It doesn’t take long for a fun adventure at the local garden center or greenhouse to become an overwhelming, hair-pulling experience. With the bazillion plant and pot choices available, it can be difficult to pick just the right elements for the perfect container planting. Oceans of begonias, impatiens, coleus, petunias, salvias, and Cape daisies can leave anyone dumbfounded. Then there are the rows of colorful terra-cotta, fiberglass, glazed, metal, and plastic pots to contend with. It’s not easy when faced with so many options, but don’t let that intimidate you. Rather than wince, embrace the variety and have fun. As with finding the perfect clothes, shoes, and accessories for a special occasion, you have to try a few things on in the store before you find the right outfit. The best way to assemble a winning container combination is not to be shy about mixing and matching plant and container options at the garden center. You’ll soon find a composition that strikes your fancy. Here’s how I go about finding mine.

Go for foliage, not flowers
When putting together a container, I zero in on leaves first. Flowers are nice, but they come and go. If you can assemble a container combination that looks good with the foliage alone, then flowers are a bonus. Plants with interesting foliage can bring structure, texture, or color to the design; the best foliage plants have all three qualities. I like to let the first plant that catches my eye take the lead. I then seek out foliage and flower companions by walking around the greenhouse and holding my prime contender up to other plants. Much like shopping for fabric or matching a shirt and tie, I look for color compatibility.
I have studied color theory and design, but I find it easier to just play and wait for a reaction. When you put plants together, they seem to say, “I want to be with that one” or “yuck, no way.” The combinations we generally like have a pleasing harmony or contrast. Pay attention to intensity, avoiding the combination of too many different pale pastels and saturated pure hues, which can make a combination look chaotic. Likewise, don’t mix together too many different warm and cool colors. Stick with two or three—maybe four—agreeable colors.
When mixing and matching plants, also keep their textures in mind. Choosing a blend of glossy, matte, or fuzzy leaves adds another level of interest, as does combining fine, broad, rounded, or jagged foliage. I like to use contrasting texture to create dramatic container plantings. The hefty, bold leaves of elephant’s ear (Colocasia spp. and cvs., USDA Hardiness Zones 8–11) paired with lacy fern foliage are dynamite together, as are the distinguished leaves of Rex begonias (Begonia Rex-cultorum group, not hardy below Zone 11) with slender fiber-optic grass (Isolepis cernua, Zones 8–10). The key is to choose a variety of textures. Too much of one texture, such as large, chunky leaves, is like colorful pieces of a jigsaw puzzle that don’t quite go together until you find the connecting pieces in the form of fine-textured plants.
1. ‘Excalibur’ caladium (Caladium bicolor ‘Excalibur’, USDA Hardiness Zones 10–11)

4. Creeping wire vine (Muehlenbeckia axillaris, Zones 8–10)
Take a cue from texture
