The Best Container Plants for Your Garden

Cannas grow bigger and better all summer, and they're economical choices for containers because even just a few rhizomes can make a large impact. If they're hardy for you, you can leave them in pots year round. If not, dig up the rhizomes after frost has killed the foliage and save them in barely damp peat moss in the basement until spring, when you can plant them outdoors again. The pretty blooms attract hummingbirds, but the large leaves are the real star. You'll find varieties with green, burgundy and even variegated foliage.

It doesn’t get any easier than New Guinea impatiens… just plant them, keep them watered, and enjoy the show until frost finally zaps them. Most New Guinea impatiens are self-cleaning, meaning they drop their spent blooms without any deadheading from you. (Of course, if they’re in containers on your deck, you may have to sweep up fallen petals.)

Other than shade, the most important thing to remember about New Guinea impatiens is to keep them watered — their fleshy stems and leaves droop the instant the soil gets dry. Although they’ll perk back up as soon as they get more moisture, getting too dry too often will stress them, causing fewer flowers and sparse foliage.

These plants love the heat and don’t mind getting a bit dry, which makes them fantastic container plants. Plus they come in a wide range of flower colors. And look for tulip-, rosebud- or cactus-flowered geraniums to give a traditional planting a twist. But don’t forget the foliage! Many geraniums have a “zone” marked off on the center of each leaf.

A silver-leafed rex begonia like ‘Rum Painkiller’ is a great choice for perking up a shady corner. While most cultivars have other colors, such as red, mixed into their leaves, it’s the silver that makes them stars.

When tender sages are packaged in 4-inch pots and lined up along the greenhouse benches at the nursery in spring, it’s difficult to believe that their handful of compact bloom spikes daintily dancing above tidy foliage could make an impact on the garden come fall.

There’s something about papyrus that elevates a container from average to amazing. It must be the tufts of foliage rising from ramrod-straight stems to give a planting structure and size without stealing from the colorful components. Papyrus is perfect for height in a small container -- it stretches tall, but isn’t a space hog, staying narrow in habit. You can even pot up papyrus and move it indoors to save it for next year. It will need some light and may lose leaves, but come spring, set it outside and new sprouts will take off.

Some petunias cascade over the edge of the pot while others are a bit more upright, so be sure to check the tag for size and height when you’re buying starts. You need full sun to keep these annuals blooming and going strong. And every few weeks, snip off a few stems here and there to stimulate side branches — and more flowers.
