Growing in containers can be one of the most versatile ways to add color, texture and mobility to the landscape. However, gardeners generally reach for finicky annuals to fill their pots with pizzazz. The problem with this strategy is that most annuals and perennials need to be watered constantly, fertilized regularly, and changed out with the seasons. That sounds like a little bang for a whole lot of buck! I and most of the real plant people I know fall squarely in the school of lazy gardening and believe there is an easier, less intensive, and ultimately less expensive way to get the same result. This can be accomplished by thinking outside the box and using an alternative class of plants that can fit the same bill of providing color and texture in pots without the headaches and have been sitting on the shelves right in front of us the whole time, the shrubs.
It is beyond me why shrubs aren’t used as container plants more often. Maybe the reason for the lack of use is pure perception; after all, no one with any sense would plant a giant, coarse green meatball or an enormous antebellum azalea in a decorative pot on their front walk. Recent innovations by plant breeders have left this argument moot though as new introductions of old species have revived interest in the entire group. Many of the best of these new cultivars sport traits perfect for container culture (dwarf growth habit, increased flowering, and interesting texture and form) while preserving the ironclad, undemanding nature of their parent plants. The following are a few of my favorite new shrub introductions for container growing!
- ‘Purple Pixie’ Loropetalum

If interesting architecture is what you require in a plant, ‘Purple Pixie’ must be on display in your yard. This dwarf cultivar of the wildly overused purple shrub Loropetalum chinense has taken the horticultural world by storm. The unique combination of true purplish foliage that only greens slightly in the hottest summer sun, ribbon-like pink spring flowers, and a graceful weeping habit make ‘Purple Pixie’ a winner. Give this plant a medium sized container (at least 12” in diameter), water when the soil begins to dry, fertilize infrequently with a slow-release formulation, site in full sun to partial shade, and enjoy for many seasons to come.
This is definitely not your granddaddy’s Ligustrum. Gone are the rampant growth, sickly sweet smelling flowers, and the aggressive nature of ‘Sunshine’s’ parent Chinese Privet (Ligustrum sinense). ‘Sunshine’ is a sterile cultivar with dwarf characteristics (growing 4-5’ with infrequent light pruning), vivid yellow-chartreuse foliage, and most importantly, no flowers. All ‘Sunshine’ asks of us is plenty of sun, occasional fertilizer and a light haircut once or twice a season! Use this plant to frame a dark flowerbed or in a container as a companion to the previous plant, ‘Purple Pixie’ Loropetalum for an extremely striking combination!

A new take on a landscape standard, ‘Baby Gem’ is an exceptionally compact and slow growing cultivar of Buxus microphylla var japonica. All the same features gardeners love about traditional “full-size” boxwoods remains (tight, formal growth habit, ability to prune into many different shapes and ironclad constitution) but with ‘Baby Gem’ are delivered in a perfect package for a pot. This little “gem” of a plant is perfect for use in a smallish container to frame a formal landscape or to give a sense of order to an informal container garden or border!
So if you’re ready to stop replacing all of your potted plants each and every season, reach for one of these shrubs the next time you are at a garden center. You’ll likely be rewarded with compliments on your creativity, four season interest from the plants themselves, and more time to enjoy being in your garden instead of laboring in it! As always, if you have any questions about this or any other horticultural topics please contact your local UF/IFAS Extension office! Happy Gardening!

Tropical Storm Cindy’s early arrival soaked northwest Florida this month, followed by even more heavy rain. Homes in low areas and along the rivers flooded and suffered extensive damage. That being said, we are just entering our summer “rainy season,” so it may be wise to spend extra time thinking about adjusting your landscape to handle our typically heavy annual rainfall.
For example, if you have an area in your yard where water always runs after a storm (even a mild one) and washes out your property, you may want to consider a rain garden for that spot. Rain gardens are designed to temporarily hold rainwater and allow it to soak into the ground. However, they are quite different aesthetically from stormwater ponds, because they are planted with water-tolerant trees, shrubs, groundcovers and flowers to provide an attractive alternative to the eroding gully that once inhabited the area! Rain gardens are not “created wetlands,” but landscaped beds that can handle both wet and drier conditions. Many of the plants best suited for rain gardens are also attractive to wildlife, adding another element of beauty to the landscape.
A perfect spot for a rain garden might be downhill from a rain gutter, an area notorious for excess water and erosion. To build a rain garden, the rainwater leaving a particular part of the property (or rooftop), is directed into a gently sloping, 4”-8” deep depression in the ground, the back and sides of which are supported by a berm of earth. The rain garden serves as a catch basin for the water and is usually shaped like a semi-circle. The width of the rain garden depends on the slope and particular site conditions in each yard. Within the area, native plants are placed into loose, sandy soil and mulched. Care should be taken to prevent the garden from having a very deep end where water pools, rather allowing water to spread evenly throughout the basin.

Besides reducing a problematic area of the lawn, a rain garden can play an important role in improving water quality. With increasing populations come more pavement, roads, and rooftops, which do almost nothing to absorb or treat stormwater, contributing to the problem. Vegetation and soil do a much better job at handling stormwater. Excess sediment, which can fill in streams and bays, and chemicals from fertilizers and pesticides are just some of the pollutants treated within a rain garden via the natural growth processes of the plants.
A handful of well-known plants that work great in rain gardens include: Louisiana iris, cinnamon fern, buttonbush, Virginia willow, black-eyed Susan, swamp lily, tulip poplar, oakleaf hydrangea, wax myrtle, Florida azalea, river birch, holly, and Southern magnolia.

Salt shear and onshore breezes often cause coastal maritime forests to grow at a slant away from the coast. Credit: Florida Master Naturalist Program
People from other parts of the country often move into Florida with expectations of their landscape beyond its capabilities. Those gorgeous peonies that grew up north or the perfect tomatoes they grew in California seem to wither in the heat or succumb to any number of insect or fungal pests. Adapting to our conditions takes listening to those with more experience, changing old habits or varieties and definitely adjusting expectations. Once you understand what the north Florida climate requires, you might be pleasantly surprised with a bumper crop of lemons or a thriving hibiscus that would never have worked in Michigan.
The same idea applies to landscaping on the beach or near areas of saltwater. Particularly on barrier islands like Perdido Key, Santa Rosa Island, and the coastal islands around Apalachicola, the influence of salt spray and hot, dry, sandy soils cannot be underestimated. If you have ever looked closely at the shape of the mature oak trees on the back sides of sand dunes, you’ll notice they’re shorter and tend to lean and grow away from the beach. This is due partially to the onshore breeze that steadily blows off the water, but also due to a phenomenon called salt shear. Salt shear occurs in areas where breaking waves release salt, which evaporates from water droplets and blows into the landscape. Unless specifically adapted to living in a saline environment, the salt can halt growth of the plants receiving the bulk of the spray. Many plants adapt to this by sealing up any vulnerable growing tips and sending energy for growth to the other side, resulting in a sloped shape. Land further inland from the Gulf will have consecutively less salt spray to endure.
Keep in mind that the soil on a barrier island is highly porous; it does not hold water nor nutrients well. The best option is to look at what grows there naturally, and select some of the most attractive and hardy choices for a home or commercial landscape. Knowing that a residence or commercial business is located within these environmental conditions, the best way to ensure success is to work with your surroundings instead of against them.
Below are a handful salt-tolerant options to consider.
Beach sunflower (Helianthus debilis): The yellow-blooming beach or dune sunflower will reseed and spread along as a hardy groundcover.
Muhly grass (Muhlenbergia capillaris): Muhly grass is a native clumping grass commonly used in Florida landscapes. It has showy pinkish-purple blooms in mid-fall.
Beach cordgrass (Spartina patens): Beach cordgrass is a native grass that serves as a sand stabilizer. While not particularly showy, it can serve as a good foundation plant.
Saw palmetto (Serenoa repens): These evergreen shrubs are extraordinarily hearty and long-lived. They produce a fruit that is an important food source for wildlife.
False rosemary (Conradina canescens): This evergreen shrub blooms purple, attracts wildlife, and is a hardy native species.
Firebush (Hamelia patens): Firebush has long-lasting red blooms that attract hummingbirds and native butterflies.
Blanketflower (Gaillardia pulchella): These colorful wildflowers attract pollinators like bees and butterflies and are extremely drought and salt tolerant.
Sunshine mimosa (Mimosa strigillosa): This ground-running plant has colorful, spherical pink blooms and attracts bees. The delicate leaves of the plant are sensitive to touch, and will fold up when touched.

We may shy away from drama in our lives but drama in the garden is always welcome. One plant series that will be a prominent feature in any garden bed is the Amazon Dianthus series.

Although we normally consider Fall the time to plant dianthus, the Amazon Series developed by PanAmerican Seed company can be planted in Spring for blooms that extend into Summer. This is the combination of two dianthus and the results are plants with striking colors and longer blooming cycles.
The Amazon series comes in a few bright colors including Amazon Neon Cherry, Amazon Neon Pink, and Amazon Rose Magic. Flowers are held on stems about 1.5-2′ tall and foliage is an attractive dark green. Plants are generally low maintenance but be sure to deadhead flowers as they fade. Plants will need rich, well drained soil and full sun.

If you don’t have room for the Amazon dianthus series in your landscape, plants will also grow well in containers to brighten a patio or deck.

Almost every landscape has a problem area where the sun just doesn’t shine and many plants won’t make it, maybe it’s the north side of your house, under a small tree, or tucked away in an oddly-shaped alcove. We all know the same old boring green choices that work well here (Holly Fern, Cast Iron Plant, etc.) but maybe you want something a little bit different, something that will provide a pop of color and interesting texture! Look no further than a recent introduction, a whole-plant mutation discovered from the little-used Grape Holly (Mahonia spp.), aptly named ‘Soft Caress’.
‘Soft Caress’ Mahonia is a beautiful little evergreen shrub from the Southern Living Plant Collection (one of the best of the collection in my opinion) and really is a game changer for full-shade areas. Some of you may remember the traditional Mahonia, also known as Grape Holly, from your grandmother’s lawn. Those plants were coarse, spiny, produced messy purplish berries and often appeared generally unkempt. ‘Soft Caress’ is a major departure from its parent. Possessing finely-cut, deep green, bamboo-like foliage, this plant’s texture really contrasts well with many traditional shady species. As a bonus, ‘Soft Caress’ sends up brilliant yellow-gold flower spikes in the dead of winter, certainly a welcome respite from the other barren plants in the landscape; although in this unusually warm year, the plants are just now blooming in the Panhandle.

‘Soft Caress’ is advertised to grow three feet in height and width, a more manageable size than the larger traditional Mahonia species, but I’m not sure I’d take that as gospel, the three-year old plants (hardly mature specimens) in my parent’s landscape are already that size and show no signs of slowing down. However, I’ve found you can easily manage their size with a once a year prune to slow down some of the more rapidly-growing canes. Be sure to time the prune as soon as possible after flowering is finished as ‘Soft Caress’ blooms only once a year and produces its flowers on the previous season’s wood, just like Indica Azaleas and old-fashioned Hydrangeas.
The uses in the landscape for ‘Soft Caress’ Mahonia are nearly endless. It pairs well with almost anything in a shady mixed shrub border. It works nicely as a foundation plant against a porch or under windows on the north or east side of a house where it will be protected from hot afternoon sun; I have employed a grouping of the plants in this way in my own lawn with success. It even thrives in containers! If you want to show off some serious horticultural design skills, mix ‘Soft Caress’ in a large container on the porch with some like-minded perennials for a low-maintenance, high-impact display that you don’t have to replant each season. All this shrub requires is partial to full shade, moist well-drained soil, and an occasional haircut to keep it looking tidy! If you’ve been struggling to find a plant that’s a little more unusual than the standard garden center fare and actually looks good in shady spots, you could do a lot worse than ‘Soft Caress’ Mahonia. 
As always, happy gardening and contact your local UF/IFAS County Extension office for more information about this plant and other gardening questions!
