did you? A look up into the canopy at different times of the year and one can see the tree’s deep, dark green foliage, good-for-Florida yellowish fall color, and slightly showy light green seed pods. Below, the straight trunk is laced with distinctive diamond-shaped bark that hints at the extremely high-quality wood underneath. Fun fact, Ash is historically the most popular wood used to make baseball bats due to its hardness at a relatively light weight – more MLB home runs have been hit with Ash than any other species!

As a Florida-Friendly plant, Green Ash is fairly low-maintenance and provides many environmental services. The species, like any other plant, requires supplemental water and fertilizer during the establishment period, generally the first year or so after planting, but doesn’t demand much else from gardeners after that. Green Ash specimens in Florida also don’t have much in the way of pest problems (the invasive Emerald Ash Borer has devastated ash populations in northern states but thankfully has not yet been found in Florida). However, as a host plant for several native pollinators, including the Eastern Tiger Swallowtail, Mourning Cloak, Orange Sulphur, and Viceroy Butterflies, you may occasionally find caterpillars munching away on the tree’s foliage. If you can handle a little leaf damage, try to leave any caterpillars alone and enjoy the stunning butterflies they later morph into!
Green Ash is a beautiful, ultra-adaptable shade tree. Though the species prefers moist areas, there aren’t many sites the tree can’t thrive in. Do you have a low-lying area near a swamp or stream that stands in water from time to time? Great! Green Ash will thrive. Do you need a street tree to survive in a harsh environment with a cramped root zone surrounded by concrete? Green Ash will be right at home there as well. Green Ash is simply a classic shade tree with many interesting attributes that improves the look of any landscape it occupies. Plant one today!

A beautiful wildflower that lines the roads and open areas is one of my favorite native pollinating plants. Coreopsis also commonly known as Tickseed was designated our Florida State Wildflower in 1991. It can be found throughout Florida and all 17 species occur in North Florida. Varieties such as Leavenworth’s Swamp (C.nudata), Florida (C. floridana) and Coastalplain (C. gladiata) are found in moist areas and other varieties like Lanceleaf Tickseed (C. lanceolata) and Goldenmane Tickseed (C. basalis) are commonly found in the drier areas of the landscape.
All the varieties of Tickseeds have daisy-like flowers with yellow petals except for the Swamp Tickseed which is more pinkish purple in color. The flower gets its common name by the appearance of the small ovalish seed that has two short spines at one end and looks like a ‘tick’. The most common coreopsis is Coreopsis leavenworthii. This plant can be found in moist pinelands and disturbed sites. You can spot the blooms of bright yellow ray petals with brownish central disk flowers from late spring through late fall. This coreopsis can reach 3 feet in height. It grows like a weed and can quickly establish itself on bare soil. Coreopsis is essentially an annual with our colder winters but produces many seeds that will multiply as long as the plant receives adequate sun and moisture. A special species of coreopsis found only here in the Panhandle is the Chipola coreopsis (C. integrifolia). It is less common and only found along the Chipola River. This 18-24” plant has deep green oval-shaped leaves and deep yellow flowers seen blooming in the Fall, maybe a great time to go kayaking or hiking along the river! The Chipola coreopsis prefers moist soils and some protection from the sun. This variety is so rare that it has been listed endangered by the Florida Department of Agriculture.

Coreopsis is pollinated mostly by small bees and not visited as much by butterflies and other pollinators. They are a great plant to use for a show of color! You can get seeds from your local garden center or from the Florida Wildflower Growers Cooperative (https://floridawildflowers.com). This Florida-Friendly plant is drought tolerant and can be sown anytime from October to January.

Do you enjoy watching a variety of birds and butterflies in your landscape? Have you ever watched squirrels get into the birdfeeder? Children may learn about wildlife by watching through a window. Food, water, cover, and space are four essential elements that will create the best habitat for wildlife. Food could be as simple as adding feeders to attract birds to your yard but having a habitat that sustains them is important. Florida wildlife and Florida native plants evolved together and are often interdependent. It is a must to understand what sustains the species you are wanting to attract to your area. Different species prefer different food/plants. Insects also provide birds a food source for their young.
Water can be bird baths, man-made ponds, and natural bodies of water such as streams, lakes, ponds on your property. When relying on a bird bath for your water supply make sure the water is fresh and clean. Shallow water (1-1.5 inches) is better than deep (over 3 inches). Birds like sloping sides and a textured surface; they prefer to walk into water rather than dive in headfirst. Place the bath 5 to 10 feet from a protective cover like shrubs or trees. This needs to be close enough for the birds to be able to reach safety if there is danger from predators. A small outpost for birds to land on near the bath can help them check for predators before heading to the bath.
Cover will provide a place to raise young and should have vertical layers for animals to use for safety, shelter, and nests. Examples of cover that could be added to the landscape are snags that give food for woodpeckers and nesting perches. Or build your own nesting boxes that are species specific for owls, bees, and bats. All bats eat insects and substantially reduce the number of nocturnal insects in a neighborhood.

Lastly it is important to think of your space. Create large patches of good habitat that span several landscapes or consider working with your neighbors to link the backyard habitats and create a larger area. It is all about the “Right Plant, Right Place” concept and understanding the area you are working with and the possibilities. When you go into the last step of planting and attracting wildlife have a plan and know what you would like to attract. Do your research on what you will need for that wildlife and use your resources, ask your local extension agent for ideas and suggestions!
Many plants in our native landscape provide much of what attracts wildlife and provides them with at least one of the four essential elements. The article “Planting for Wildlife Habitat!” will give you some ideas of plants and trees that do well in the North Florida area and will help to attract the wildlife you desire!

Lost in the sea of more popular and showy spring-flowering landscape shrubs like azalea, spirea, and the like, is an underused, exceedingly tough, and currently flowering Florida native shrub that is deserving of a spot in your landscape, Walter’s Viburnum (Viburnum obovatum).

Walter’s Viburnum, named for English-born botanist turned South Carolina farmer Thomas Walter, who first described the species in the late 1700’s, is a spring-flowering mostly evergreen shrub/small tree native to the Southeastern United States. In its native environment around hammocks, swamp edges, and near-river forests beneath the understory of canopy trees, Walter’s specimens often grow to around 15’ in height, live for more than 50 years, and spread slowly into loose thickets from their extensive underground root system. After covering themselves in clusters of small, showy, pollinator-attracting white flowers in spring, Walter’s produces small reddish-black fruit that are magnets for birds and other small wildlife in summer.
Though this tough, low-maintenance nature and gorgeous pure white March flower display should have seemingly enabled Walter’s to be a standout in the landscape, Walter’s Viburnum languished in popularity for many years as it didn’t fit into most landscapes in its wild form. Not too many folks in modern landscape situations are looking for a thicket forming, unkempt-looking tree! However, with increased breeding efforts aimed at selecting superior dwarf varieties and the rise in interest in using low-maintenance native plants, Walter’s has rapidly gained market share on traditional flowering shrubs in nurseries and yards in across Florida.
These newer dwarf varieties of Walter’s, including standouts like ‘Mrs. Schiller’s Delight’ and my personal favorite ‘Whorled Class’, only grow 3-4’ in height and make an excellent replacement for more commonly planted small foundation shrubs. Why plant a disease-prone Boxwood when you can have a disease-resistant native dwarf Walter’s Viburnum? Why allow your landscape to be saddled with drab Dwarf Yaupon Holly when you could get the same basic effect AND an awesome flower show by planting a dwarf Walter’s? Tired of having to constantly prune those Loropetalum or Azaleas to keep them from hiding the house? I think you know the answer by now; plant a slow-growing dwarf Walter’s!

Both the “wild-type” Walter’s Viburnum and the newer dwarf cultivars are about as low maintenance landscape shrubs as one could want. Though Walter’s normally occurs in shaded understory situations with moist, acidic soils in the wild, it is very adaptable to all manner of landscape situations. The species takes full sun extremely well but will also thrive with shade. It will tolerate very moist soil but, once established, is drought tolerant. I fertilize my Walter’s plants each spring with a general purpose, balanced garden fertilizer to boost growth, but there are many plantings of the species that get by without supplemental fertilizer. Finally, due to the dwarfing nature of the previously mentioned Walter’s cultivars, constant shearing won’t be necessary to maintain a pleasing shape, but they do respond well to pruning when a haircut is needed!
If you’ve been looking to include something a little bit different from the standard spring flowering fare in your landscape but also require your plants to be tough adaptable, try Walter’s Viburnum, especially the cultivars ‘Whorled Class’ or ‘Mrs. Schiller’s Delight’. They’ll be attractive, low-maintenance additions to nearly any Panhandle landscape for years to come! For more information about Walter’s Viburnum or any other horticultural or agricultural topic, contact your local UF/IFAS County Extension office. Happy gardening!

There are many trees that can be a great addition to your space that will provide one of the four essential elements food, water, cover, and space. Persimmon thrives in a wide variety of conditions from wet or sandy soil to lowlands or uplands. Deer actively seek out persimmon trees, eating every fruit that is within reach as well as leaves and twigs in the fall and winter. Other wildlife that enjoys the persimmon trees are squirrel, fox, bear, coyote, raccoon, opossum, and various birds including wild turkey. The nectar from flowers provides a significant food resource for pollinator species like bees. These trees are either male or female and at least 3 should be planted together to ensure pollination. Live Oak is a solid tree that many people in this area said survived Hurricane Michael. It provides acorns for food and deep shade. Black Cherry is a host plant for Red-Spotted purple and Eastern Tiger Swallowtail. Bitter fruit matures during the summer to fall and is used for jams, jellies, or liqueurs. Fruits are highly prized by birds and other wildlife. Wild cherry cough syrup is made from the reddish-brown, fragrant and bitter inner bark. Yaupon Holly is another tree that birds and wildlife feed on the berries throughout the winter when food is scarce. Leaves have the highest caffeine content of any other plant native to North America. Some other trees to consider are Basswood, Red Cedar, Florida Hop tree, Elderberry, Slippery Elm, Sassafras, Chickasaw Plums, and the Toothache Tree.
While yard work is important to maintain an attractive lawn, if done successfully, the resident can spend quality time in other pursuits like watching the wildlife from the front porch.
There are many plants that for the longest time I thought were only a nuisance to the everyday gardener, but I truly learned the phrase “Right Plant, Right Place” with these next few plants that I am going to mention. Smilax is a vine with thorns that is nearly impossible to get rid of and gets into our shrubs and landscape. But in the right place smilax provides shelter and food for wildlife. It has a blue-black berry in the spring and provides medicine, food, and dyes for humans. There are 2 species of smilax that are only found in the panhandle. Dog Fennel is native to fields, woodland edges, and roadsides and can be used as an insecticide and antifungal. It has feather like leaves that are very aromatic. Blackberry can grow wild and it is an all-around amazing plant for vitamins. It’s fruit can help fight cancer and decrease cardiovascular disease. Leaves and bark are useful medicinally and leaves can be used as a tea. The last plant I must mention is the Beauty Berry. It is known for its late fall bright purple fruits called drupes, not berries. This plant attracts birds for food in the fall time in North Florida. The drupes can also be used for jams and jellies. Other plants that are great for attracting wildlife are Spiderwort, Dewberry, and Spanish Needle.
