Container gardens pack a lot of punch in a planter. When you choose plants following the Thriller-Filler-Spiller formula, you will create show-stopping container gardens for your porch, patio or balcony. Following our tips for successful container planting and beginning with the Thriller element, it’s time to add the Filler. The filler gives body to the design, filling the space between the tall Thriller and the trailing Spiller.
Our 5 favorite fillers for spring and summer container gardens
Impatiens in hot and cool shades of pink, purple and red provide contrast to chartreuse coleus and sweet potato vine in the combination above. Impatiens bloom from early spring through the first hard frost and are by nature a very orderly plant, not requiring much in the way of deadheading. If your container will be in full sun, look for Sunpatiens plant tags, as these varieties thrive in the sun.
Begonias come in many varieties, with sweet pink, white or red flowers and glossy leaves. All varieties of begonia, including Dragon Wing and Angel Wing types, like shade or filtered sun. Plant them with another shade lover, coleus.
Proven Winners’ sun-loving petunia is slightly mounded and a vigorous grower. This colorful and versatile performer can be a filler or spiller in a container. Look for more supertunias in Think Pink Flowers in Your Spring Garden.
4. Violas and Pansies
Displaying unstoppable color, pansies and their little sister, violas, show off in all but the coldest and hottest weather. These spring and fall favorites fill containers just as easily as flower beds, and lend their blues, purples, yellows and reds to brilliant container color schemes.
Count on coleus to bring a saturated pop of color and velvety foliage to your container planting. Newer varieties include peach, chartreuse, burgundy and pink tones to pair well with ornamental grasses and bold annuals like zinnias.
