Container gardening is a good choice for decks, walkways and balconies. There are many types of decorative containers to use, from clay pots to wooden half barrels. Growing perennial plants in pots has the advantage of easy care. Choose perennials that flower year round or ones that give summer blooms. There are many perennials that have beautiful foliage. Change the placement of the containers to take advantage of blooming times. There are many combinations of perennial plants that are suitable for containers.
The dwarf delphinium variety “Summer Morning” grows to a height of 10 to 12 inches and has light pink flowers that bloom in a compact mound. The variegated Jacob’s Ladder called “Touch of Class” is a finely textured perennial with delicate lacy foliage and a profusion of tiny pale blue flowers. It looks good in the mid-height range of the container garden. Coral bells are a perennial favorite that are grown for their beautiful foliage. “Midnight Rose” has leaves which are deep black-purple with pink spots. These flowers also attract butterflies.
Some perennials thrive in the sun and do not need special soil considerations. Coreopsis gives bright yellow or red flowers from early summer to fall. It grows 10 to 15 inches in height, spreads to 14 inches and is a good choice for beginning container gardeners. “Snowcap” is a dwarf variety of Shasta daisy. It grows to 15 inches, spreads 12 inches and has abundant snowy white blooms all summer. The lobelia variety called “Fan Scarlet” is a perennial that also attracts hummingbirds and butterflies.
The classic blue and white Columbine called “Origami Blue and White” is perfect for a perennial shade container garden. It blooms late spring to early summer.
