The goal and the dilemma, for many homeowners, is to have bloom in the garden all season. That means, after the azaleas have bloomed, hopefully the show isn’t over. How do you accomplish this in Western North Carolina where the blooming season can extend from April to October?

Shrub roses have revolutionized color in the garden. Blooming anywhere from 3x a season to continual bloom, they're more disease resistant and require little care for the color they offer.

1. Don’t make it All about the perennials.

Nothing beats walking through the store’s perennial section. Our buyer, Chris Haggerty, brings in the best perennials for your garden, and our staff displays them like a cottage garden. It’s a great way to spend a lunch hour and even better way to learn your perennials. A walk through the alphabetized aisles shows you what’s blooming now, what’s about to bloom, and what just finished. Think of it as the bloom-line.

For tight spaces or vertical height, consider a vine like this honeysuckle vine. It blooms May-June and then sporadically throughout the season, and bonus, the hummingbirds love it.

Still, don’t forget that trees and shrubs add bloom to the garden, too. After the dogwoods have bloomed out and the azaleas have faded, the woody bloom show isn’t over, though most homeowners assume it is. There are the roses, crapemyrtles, ninebarks, golden rain trees, sourwoods, hydrangeas, abelias, spireas, deutzias, clethra, butterfly bushes, elderberries and more.

Shrubs and trees add blooms and bones to the garden, giving structure for the smaller perennials. They also take up more space. When you’re on a tight budget with a large area to fill, that’s a good thing.

If you’re in a small space, don’t fret. Many shrubs are dwarf size, like Pugster Butterfly bush, which is blooming now. It remains 2’ x 2’ and gives color all summer and butterflies don’t discriminate against the smaller size. And yes, we’re talking about blooms in this blog, but consider shrubs like fothergilla that have spring bloom and fabulous fall color. Or the double-duty shrubs like Encora azlaeas that bloom spring and fall. Many shrubs and trees are a one-stop-shopping experience because they provide color throughout the season (bloom, berries, foliage, fall leaf color, beautiful bark).

Fothergilla’s fall leaf color is something to look forward too after it’s sring bottle-brush bloom.

 2. Make it about the Perennials

As mentioned above, the store is actually a great place to learn your perennials. As the season continues, the plant palette at the store changes, so it’s easy to see what perennials bloom when. Here’s a pdf that gives you perennial bloom by month. And, here’s a slideshow of staff’s favorite summer and fall perennials. 

Shasta daisy is a long-blooming mid-summer perennial that fills the gap between spring and fall. Easy to grow, divide and propagate, this one is a staple.

Few perennials bloom all season, but there are some that do. ‘Rozanne’ geranium, named perennial of the century by the Royal Horticulture Society at the Chelsea 100th Flower Show blooms from spring to frost. Campanula ‘Blue Waterfall,’ a bright, blue groundcover developed by the same folks (Blooms of Bressingham) that gave us Rozanne is also a continual bloomer. Gaura ‘Siskiyou Pink’ and Gaura ‘Whirling Butterflies’ are short-lived perennials (3-5 years) that will bloom continually from spring to frost. Others, like Nepeta ‘Walker’s Low’ blooms profusely in spring and then sporadically the rest of the season. And some perennials, like Helenium ‘Mardi Gras’ start blooming late in the season (mid-to-late summer) and don’t stop until a hard frost arrives.

'Sweet Kate' spiderwort can be cut back in early summer for a fall re-bloom.

Other perennials give you more than bloom. Agastache ‘Golden Jubilee’ has purple blooms and chartreuse leaves which continue to give show after the blooms are gone. Spiderwort ‘Sweet Kate’ has that same color combination and can be cut back when the weather is super hot (July/August) completely for another bloom in fall. Penstemon ‘Husker’s’ Red’ has burgundy leaves that give color to the garden long after the blooms are gone (though it blooms six weeks or more).

Learning your perennials, figuring our what blooms when, for how long, and if it blooms more than once, can take some time and a bit of  study, but what better way to spend a lunch hour than strolling through the perennials? And don’t forget, our staff is there to answer questions and help you find the best perennials for your garden.

3. Yes, Use Annuals

We hear it all the time, “I only want perennials,” customers say. “I don’t want to plant annuals year after year.” If only plants read our tags and bloomed precisely when we wanted them, too. If only weather never interfered by knocking down the garden phlox just when it was starting to bloom. If only the voles would go live at the neighbor’s house. If only.

One of the most beloved annuals., bold red, geraniums, are hard to beat. Drought tolerant, showy, and strong bloomers, these annuals give a big pop of color all season.

Annuals are the answer to the if onlys in the garden. When there is a lull between perennial blooms, or the storms just knocked down your perennial hibiscus, or the beetles have decimated the garden, annuals just keep on blooming. They fill in the gaps between bloom and help create all-season color.

They’re an investment worth the dollars spent for their color and the enjoyment they bring from April through October. For the price, it’s hard to find something else that gives that much pleasure for so long. Use a bloom booster fertilizer on your annuals every 7-10 days to keep them blooming like gangbusters all summer, and sit back and enjoy. Sometimes, they’re the only flowers blooming and behaving in the garden. And, the best part? The fall cleanup is easy. Simply pull annuals up and toss in the compost bin. No cutting back, dividing, or pruning necessary. They add color to the sun or shade garden, and are still blooming long after everything else has faded.

Most importantly, remember that a garden is a work of progress, not a one and done. It takes patience and some thought to create continual bloom in your garden. All the more reason to stop and smell the roses.
