Low-maintenance Perennials

Perennials give us some of the best flowers in the garden. These hardy plants come back year after year getting bigger and better each time. Most perennials take a lot of dead-heading to keep them looking nice throughout their blooming time, but there are a few that are easier to care for. Cut them down when they are done flowering and that’s all the maintenance they need.

Sedum Autumn Joy is a well-known favorite that attracts butterflies. The leaves grow close to the ground, then once a year it sends up shoots topped with soft pink flowers, similar to yarrow. As the days get shorter, the flowers turn a rich rusty red.

Moonbeam Coreopsis produces star-like blossoms of pale yellow with finely textured foliage that is good-looking all season. It blooms from July through October and spreads 18-24” wide.

Black-eyed Susan, Rudbeckia fulgida ‘Goldsturm’, grows into a large clump with 3’ tall golden, black-centered, daisy flowers bloom from August to October.  Seed heads are attractive to birds in the fall and winter.

Stella D’oro Daylily has bright, golden-yellow flowers that bloom throughout the summer above fresh green leaves. It is compact, growing only 16 inches tall, and is good for containers and flower borders.

Purple Dome New England Aster is a compact aster with dark green foliage and profuse bloom of dark purple daisy flowers which can entirely cover the plant in September and October. 

Santa Barbara Daisy, Erigeron karvinskianus, is a low-growing perennial that is covered with little white daisy flowers all summer long. It is tolerate drought once established, and can be used as a border plant or to hang over a wall.

Peonies are easy to grow and give you magnificent flowers in May-June. They come in pink, white and red and live for many years, growing into a larger clump with more flowers each year.

For shady areas, Hostas can’t be beat. With their beautiful foliage in different combinations of blue, green, white and yellow, they will fill the shady bed with their colorful leaves. Hostas also bloom in the summer with spikes of lavender to white, lily-like flowers, which can be quite showy.

Heucheras, or Coral Bells, are one of the most diverse and colorful shade perennials.  Plant them as a groundcover, or intersperse some between other plants. Their round leaves come in many colors from bright green to purples to near black, and they send up delicate spikes of white or coral flowers in the summer.

Helleborus is an iron clad deer-proof plant that tolerates dry shade once established. It blooms very early, in late winter with cup-like, greenish-white flowers. Some varieties have pinkish flowers, but their broad leaves are good-looking all year.

Dicentra, or Bleeding Heart, is one of the easiest perennials to grow in the shade. The pretty little pink flowers in the spring resemble pink and white hearts, and when they are done, the plant turns yellow and dies back. Clean up dead foliage and forget about them until next year.

Fall is a good time to plant perennials. They will get established over the winter and bloom beautifully for you next year.

• Fall is for Planting! Trees, shrubs, lawns, ground covers and bulbs get a jump on spring if you plant them now.

• Keep apples picked up from under the trees to help control the spread of coddling moths which make wormy apples.

• Trim foliage on grape vines to allow more sun to reach the fruit and ripen the grapes.

• Prepare houseplants for return trip indoors. Scout for insects, and thoroughly rinse leaves and container.

Colorful Flowers for Fall

The end of the summer doesn’t have to mean the end of your colorful garden. There are plenty of ways to keep your garden beautiful with fall-blooming flowers. Fall gardening will put you in the spirit of the season, and is a great way to enjoy the beautiful outdoor weather.

The mum, or chrysanthemum, is the first thing that springs to mind when one thinks “fall flowers.” They bring a fresh new look to the fall season and are available in an array of lively colors. They are hardy perennials that come back year after year.

Asters are the other classic fall flower. These 2-3-foot plants pact a lot of punch in the flower bed, blooming with dozens of flowers over a long fall season. They come in various shades of purple and pink and are a fine addition to the perennial border.

Japanese anemone is one of the best of the late summer and early autumn border flowers, with tall upright stems that do not need any staking. In light, airy shade the pink, white or rose-colored semi-double flowers bring a fresh look to the perennial bed. Anemones are sometimes called ‘wind flowers’ and they are indeed graceful swaying in the lightest breeze.

Sedum ‘Autumn Joy’ is an upright sedum growing 2 feet tall. Its thick grey-green leaves are topped with large domes of bright pink flowers in September which gradually soften to a coppery color through the fall. Drought-tolerant and hardy, this is a fine plant for the fall garden, and it is much visited by honeybees.

Another secret for a beautiful fall garden is the use of ornamental grasses. Around Labor Day, they begin to send up dramatic plumed seedheads. These usually begin as silky tassels, then expand into fluffy flags that last well into winter. They are decorative in the garden even after the grasses themselves have dried and gone dormant.

The tough little pansy is another great choice for a fall garden and will still be blooming after all the other flowers in your garden have died off. It will also be amongst the first to bloom again come spring.

Pansies have been bred in a wide range of colors, from soft pastels of yellow, pink and apricot to bright gold and orange though to purple, violet, and blue. They are a hardy plant, growing well in sunny or partially sunny locations. This versatile flower is perfect whether planted in gardens, window boxes, or pots.

Snapdragons are another staple of the fall garden. From low border snaps to tall “Rockets”, these colorful beauties will brighten the garden or your containers this fall and next spring too. They come in a rainbow of colors adding a lot of cheer all around.

Brighten up your landscape with colorful fall flowers.
