Clematis are among the most decorative and spectacular of all the flowering vines, and mine are blooming so beautifully this season.
I have always loved clematis, and over the years I have grown many varieties of this wonderful plant. When I purchased my Bedford, New York farm, I knew I wanted to build a long, winding pergola where I could grow lots of clematis. After the pergola was constructed, I concentrated on creating a palette of blue-flowering cultivars and each year I always enjoy the vivid floral display.
Enjoy these photos.
There are several different varieties of clematis planted along my winding pergola that extends from the carriage road in front of my flower cutting garden all the way to the west end of my soccer field. Each pair of posts supports the same variety and every year around this time, they stand out under in all their gorgeous colors.
Wire is wrapped around each post, so the climbing tendrils of the clematis vines could attach easily. The uprights for this pergola are antique granite posts from China originally used as grape supports. They’re perfect as posts because they don’t rot over time like wood does. A friend of mine acquired a lot of stone from this valley and I purchased a couple hundred of these posts. I only wish I had bought more of them.
Clematis is a genus of about 300-species within the buttercup family Ranunculaceae. The name Clematis comes from the Greek word “klematis,” meaning vine.
Clematis leaves grow in pairs along the stems. The clematis leaf shapes vary with different varieties, but knowing how they grow can help differentiate them from other vines.
Clematis are native to China and Japan and are known to be vigorous, woody climbers.
Most species are called clematis, but it has also been called traveller’s joy, virgin’s bower, leather flower, or vase vine. It’s also been called “Old Man’s Beard,” because of the long fluffy seed heads that look similar to an old man’s beard.
The standard clematis flower has six or seven petals, measuring five to six inches across. Colors range from lavender to deep purple, white to wine red, and even a few in yellow.
For this area, I chose various shades of lavender, purple, and blue.
Some of the flowers are very light colored – almost white – with interesting centers.
Many clematis are lightly scented. Flowers vary in shape and sizes. They can be flat, tubular or bell-shaped and can be as small as one-inch wide.
Some clematis cultivars will bloom in partial shade, but to really thrive, they need at least six-hours of sun each day. Just think, “head in the sun, feet in the shade.” The vines like sun, but cool, moist soil.
Once established, clematis should be watered about an inch or so weekly, and more deeply during dry spells.
Some of the cultivars grown here include ‘Parisienne,’ ‘Blue Angel,’ ‘Jackmanii,’ and ‘Eyers Gift.’
It can take several years for a clematis vine to mature and begin flowering prolifically. To shorten the wait, purchase a plant that’s at least two-years old. Clematis also prefer soil that’s neutral to slightly alkaline in pH.
This is Clematis viticella ‘Betty Corning’, which has slightly fragrant, bell-shaped flowers that bloom from summer to fall.
Here is a similar variety in pinkish purple.
Across the carriage road from my pergola, I also have some clematis vines planted at the base of several bald cypress trees. On these trees, we used twine to secure the climbing vines.
The timing and location of clematis flowers varies – spring blooming clematis flower on side shoots of the old season’s stems. Summer and fall blooming vines flower on the ends of only new stems.
Here is lavender bloom with a large, showy center.
Here’s one in dark purple.
Clematis plants are also heavy feeders and benefit from a low nitrogen fertilizer such as 5-10-10 in spring, when the buds are about two-inches long. Alternate feedings every four to six weeks with a balanced 10-10-10 fertilizer and then continue this alternate feeding until the end of the growing season. The blooms appear constantly for many weeks making their everblooming nature a must-have in any garden.
As a perennial, clematis are vigorous vines that return yearly and are hardy in USDA zones 3 to 9. My farm is in zone 6b.
Both butterflies and hummingbirds are attracted to clematis flowers.
Known as the “Queen of the Climbers”, Clematis plants will train onto posts, trellises, and fences, or arch gracefully over doorways. What are your favorite clematis varieties? If you don’t already have clematis in your garden, I hope this inspires you plant one, or two, or three…
