Plant these jewels of the fall garden
Until a cooling thunderstorm moved through southern Ontario yesterday, autumn has been more like an extended summer than the herald of winter. Now, as I walk through the garden on this crisp, sunny day, I marvel at all the colour in the flower borders. It's not the intensely bright colour of summer lilies, irises, poppies and daylilies, but the deeper gem tones of ruby-rose sedums, amethyst ajuga and opalescent anenomes. These jewels of the autumn border are set amongst a background of ever-changing foliage--the bronzing leaves of peonies, the antiqued pink and cream kiwi vines, and the pomegranate-toned branches of euonymous alata.
Come along with me as I walk through the garden, and I'll show you some of my favourite gems of the fall border...
See that blue aster with the topaz eye? It's been blooming since the second week in August--that's over a month of wonderful colour. Aster x Frickartii 'Monch' is his name. He waves in the autumn breezes, and as long as I deadhead the spent blossoms, he'll keep on blooming. At about two years old, his three-foot girth spills out onto the flagstone path, causing visitors to pause on the way to the arbour. Otherwise, he's fairly well-behaved, with not a smudge of mildew on his leaves.
Nestled into the sunny border, Sedum purpureum 'Autumn Joy' has been quietly growing all summer long. Its silvery-blue leaves and spring green flower buds cooled down the bright pink, apricot and yellow lilies and daylilies that bloomed during June and July. Upright and stolid for most of the season, the weight of Sedum's maturing flower heads inevitably leads to "middle-aged spread". This year I think I put in the stakes and twine just in time--no floppy stems yet! One of my gardening books says that sedums are difficult to place in the flower border because of the changing colour of their blooms. I don't seem to have that problem. Throughout the summer,the soft green leaves and flowerheads were the perfect foil for summer flowers. Right now, 'Autumn Joy' is queen of the border. As her flower heads change from rose to copper and garnet, she'll be surrounded by the green, silver and plum foliage of spent summer perennials. And, once winter arrives, the stalky seed heads peek through the drifts of snow. Sedum is truly a multi-season plant.
Over in the woodland garden, the Japanese anenomes are waving at us to come over and visit. Their cheerful porcelain-white blossoms dance and dart in the autumn breezes, towering over the heucheras, tiarellas, and ferns at their feet. Although 'Honorine Jobert' is four feet tall, she's as gracefully lithe as a ballerina. Her companion, 'September Charm' is a rosy-cheeked beauty that I couldn't resist placing with 'Honorine' in the "white" border. (Alright, red mixed with white = pink, so it belongs!) With their low-to-the-ground flounce of leaves and long, slender stems. Anenome japonicas like these easily fit into shady or partially shady gardens. And of course, they flower right now, when it's almost impossible to find a woodland plant in bloom.
