Sweet-Scented Seven-Son Flower: Heptacodium miconioides Blossoms Welcome Autumn . . .

September 23rd, 2018 § 5 comments § permalink

Heptacodium miconioides in and amongst September garden favorites: Rudbeckia, Solidago, Miscanthus and Physocarpus opulifolius

It’s no secret that we northeastern gardeners struggle with a limited growing season. Bare trees for nearly six months is a bit much to take. We want to hold onto the glory of autumn. Where winters are long and summers are short, early and late blooming plants —especially those with expanded foliage/bark interest, spring through fall— are key to getting the most out of the gardening year. When it comes to extending interest in the latter part of the gardening season, it’s hard to beat the beauty of Heptacodium miconioides. Commonly known as Seven-Son Flower, this unusual, low-maintenance shrub or small tree (hardy in USDA zones 5-8 with a preference for full sun and average, well-drained garden soil), is just beginning to turn on her charm in early September, when many other blooming trees and shrubs have long since faded away.

Seven-Son Flower (Heptacodium miconioides). September’s Sweet-Scented Bloom 

Fountain-shaped and substantial enough for the back or center of a large border (approximately 15-20′ high and 10′ wide), Seven-Son Flower may be grown as a multi-stem shrub or trained as a small tree. Shiny, medium green leaves cover branches throughout the growing year and then come late summer, Seven-Son Flower welcomes migrating Monarch butterflies. hummingbirds and bees with sweetly fragrant clusters of white flowers (each whorl containing seven blossoms).

But wait, as they say in late-night infomercials, there’s more! Although we gardeners would be more than happy with any shrub blooming this late in the growing season, the deliciously fragrant flowers are only half Heptacodium miconioides‘ surprise. After her blossoms fade, reddish purple fruit appears, surrounded by brilliant rose calyces. These spiky, sepal-like casings spread wide open, giving the appearance of a second flowering flush. I love the cherry red color against bone white tufts of feathery Maiden Grass. October surprise indeed! And just when you think the show is over, beautiful, two-tone exfoliating bark will take you by surprise as you stroll through the garden on the first frosty mornings of late fall and then continue on throughout the winter months.

Although this beauty can be a bit hard to find, she’s worth seeking out. I love her planted beside Physocarpus opulifolius ‘Diablo’ and Miscanthus sinensis purpurascens, supported by a cast of simple, late blooming perennials like Rudbeckia, Solidago, Aster and Chrysanthemum. Color and texture to extend garden beauty from late summer into autumn and early-mid winter. What a delight!

Butterflies on My Mind: Top Three Summer Blooming Plants for Attracting Fluttering Beauties to Your Garden…

March 11th, 2011 § 2 comments § permalink

Asclepias tubersosa (Butterflyweed) and Asclepias syriaca (Milkweed) are important sources of nectar for bees and butterflies. The leaves of Asclepias are also a source of food for monarch and other butterfly caterpillars.

With my seminar, “Gardening to Attract Birds, Bees and Butterflies” coming up on Monday night —and last week’s visit to Magic Wings Butterfly Conservancy still in my thoughts— you might say I have a fluttering of winged-creatures on my mind. Of course I’m always thinking of how to support honeybees in the garden (follow the Honeybee Conservancy blog here) and what’s good for the bees is often good for the birds and the butterflies. But when it comes to attracting monarchs, swallowtails, painted ladies and other kaleidoscopic, winged-beauties to your garden, there are three key “butterfly magnets” to consider in your planting plan. Butterflies enjoy many cluster-flowered plants, but Asclepias (Milkweed), Verbena —particularly Verbena bonariensis— and Buddleja species (Butterfly bush) are simply irresistible to them. Plant any one of these beauties in your garden and you will always get a landing and never just a fly-by. And as an added bonus, they are among the favorites of bees and hummingbirds as well…

Verbena bonariensis is a tropical plant grown as an annual or semi-annual (sometimes self-sowing) in cold climates. It’s popular with butterflies and bees alike.

Asclepias, more commonly known as milkweed, is a wonderful group of plants; including many natives. Last year I featured the gorgeous Asclepias tuberosa (Butterflyweed) in a post on mid-summer color (click here to read more about this North American native plant). I love bold color combinations in sunny, summertime perennial borders. Why not combine the sweet orange of butterfly weed with drifts of ethereal, lavender-hued Verbena bonariensis? Commonly known as purpletop vervain or tall verbena, Verbena bonariensis is a tropical plant native to Central and South America. In cold climates, Verbena bonariensis is usually grown as an annual or semi-annual plant (blooms the first year from seed and it will sometimes successfully self-sow), and in warmer climates it is grown as a tender perennial (hardy USDA zones 7-11). This is a tall, airy, elegant plant (approx 3-4.5′ tall and wide) with strong, slender stems (I like to grow plenty both in my perennial borders and in the potager for cutting). Purpletop vervain looks best when planted en masse for a hazy, purple cloud-like effect, and it prefers well-drained soil and plenty of moisture (will tolerate hot and dry, midsummer conditions once established).

Buddleja davidii (Orange-eye Butterfly Bush) lives up to its name. It is a favorite of butterflies, hummingbirds and bees.

Butterfly bush, or Buddleja (B. davidii pictured above) is perhaps the most popular plant for butterfly and hummingbird enthusiasts. Native to Chile and China, these flowering shrubs are long-standing, easy-to-grow garden favorites. Butterfly bush species are tolerant of poor, alkaline soil, polluted, urban situations and stress, making them a good choice in some areas. However, gardeners should be aware that one Buddleja species, Buddleja davidii, is listed as a “noxious weed” in certain areas of the United States (Oregon and Washington specifically list B. davidii as a noxious-weed, and it is possibly invasive in southwestern, coastal Canada) because of its free-seeding ways (it’s best to check with the USDA state noxious weed list online —linked here— or your local USDA Extension Service —linked here— before planting Buddleja davidii; particularly along the west coast and possibly in warmer states on the eastern seaboard)*. If you live in Oregon or Washington, or in another area where Buddleja davidii is considered invasive, consider a non-aggressive butterfly bush species, such as Buddleja globosa (USDA zone 7-11, orange ball tree/ball butterfly bush), or in cooler climates, consider planting native Clethra alnifolia (see my previous post & article on this shrub here). Buddleja davidii (synon. Buddleia davidii) is hardy in zones 5-9, and in cold climates (where it is far less likely to freely colonize and become weedy) B. davidii is treated as a perennial plant; cut back to the ground in late fall or early spring. New growth will emerge in spring and flowers will form on fast-growing young wood in the first year. Fountain butterflybush, Buddleja alternifolia, and Buddleja globosa (and other Buddleja species) produce blossoms on old wood, and should be pruned for shape in late spring or early summer after they have flowered. Buddleja alternifolia is considered to be a somewhat hardier species than Buddleia davidii. I have observed B. alternifolia growing in zone 4.

I will be writing more about how to attract butterflies, bees and birds to gardens in the coming months. But, if you are planning your garden now, you may want to add a couple of these sure-fire butterfly magnets to your shopping list!

*Buddleja davidii is not currently on the USDA federal invasive plant list. However, it is currently considered a “noxious weed” in Oregon and Washington (check state noxious weed/invasive plant lists here) Many plants considered “weedy” or “invasive” in one area are non-threatening in other areas. It is the responsibility of the individual gardener to know and respect the laws and environmental guidelines within their respective states and communities.
