As the hectic pace of spring gives way to summer and the necessary routine jobs around the nursery of grooming plants, watering, and cleaning, it’s a real treat for us to be able to “play” and indulge our plantaholic ways. Truthfully, we do this as often as possible. First, because it’s just plain fun to try different combinations, and, if a planter stays long enough to grow out, you can see the end result and we can explain how we maintained it. It’s a win-win situation for everyone! So, here is a gallery of planting combinations for shade that we’ve put together recently. When combining plants it’s necessary to understand light and water requirements for compatibility. If you know this, the next goal is to pair plants with contrasting leaf shapes, color, and texture. Echoing or contrasting flower colors and shapes will also factor into the design.
For Filtered Sun or Shade…
The first planter for filtered or morning sun utilizes the big white leaves of ‘Garden White’ caladiums, the airy white blooms and leaves of a euphorbia, a ‘Babywing’ Pink begonia, the grassy foliage of Carex ‘Evergold’, and the dark shiny foliage of hemigraphis, or waffle plant. There’s also a touch of a selaginella for a lighter green, low-growing skirt at the edge of the planting. Maintaining this will involve cutting any seed pods from the caladiums, removing any unsightly leaves and watering regularly. 
The next is a simple planting using only foliage for contrasting color and leaves. Grassy juncus, variegated Swedish ivy, a tough alternanthera with reddish purple foliage, and a chartreuse potato vine provide as much color as flowers…and don’t need any deadheading! This combination only needs occasional clipping if necessary and regular watering.
Caladiums and coleus should be go-to plants for continuous color and big, bold foliage. The dark leaved coleus in the very center of this planting will need to be cut back if it has overgrown its companions, and the caladiums will need seed pods removed to ensure the best leaf production. This planter is mostly caladiums and coleus, with the dainty white blooms of a euphorbia acting as a filler plant. Pothos, a common houseplant, will trail over the edge and add even more color to this shady composition. In fact, many houseplants work well in these types of shady container gardens.
Sometimes it’s fun to try a plant that’s more unusual as the centerpiece of a design. In this glazed pot the dark leaf of the Alocasia is a beautiful contrast to the coleus, grasslike juncus, maidenhair fern, trailing torenia, and creeping jenny.
Finally, here’s a simple planting for shade using a begonia and the contrasting leaf and brightness of carex ‘Evergold’, which will spill over the edge of the container. Simple, yet effective. The begonia will continue to bloom with a couple of cutbacks if it gets “leggy.”
Need help with container plantings in sunnier spots? The next post will highlight some of the plantings for sun that we’ve designed recently.
While all caladiums appreciate heat and shade, there are some that can also handle sun, including ‘Red Flash’, the one shown here. These deep red leaves will mingle with the other foliage and flowers, including a copper plant, Acalypha ‘Tahitian Gold’. It was chosen for its yellow foliage to echo the yellow blooms of the thryallis. The acalypha and a red fountain grass will grow up tall, providing a nice backdrop to this composition.
Since it is a restaurant, after all, and ornamental peppers were plentiful in the nursery, those were placed next, just in front of red Dragonwing begonias. Eventually the peppers might be enveloped by the other plants, but until then they’ll contribute their small white flowers and ornamental purple peppers to the mix,
Last, a silver trailing plant. Usually I use silver dichondra for this color because it holds up extremely well in our heat and humidity where so many other silver plants fail. This year, though, I’ve decided to try a new plant…a selection of one that I haven’t had good luck with, but this is supposed to be an improved variety, so we’ll see. It’s a licorice vine, Helichrysum ‘Silver Star’. We’ll keep an eye on this one and hope for the best. It scored high marks in the University of Georgia Athens trial gardens, so I have high hopes!
A testament to its common name of cast iron plant, the aspidistra looked amazingly good considering the bone-chilling temperatures Birmingham dipped to in January. It only needed a few leaves cut out, and no thinning was required this season…probably due to the cold. A heuchera, that had been added in the 
Torenia is an interesting plant, useful in 
These pieces can be used either horizontally, planting along the top, or vertically, like I’ve designed this one, positioning the plants up the planter. Since it could be unsteady if it didn’t have something to stabilize it at the base, I placed it in a pulp planter that I’d covered with a layer of sheet moss. A plastic saucer underneath will protect the floor during its time indoors, then it can be used without the saucer out in the garden or on a patio, porch or other spot that has some shade.
This planting has a variety of houseplants, including nephthytis, used for its lighter green and white foliage, rex begonias for a bit of color, tooth brake ferns and a bird’s nest fern, a new selaginella with white tips called ‘Frosty’, and a large autumn fern in the top with angel vine spilling over the edge with one last, large rex begonia.
However, a friend recently sent a picture she took (mid January) of warm weather caladium bulbs that had been left outside on display racks for sale in freezing temperatures at one of the “big box” stores in town. Now, caladiums grown in pots are so heat loving we don’t even begin to carry them until late April – and advise people not to plant caladium bulbs in the ground until the soil is thoroughly warmed in May.
If you haven’t noticed, 
The emphasis is on foliage, though, and I’ve included curly parsley for it’s fresh green color, a small blue fescue grass, and a shade loving heuchera for this planting. Holdovers from the summer are aspidistra, which I thin out each season, and a tiny leaf green ivy. After planting, I added birch branches to add more height and winter interest. (Branches are an easy way to get color in planters during the holiday – red twig dogwood branches would also be pretty.) While it looks a bit top heavy with the tall aspidistra at first, the parsley and heuchera will add fullness to the composition as it grows in. I’m also trying the Cool Wave white trailing pansies here this year, hoping they get enough sun to bloom well.
This fall Pardis asked if I would also take a look at the planters at Bottega, their other wonderful restaurant.
With 2013 beginning with a wet, cool spring and the rain continuing into early summer, it seemed like we’d been transported into a different universe than Alabama, didn’t it? All the rain may have caused some complacency – everything seems so much lusher than it usually is this time of year…now the heat is here, though, and it seems certain we’ll be entering our usual summer pattern of hit and miss rain showers with lots of warmth and humidity…
Established plantings in your landscape should be doing well, but be aware that new plantings of shrubs, trees and perennials will need supplemental watering this first summer – pay attention to them. The requirement for new plantings is an inch of water each week.
