For most of the year, yaupon (pronounced “yo-pon”) holly is the nondescript evergreen backdrop to forested areas throughout the Panhandle. But in the fall, these plants are bursting with brilliant red berries. There are 9 holly species native to our area, all with evergreen, mostly oval shaped leaves. Of these, yaupon is among those with the smallest leaves. Members of this species can be distinguished from the similarly sized myrtle-leaved holly by their leaf margins. While myrtle has smooth edges, yaupon has scalloped/serrated edges. Both species sport bright red berries, tasty only to birds and other wildlife.

The leaves, however, have historically been ingested by humans. I’ve tried homemade black yaupon tea, and it is quite tasty. Native Americans throughout the southeast brewed a “black drink” from yaupon holly as a natural stimulant and for use in ceremonies. It is one of just a handful of naturally caffeinated plants that grow in the wilds of North America, and Spanish explorers quickly took up the habit as well. Lore says that overconsumption can lead to stomach ailments, hence the Latin name Ilex vomitoria. By most accounts, however, you’d have to drink gallons of the stuff to actually get sick. Rumors still circulate that this unappetizing misnomer was deliberate, because by the late 1700’s the homegrown American tea was starting to rival popularity of British teas. In addition to tea, Native Americans would use the plant medicinally and also convert the shrub’s typically straight branches into arrow shafts.

Early American settlers drank yaupon tea frequently when tea was hard to obtain from overseas during the Revolutionary and Civil Wars. During the rationing periods of World War II, the American government encouraged the substitution of yaupon tea for coffee and other teas. While it never really took off in the 1940’s, Texas currently has a rapidly growing industry in harvesting the plant. Growers are selling it as tea and as flavoring for a wide variety of food and drink products. To maintain a steady supply of leaves, tea makers often clear landowners’ property of overgrown yaupon shrubs, free of charge. This win-win solution provides an inexpensive harvest, reduces wildfire fuel, and allows native grasses and other open-canopy species to thrive.

For the most part, the plant is considered a nuisance in forested areas. It is one of those woody species that grows up quickly in areas that haven’t been maintained by fire on a regular basis. As a home landscape plant, it works well as an evergreen screen. While it can grow up to 20’ tall, yaupon responds well to routine pruning. Most native hollies thrive in both wet and dry soils, so they are truly versatile. They are also salt-tolerant, drought-tolerant, wind resistant, and provide winter color and food for wildlife in their bright red berries.
Sometimes we just need a little privacy. This is especially true if you live on a busy road or just have annoying neighbors. There are a few things to consider when selecting a screen tree: 1) full-grown size; 2) speed of growth; and 3) aesthetics. With these three factors in consideration, let’s review some screen options for different situations.

Pineapple Guava (Acca sellowiana)
At one time this shrub was hard to find, but it is slowly becoming more available. Pineapple guava is native to South America, but it adapts well to the Florida Panhandle. This plant can reach 10 to 15 feet in height with an equal spread and has a moderate rate of growth, so it’s a great choice when you just need a small screen. Pineapple guava is moderately salt-tolerant and does well in coastal landscapes. As a bonus, the flowers and fruit are edible. It’s hard to find a more aesthetically pleasing large shrub. Pineapple guava is evergreen with leathery green leaves that have grey undersides. This plant can be grown as a large shrub or pruned to be a small tree.

‘Emily Bruner’ Holly (Ilex x ‘Emily Bruner’)
‘Emily Bruner’ holly is a cross between the Chinese holly (Ilex cornuta) and the lusterleaf holly (Ilex latifolia). This evergreen shrub has glossy green leaves. It has a pyramidal growth habit and is listed as reaching 15 to 20 feet tall by 5 to 8 feet wide, however the specimen at the Santa Rosa County Extension Office is about twice that size. ‘Emily Bruner’ holly prefers moist, well-drained soil. This holly has dense, prickly leaves so it does well keeping people out of your yard in addition to buffering sound. The flowers have a sweet scent and are a favorite of honey bees.

Dahoon Holly (Ilex cassine)
Dahoon holly is native to North America, is tolerant of wet, shady sites (but can also handle full sun), and displays some salt tolerance. This evergreen, small tree is somewhat shrubby. It can grow to be 25 to 30 feet in height with an 8 to 12 foot spread. Dahoon holly has nice light green leaves that are smooth, not prickly like ‘Emily Bruner’ holly. It has a moderate growth rate.

Southern Magnolia (Magnolia grandiflora)
It’s hard to beat a majestic southern magnolia in the landscape. Why not utilize it as a screen tree? Now, not all southern magnolias are made equal. There are a few cultivars that do well as screens as well as on their own. ‘Bracken’s Brown Beauty’, ‘Claudia Wannamaker’, and ‘D.D. Blanchard’ are three that come to mind and are readily available in the trade. Southern magnolias can reach up to 80 feet tall and 20 to 40 feet wide depending on cultivar and growing conditions. Not only do these three cultivars have beautiful dark green, leathery leaves, their leaves also have brown undersides. These versatile trees can tolerate are variety of soil conditions and they are very wind resistant. And as another bonus, they have beautiful, fragrant flowers.

Eastern redcedar (Juniperus virginiana)
If your looking for softer texture in your landscape, then you can’t go wrong with a cedar tree. Unbeknownst to its name, eastern redcedar can be found growing all over the United States. This evergreen conifer prefers well-drained sites in full sun. It can grow 30 to 40 feet in height by 10 to 20 feet wide. Eastern redcedars have good salt tolerance. These trees produce beautiful, blue-green foliage. One key to growing this tree successfully is to give it space. Plant trees 12 to 24 feet apart. If using as a screen, you may consider staggering this tree to give it the space it needs.
There are lots of good options when selecting trees for a screen. It’s important you select plants that fit the site. The University of Florida has an excellent plant selection tool found at the Florida Trees for Urban and Suburban Sites webpage.
If you are looking for an interesting native plant that attracts wildlife and makes a statement, look no further than Weeping Yaupon Holly Ilex vomitoria ‘Pendula’. The weeping growth habit with olive green leaves and white bark are attractive year-round. A bonus are the showy bright red berries that attract birds in the fall and winter. It is a cultivar of Yaupon Holly Ilex vomitoria which is tolerant of variable light and soil conditions making it a very adaptable plant.
Weeping Yaupon is a small evergreen tree that grows 15-30 feet tall with a mature width of 6-12 feet. Once established it has a high tolerance to drought conditions and is also able to sustain salt spray making it a good fit for coastal landscapes.
Landscaping with native plants brings opportunities and challenges while adding diversity and beauty to the home. There are many factors that come into play to successfully grow plants. As gardeners, we all want things to look exceptional for all to enjoy. Native plants have evolved over long periods of time naturally in a given region without intervention, bringing much needed diversity to natural areas and landscapes. A big plus for natives are the flowers presented for the local bee populations and other pollinators assisting in the continuation of the plant species potentially established over thousands of years.

Native plants have evolved in natural communities and are found to be interdependent not only plant to plant yet with soil type, soil microbial activity through bacteria and fungus, specific site location and others though biodiversity of these living communities. Part of this community is often referred to as the soil web creating the connections of billions upon billions of organisms in the critical survival of the plants, insects and other animals we see. The first steps when considering native plants for your landscape are to do your research and contact your local Extension office. Some questions to consider may include: Does it grow best in well drained sand or wet soils or require high in organic matter? Will full sun, part-shade to full shade be needed?

Plants that are native and non-native are often seen in the same landscape setting. Consideration should be taken to determine if either of the groups are aggressive in expanding beyond the intended plant setting. Before moving on, non-native is in reference to plants that are introduced to a plant community that came from a totally different plant location. An example of that location being hollies from southeast Asia or South America or even a different area of the United States. Many have been researched and observed for many years under managed situations before being introduced into the local landscape nursery markets. Once in a while a plant is introduced that has not gone through a long rigorous study and can become naturalized outside of its normal plant zones and establish as an invasive species. This highly adaptable aggressive habit can, and often will colonize a given location out competing the native plants. Kudzu is a good example of an invasive exotic plant that is naturalized in the southeastern U.S.
As gardeners there are opportunities to have positive impacts on some of these diminished native habitat areas that can be threatened by growth of urban and rural areas in Florida. Establishing native plants areas into the landscape with proper soil preparation, managed water needs and more gives that chance for this interdependent system of plants, animals and nonliving elements to remain established with big impacts.

Native plants can be a working part of the garden from wonderful flowers, season color change, leaf foliage of multiple sizes and shapes to feed the insects that feed the birds, leaves and nuts that feed so many other animals for us to enjoy seeing. Balance is such a big part of being a successful gardener. Remember not all native plants are suitable for landscape spaces, do your research and ask for assistance from the experts to determine if it is the right plant for the right place.
Shrubs can serve many purposes in a landscape and have been used in both mass plantings and as accent features. They can include plants that offer colorful blooms, food for pollinators, and screens for less than favorable views.
We tend to think that shrubs will be permanent feature in our landscapes, because many are hardy and adapted to our climate. Like any other plant you may choose for your yard, shrubs may not live forever and there are a wide variety of reasons a shrub may need replacement after years of solid performance.
Let’s use any example from my own yard of the Dwarf yaupon holly, Ilex vomitoria ‘Nana.’ Back in 2001, I planted three hollies, spaced with plenty of room to grow, in a border area of my landscape. The plants grew well forming mounds about 3.5 feet high and 4 feet wide. Since the ‘Nana’ holly is a naturally mounding shrub, it did not require pruning and once established, rainfall supplied needed water.

Over the past year, several areas of branch dieback have developed in all plants. After finally deciding that the dieback was unattractive enough to warrant plant removal, I began cutting the plants back. I discovered dead interior branches, girdling roots, and some internal stem discoloration. In other words, there are many factors that have led to poor plant performance. Another issue is a large Loropetalum hedge (planted by my neighbor) that shades one side of the plant.

What could I have done to help these plants stay healthier for many more years? I could have prepared the rootball better for planting by shaving off the edges or supplied a little fertilizer on occasion in my sandy soil. These practices may have extended the life of the plants for several more years, but they may not have made a difference. Sometimes shrubs decline and die. I am accepting that not everything performs at an outstanding level in our climate. Also, there is an end point for some of my favorite plants in the yard. Some may outlive me while others thrive for a few years or a decade or so.
The bright side of loss of my Yaupon hollies is that I get to plan for a feature for the new year. Maybe something for pollinators and birds to last the next 17 years.
