Is it just me or does it feels like summer is passing too quickly this year? Here we are at the full Sturgeon Moon, (rising tonight, August 5th,at 8:56 pm EST), and it seems like the warm weather is just getting started in New England. Many song birds begin to flock in August, and some of them even start their migrations south. I associate the Sturgeon Moon with the departure of my beloved wood thrush, and the final weeks of other ephemeral pleasures here in Vermont. Perhaps because we endured such a rainy June, (the rainiest on record in New England), I feel an urgency to soak up as much of this short season as possible, before it fades away.

Ordinarily I slow down a bit in August. Usually, I cut back on work hours during the dog-days, and allow myself long, lazy afternoons in the garden room; lounging about with tart, ice-cold lemonade, books and languid pleasures. Over the years, I developed a habit of slipping into my kayak at day’s end. I came to love spending long summer evenings on the water; paddling to catch the last rays of sunlight and aimlessly floating in the lavender mist. But this year it seems I can hardly catch my breath. There is so much to squeeze in and so little time. Competing demands and rain-delayed projects all seem to be clamoring for my attention at once. I feel like I am still coming into early July, and yet nature is telling me we are in high summer. The garden here at Ferncliff hit its mid-season crescendo this week. Liatris and Black-eyed Susan; Daylilies and Ox Eye; Russian Sage and Veronica; Bee balm and Phlox; the garden is exploding with primary colors, begging me to stop for a moment and to share it with you. And how can I resist? There is an opportunity here…

By late summer, many gardeners begin to ask me how to breathe life into their tired perennial borders. What can I add to jazz up my lilies? Everything has passed by already, how do I add more color to my backyard? I start to hear these familiar questions in late July and early August; when flower beds have become neglected and weedy, wilted and lack-luster. Garden projects that began in May with a great deal of enthusiasm often fall to the wayside by July. Weekends fill up with family picnics, weddings, back to school shopping, days at the beach and vacations. It’s hot outside. No one really wants to think about digging in the garden, and it really isn’t the time for planting anyway.

No. Enjoy the summer while you can. But let me stir your imagination while you make some notes for the future. By the time the weather cools and your weekends loosen-up, garden centers will be advertising fire-sales, and many perennials will be available for a fraction of the cost. Look at your fading garden with a critical eye, and make a list. What you add to your garden in early September will reward you richly next summer.

Start by considering all the possibilities. Let’s begin with some late summer classics. By boldly pairing lavender Liatris, (gay feather), with orange-yellow daylilies, a gardener can reap the benefits of contrasting texture and opposing color. One year I received a generous White Flower Farm gift certificate, which I used to purchase several daylily collections, including their beautiful and reliable Woodside mix. The bold oranges, reds and bright yellows look stunning in combination with Veronica ‘Goodness grows’ or native obedient plant, (Physostegia). My gardens are also home to some spectacular named daylily cultivars from Olallie Daylily Gardens. Lavender-rose colored obedient plant, (Phystostegia ‘Bouquet Rose’), combines well with every lily hue, hot to cool. Similarly, North American native bee balm, (Monarda), strikes a harmonious chord when settled into the garden near Russian sage, (Perovskia atriplicifolia), where they are both frequented by butterflies, bees and hummingbirds. Blues are much less common at this time of the year, but lady bells, (Adenophora confusa), and another bee and butterfly favorite, hyssop, (Agastache), also provide some violet-tinted blue to the garden. And then there is the beloved classic garden phlox. Without a doubt, fragrant phlox is a memorable scent to be enjoyed at its peak on still mornings and humid summer evenings. Variously colored and charmingly old-fashioned, garden phlox should be positioned where it receives ample moisture and airflow to avoid powdery mildew, making it an ideal partner for moisture-loving joe-pye weed, (Eupatorium). Some garden phlox boasts creamy white and green variegated foliage, beautiful when contrasted with Eupatorium rugosum, ‘brunette’. And no summer perennial garden seems quite complete without old-time favorite, black-eyed Susan, (Rudbeckia fulgida x sullivantii); a fail-safe performer in my garden every summer. With so many varieties to choose from, there is a rudbeckia to suit every garden. A stand out in borders, free-seeding Rudbeckia hirta, ‘Becky mixed’, adds a bit of whimsy along the wildflower walk here at my home. Every spring I have to smile as seedlings appear at random, planted here and there by the wind; emerging from the most unlikely locations, even straight from the gravel path. Rudbeckia and her cousin Echinacea, (commonly known as coneflower ), are important, natural food sources for honey bees. I am quite certain if they could ask us, the honey bees would request gardens overflowing with native plants. Personally, I am happy to oblige. Echinacea purpurea is a lovely garden plant. When viewed up-close in a vase, the flower is every bit as dramatic as a Georgia O’Keeffe abstraction. With a costume of orange, spiked cone center piece and bold fuchsia rays pointing out in all directions, it’s hard not to stare at this drama queen. And for cooler spots in the garden, Echinacea purpurea ‘White Swan’ or ‘Fragrant Angel’ are perfect for lending a touch of elegance. This year I have also seen a new double-flowered white form of Echinacea named ‘Coconut Lime’. It is definitely on my list.

Although they have become more popular of late, ornamental grasses are still largely underutilized in perennial borders. Miscanthus sinensis ‘Variegatus’ and ‘Morning Light’ are two of my all-time favorites, and the splotchy green and yellow stripes of Miscanthus ‘Zebrinus’ make a bold statement when paired with primary-colored coneflowers and violet phlox. The contrasting hues and narrow blades of variegated ornamental grass catch the light and play off many perennials and nearby shrubs. All tall grass has a lovely way of swaying in the breeze, but none quite so poetically as buff-tasseled Calamagrostis x acutiflora ‘Karl Foerster’. Last year I positioned Karl along the edge of my wildflower walk, where he adds movement and a delicate shimmer to a solid grouping of Viburnum. Further along the path, fountain shaped Miscanthus sinensis ‘Morning Light’ adds sculptural elegance where the casual meets the more formal entry to my home. Foliage plants such as ornamental grass, along with structural shrubs, help to create the framework for an entire garden. As spring and summer plantings fade and make way for mid-season and early fall perennials, the statuesque form, alluring texture and seductive movement provided by ornamental grass can be key to anchoring a great perennial garden design. Tall grass can also be used as a living screen, concealing unsightly necessities such as compost bins, plastic vents and air-conditioning units throughout the growing season, and into winter.

More experienced gardeners may have already mastered the art season-spanning bloom in their perennial gardens. But even for the most versatile designer, there are always new ways to visually explore the far-end of the seasonal bloom-range. Filipendula ulmaria ‘Variegata’ as well as the lovely Kalimeris ‘Geisha’ and ‘Variegata’ are knock-out foliage plants throughout the garden season. And as an added bonus, these plants provide pale blossoms to cool some of the hotter-hues in the late season border. One of my new garden favorites, yellow wax-bells (Kirengeshoma palmata), adds a pale golden hue to the garden in August, contrasting with the burgundy-violet foliage of closely planted bugbane, (Cimicifuga racemosa ‘Hillside black beauty’). Yellow wax-bells add interest to this spot before the wind-flower, (Anemone), and bugbane come into flower later this month. Other dark hued garden plants, including shrubs such as ninebark, (Physocarpus) varieties ‘Diablo’, ‘Summer wine’ and ‘Coppertinia’, are endlessly useful for bringing out the golden colors of late summer flowers. Eupatorium rugosum ‘chocolate’ and Heliopsis helianthoides ‘Sommersonne’ is a favorite contrasting, late season combination along my walkway.

Combining late season perennials with neutral-hued foliage plants such as Artemisia schmidtiana ‘Silver mound’ helps keep the August garden from becoming too riotous and loud. Spring and early summer blooming favorites, such as coral bells, (Heuchera), and lady’s mantle, (Alchemilla mollis), continue to play an important role in the garden by adding color and texture, holding a perennial bed together at the edge. Gardens designed to include foliage plants such as these rarely look tired, even during lulls in the bloom season.

While I am fairly certain that my schedule will not be be easing up any time soon, I will continue to seek out the pleasures of high summer this month. This week I promise to make time to stop and enjoy my late summer garden as I pass through the wildflower walk each morning, and stroll along the long perennial border on my way to the vegetable garden. I too will be making notes for fall planting this year. Perhaps this cool, wet season in New England will reward us with a warm and vibrant autumn. But for now summer reigns, if but for a few brief weeks, here in my garden home. Enjoy tonight’s full Sturgeon Moon. Happy Gardening.
