Pennisetum with Heuchera ‘Caramel’, Cuphea and Calibrachoa
One of the pleasures of container gardening is that you can create fresh arrangements to complement each season?s landscape. The colors of Fall Chrysanthemums have been selected for just this effect, but isn?t it dull to limit yourself to just a single plant? Consider the wide selection of cool season “annuals” that are at their prime in September and October, offering at least 6-8 weeks of color. There are ornamental peppers, salvias, grasses, million bells, abutilons and cigar plants, just to name a few. Don’t forget the perennials with outstanding foliage, like Heuchera ‘Caramel’ and Autumn Fern (Dryopteris erythrosora) which add contrast and can later be transplanted into the garden for next year?s display. And then there are shrubs with fall interest, such as Hydrangea paniculata ‘Little Lime’ (aging blossoms), Cornus ‘Arctic Sun’ , and Ilex verticillata (Winterberry), which will add height and weight to bigger pots. Here are two more tips for pulling it all together.
First, remember to select a variety of bold and fine textures. The bold punch of a large leaved Heuchera, or Ornamental Cabbage adds much needed weight and contrast. This is the season of ripening fruit, so take advantage of the ever widening selection of Ornamental Peppers or consider shrubs with a nice berry set, such as Viburnum or Winterberry. Grasses add height and movement, and you can always use hardy grasses besides the more showy annual Pennisetum.
Second point: The growing season is slowing down here in the northeast, so start with larger plants and/or use more plants to fill up the container right away. There is not a lot of time now for plants to put on added growth. Think of assembling your container as you would a flower arrangement, except that this composition will last for weeks as opposed to just a few days.
Just the common name, Toad Lily, sparks curiosity and invites close inspection. The delicate blossoms of this attractive cultivar of Tricyrtis formosana resemble small orchids and have distinctive spotting on the blue-violet petals. Flowering interest begins in early August, but the golden yellow foliage adds color early in the season. Plants are stoloniferous, forming small clumps 12″ high, making it suitable for the front of a border. Small Hosta such as ‘Wogon Gold’ and Japanese Forest Grass Hakonachloa macra make excellent companions.
Grow Toad Lilies in a soil that stays uniformly moist, yet well drained. The foliage tips will brown if the soil becomes too dry, and although not lethal, will make the plants less attractive. Tricyrtis ‘Gates of Heaven’are unappetizing to deer, and are hardy through zone 5-9.
Not all Persicaria deserve persecution. Persicaria amplexicalis ‘Golden Arrow’ is not only one of the “good” members of the Polygonum (Knotweed) family, it is an extremely handsome and versatile perennial. The first thing you should note is the golden green lance shaped foliage, which is attractive all season. Big plus. In mid summer ‘Golden Arrow’ begins to display an array of ruby colored spiky tassels, which account for its common names: Firetail and Red Bistort. The flower show continues into September, and both flowers and foliage combine beautifully with the many late summer yellow composites, as well as pink or blue/violet asters, and of course all the Salvia.
Leaf color is brightest yellow when grown in full sun, but ‘Golden Arrow’ will require a little extra moisture if the area is on the dry side. Otherwise, grow it in a well drained soil in half day sun, where the golden yellow will tint slightly more green. Foliage height reaches 18-24″, with flowers adding another 6″ or so to the plant’s stature. The spread of each plant depends on age and culture, but expect Persicaria ‘Golden Arrow’ to eventually take up 2 sq. ft. It grows well in a wide range of hardiness zones from relatively mild zone 9 through a quite chilly zone 5.
Japanese Clethra is waiting to be discovered. It is a plant for all seasons, boasting fragrant mid summer blossoms, yellow-orange to red fall foliage, and exfoliating bark in winter. If left unpruned it will grow as a multistemmed shrub or small tree, but we prefer to see it trained to a single leader, with lower limbs removed, so that the showy bark can be better appreciated.
We were smitten when our young plant came into bloom in July. Trios of sweetly scented white, 4-6″, twisting racemes will drip from the branches into August. The ovate serrated foliage, in a shade of dark green, really sets off the white blossoms. Fall color is also striking, ranging form yellow orange to deep red. Although Clethra barbinervis is fast growing, it seems to reach an ultimate height of 15-20′. It prefers a well drained, neutral or slightly acidic soil with adequate moisture. Clethra barbinervis grows well in partial shade, although it will tolerate and bloom abundantly in full sun, if watering needs are met. It can be cultivated in zones 5-8.
We have fallen in love with the New England forest. It happened several decades ago, but it seems like only yesterday that the spell of fall was cast upon us. We know it’s the maples celebrating, in a festival of color, their happy home. A selection of Japanese Maple, Acer palmatum ‘Orange Dream’ begins this celebration in spring, with leaves emerging orange, unfurling to lemon-yellow with orange margins and finally settling in with yellow-green tones through the summer. Fall harkens ‘Orange Dream’ with a glorious display of yellow-gold. As winter peels off her leaves, the architectural intricacies of this small tree are revealed. Each season bring forth a new song from the branches of Acer palmatum ‘Orange Dream’.
‘Orange Dream’ appreciates an eastern exposure, where her feet will stay cool through the summer. She grows only a few inches a year, but will eventually find her way to 10′ x 10′. Site in a small garden or as an understory and you will fall in love too.
There is something especially striking about flowers which adorn bare branches before any signs of leaf growth appear. Hamamelis x ‘Feuerzauber’, a German hybrid selection of Withchazel (translation Fire Dragon), is hardy in zones 5-8 and boasts showy orange to red fragrant flowers in late February and March, which are as lovely cut for indoor arrangements as they are gracing the late winter landscape.
We recommend situating ‘Feuerzauber’ where you can enjoy its display from an indoor window. In fact, why not plant early blooming Crocus or yellow Narcissus ‘February Gold’ near its base for one of the first colorful ensembles of spring. ‘Feuerzauber’ will form a large shrub (15-18) with a pleasing upward spreading habit. It may not sing loudly in summer but it will celebrate Autumn with an amazing symphony of orange, yellow and red foliage.
