With the end of summer’s heat comes the beginning of fall’s color. I love asters and fall brings lots of them. A favorite of mine is Aster novae-angliae ‘Purple Dome.’ Nova-angliae is botanical Latin for New England where this aster is most happy. The flowers are a clear rosy-purple and the foliage is a healthy deep green. Height is close to 18 inches to 2 feet and rarely needs to be cut back to keep the plants compact. Purple Dome’s fame comes from its disease resistance, while most asters suffer from powdery mildew, Purple dome isn’t fazed by it! Purple Dome is a good color contrast to Rudbeckias and a great compliment to Sedums.
Much of the charm of Purple Dome comes from its origin. Discovered by plantsman Dick Lighty, former director of Mt. Cuba in Delaware, whose position it was to map and catalog plants of the Eastern piedmont. Always looking for outstanding plants for American gardens, Dr. Lighty found Purple Dome growing in the wilds of the eastern seaboard, in the days before we discussed GE and GMO’s and their impact on the environment. Aster Purple Dome is a great example of natural selection. And while most of my favorite plant picks are chance discoveries, Dick Lighty’s Aster Purple Dome is a classic example of finding good genetics by observing nature. Purple Dome is a simple plant that simply fits in every fall border.

Every spring our gardeners tell us they want to expand their perennial gardens to offer new colors and plants to make them fresh. For those of us that work in the Perennial department, it’s no different. We are always on the lookout for something different or even ‘new to us’. Here are a few Perennials that we think are a must-have in the garden to give you season-long color and interest.

Silene – Early spring bloom of pink on low mounding thick green leaves. Cut back by half after the first flush of flowers wanes in June, to encourage repeat blooming. Attractive to butterflies

Panicum ‘Northwind’- Wow! An unequivocally upright steel blue panicum. ! Wide, thick leaf blades a golden yellow color in the fall, topped in September with attractive narrow plumes.

Veronica Venice Blue – Gorgeous blue spikes of color late spring to mid-summer. Features large, deep blue flowers in spring over bright green, toothy leaves. Benefits from a good hard trim after flowers are finished, in order to maintain a nice tight habit.

Standing Ovation Little Bluestem- A warm-season grass that does well in poor, dry soils. Spikey bluish-green stems and leaves transition to a sizzling display of oranges, reds, yellows, and purplish-browns in the autumn. Also provides winter interest before cutting back in early spring to make way for new growth.

Oenothera Fireworks- Deep bronze foliage and red stems are contrasted by red buds opening to canary yellow blooms in June. The individual flowers may not last for more than a day or two, but they open in succession leaving the plant in continuous bloom. Burgundy rosettes in winter.

Heliopsis Burning Heart – Dynamic yellow-orange flowers are offset by their deep purple foliage. As attractive to butterflies and bees as it is to people, we’ve found this plant really deserves a place in a beautiful border, a cutting garden, or in massed swathes. She stands 4’ tall with dark red-purple foliage and abundant contrasting yellow daisy-like flowers with orange centers. The plant begins blooming in its first year and blooms from June to mid-October.

Echinacea Adobe Orange – Carefree color from a profusion of bright orange blooms that will add excitement to the summer garden. A must-have for sunny beds and borders. Drought tolerant and bred for cold hardiness and compact form with prolific flowering over an exceptionally long season.

Monarda Jacob Cline – Whorls of scarlet red tubular flowers blend perfectly with prairie wildflowers and herbs. Single plants make a great show, but groups heighten the effect. Dark green leaves have an aroma of mint and basil. Hummingbirds love it!

There’s no doubt that hydrangeas can hold their own in the garden. With big colorful blooms and beautiful green foliage, summer’s favorite flower makes a bold statement in any garden.

But, why not pair them with delicate foliage, bold flowers, or subtle ornamental grasses for more variety? If you’re looking for ways to make your hydrangeas pop, even more, try these companion planting tips.

When planting hydrangeas, be sure to use Espoma’s Organic Soil Acidifier for best results.

Foliage

It’s hard to go wrong when choosing a color for companion plants. Try pairing hydrangeas with foliage in different hues of the same color. This adds subtle dimension and almost creates a 3-D effect in the garden.

If your hydrangeas are pink, pair them with Rose Glow Barberry shrubs. The deep pink and purple foliage emphasizes the pastel pink flowers and contrasts perfectly with the green leaves. Try planting Blue Star Juniper alongside blue hydrangeas for a beautiful display. This low-maintenance shrub provides beautiful bluish-green foliage that complements any blue flowering plants.

Flowers

When planting flowers with flowers, timing is everything. Be sure to choose a summer-blooming flower that will blossom around the same time as your hydrangea. You can choose to plant similar hues or bright contrasting colors. If you’re looking to create a dramatic contrast in the garden, choose a flower that comes in a variety of colors.

Begonias and geraniums are beautiful flowers that come in many different shades, making them a perfect companion for hydrangeas. Create a colorful rainbow garden by pairing blue hydrangeas with pink geraniums or white hydrangeas with scarlet begonias.

Grasses

If you want the focus of your garden to be mainly on hydrangeas, opt for more subtle ornamental grasses that simply enhance their beauty. Most ornamental grasses are low-maintenance and easy to grow, giving you more time to spend perfecting your hydrangeas.

Fountain grass is one of our favorites because it provides pretty feathered plumes that dance in the wind. Green and yellow Japanese forest grass also complement hydrangeas very nicely.
