Product Details

Product Details

A gorgeous sight when covered in pure white, lightly fragrant flowers in late summer, Sweet Autumn Clematis becomes a silvery mass of fluffy seed heads in the fall. We're particularly fond of the established plant that grows on an old stone wellhead at the nursery (shown in photo) that's over 10 years old. But this prolific, small-flowered species will look equally impressive covering an upscale arbor or embellishing a utilitarian fence or garden shed. Pruning group 3.

This hardy climber is a rampant grower that can reach to 30′, but can easily be kept in check by cutting stems back to 12″ in spring. It blooms on the current year's growth, and unlike many Clematis, it will thrive and bloom well in partial shade. Plants are unlikely to bloom the first year, but expect them to begin blooming the second year. Please note: Sweet Autumn Clematis can grow quite vigorously to the point of being invasive in warmer areas of the country.

HOW PLANTS ARE SHIPPED

The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.

WHEN WE SHIP

We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. Estimated dates for shipping are indicated in the Shipping Details box for each item. Please refer to the Shipping Details box to determine the earliest shipping time. Unless you specify otherwise, fertilizers, tools, and other non-plant items are shipped with your plants or bulbs. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at expected time of delivery.

OUR GUARANTEE

We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it. Please contact our Customer Service Department at 1-800-503-9624 or email us at [email protected]. Please include your order number or customer number when contacting us.

Will be buying a 2nd

A viewer from NE

My first SAC is, what, maybe 4 years old. I did have it climbing onto a too short trellis. This spring I moved my cat's "catio" so that the east side of the catio (10' wide x 6' tall) became the trellis. Trimmed last years spent growth early this spring and this thing is growing like crazy! But i will need a 2nd SAC to fully cover the 10' width. Perfect shade for my Hazel. Will order for fall planting!

Extremely Invasive Plant

Rosemary McGarrah from Southern Indiana

This plant does grow quickly and looks beautiful, but in the southern end of zone 6 and warmer, it is highly invasive. From personal experience, if you plant it, it will take over and the seeds will spread. Apparently further north the cold is enough to stop reseeding. Don't touch this plant if you are in the Lower Midwest or South.

GORGEOUS and easy - and bees love it!

A viewer from Sierra foothills in northern California

In its first season, our Clematis paniculata from White Flower Farms is a beautiful, hearty success!!! I resisted a 5-gal specimen from a local nursery last year because it would be too hard to make a really good, big hole for it in our clay-based soil. Instead, I ordered the much smaller plant from WFF in far-away CT. I was able to make a super-duper hole for the by-contrast wee thing and put a small tomato cage over it to protect and mark it. It took off growing lovely foliage this past spring and summer and needed no special attention (other than tying it in a couple places with string to our porch post where it continued traveling up to the top of our pergola and also beautifully cascaded down over the string - making an easy, flowing arrangement of itself). Now during its first autumn, it is in amazing full bloom with cascading clouds of white flowers surrounding our porch post and mounds of flowers on top our pergola that make a gorgeous scene from our second-floor windows. I like that the bees love it, too (but are not bothersome even though very near our front door). I'm so impressed with the quality of WFF stock and with their service (including peonies from them that also are in their first season). Now that I see the wonderful results, I'm ordering two more Sweet Autumn Climatis (one for a another front porch post and one for our garden gate arbor). BTW in case useful: our current Clematis gets morning sun and is shaded in the afternoon (until it approaches the top of the pergola).

Sweet Auumn Clematis

Joan Richards from northern VA

This is a lovely clematis, fragrant and showy BUT it is terribly invasive. After two years of beautiful blooms in 2009, I found it all over my herb garden and surrounding gardens. I removed it but continue to fight the battle to remove t. Just this week I found it growing up a black tupelo tree, a good 50 feet from the herb garden. Seems impossible that I am still fighting this vine 7 years later.

Latin Name Pronunciation: klem'uh-tis

This very diverse group of lovely, ornamental vines will entice you to garden on the vertical plane. There's a Clematis for virtually every situation: grow the shorter and non-climbing types through shrub Roses and small trees and cover an arbor or a trellis with the taller varieties. The long flowering season begins with the compact alpinas and macropetalas in early spring, progresses through early summer with the large-flowered hybrids, continues through late summer with the boisterous texensis and viticella varieties, and concludes with the exuberant and infallible Clematis paniculata that will literally cover an unsightly structure or arbor in one season.

Light/Watering:

  • In general, these lush vines like at least 6 hours of sun. Some varieties are adapted to partial shade and all benefit from afternoon shade in the South.
  • Clematis prefers a cool root run, so lay flat stones at its base, or plant annuals or shallow-rooted perennials around them.
  • Regular watering is desirable, especially during seasonal dry periods. Clematis is deep-rooted, so water thoroughly.

Fertilizer/Soil and pH:

  • Clematis is at its best in rich soils with good drainage. It prefers a neutral soil, so check pH and add lime if needed.
  • Dig a generous hole and amend soil as conditions indicate, avoiding fresh manures.
  • Plant the crown of your plant 3–4″ below the soil surface; this will protect dormant buds that will provide new growth if the existing stem(s) are injured.
  • Provide support immediately or plants will languish.
  • Clematis is a heavy feeder; supply a low nitrogen fertilizer such as 5-10-10 in spring, when the buds are about 2″ long. Alternate feedings every 4 to 6 weeks with a balanced 10-10-10 fertilizer. Continue this alternate feeding until the end of the growing season.

Pests/Diseases:

  • Clematis is susceptible to fungi that can cause the vine to suddenly wilt and turn brown or black. Carefully prune out all diseased tissue and destroy; disinfect your pruners with a bleach solution. Generally this disease is not fatal, especially if you have planted the vine correctly, as dormant buds will send up new growth from the crown.
  • Handle gently when planting and be careful when cultivating, as physical injury to the stems can cause them to wilt and die.

Companions:

  • Plant these lovely vines at the base of shrubs and small trees; they will weave their way through the supporting foliage and extend the season of interest with their showy blooms.
  • Use the woody structure of Shrub Roses to support the non-clinging Clematis varieties; for instance, grow purple or blue Clematis through a yellow Shrub Rose for a fabulous contrast. Remember that a supporting woody plant will compete with the Clematis for water and nutrients and adjust your culture as necessary.

Reflowering:

  • To promote reflowering for late season bloomers during the growing season, the vine can be cut by one-half after the main bloom period.
  • Varieties that flower on old and new wood will often throw out a few blooms at the end of the growing season.

Transplanting:

  • Young vines may be moved with plenty of soil as long as they are watered religiously.
  • Depending on variety, cut back lightly or severely before moving in early spring.

Pruning:

  • Dead or damaged stems may be removed at any time.
  • Early in the first spring after planting, prune the stems of all Clematis varieties down to the lowest pair of healthy buds. Thereafter, prune to control size and shape or to encourage more profuse bloom.
  • Flowering tends to decline on stems that are four or more years old, so it's a good idea to prune out very old stems periodically in early spring. This pruning helps produce more compact plants with flowers closer to eye level. Sometimes, on older vines, the flowering is confined to a small area at the tops of the stems.
  • If you wish, you can rejuvenate old plants by cutting them back severely, to about 18". Wait until after the first flush of bloom to perform the surgery.

Clematis are divided into pruning groups as follows:

Group I plants bloom on old wood and require no pruning except to control size, in which case prune lightly after flowering back to a pair of healthy buds. Group I varieties include Clematis alpina 'Stolwijk Gold' and Clematis montana 'Mayleen.'

Group II plants bloom first on old wood and then again on new; prune lightly in early spring to shape and remove weak growth and then prune after bloom if desired.

End of Season Care:

  • Plants may be mulched, but take care to keep mulch material away from the crowns and stems of the plants.
  • Check to make sure that the vines of Group I and II plants are tied securely to supports to withstand winter winds.

Calendar of Care

Early Spring:

  • Fertilize with 5-10-10 when new growth reaches two inches.
  • If you need to move a plant, transplant young vines now.
  • Wait until new growth appears before removing dead or damaged stems and before pruning as required by variety: leave Group I Clematis alone; prune Group II plants lightly to shape and remove weak growth; cut Group III varieties back to 12 inches above the ground, or higher if you desire taller vines.
  • If this is the first spring after planting, prune stems of all varieties down to the lowest pair of healthy buds to encourage strong growth and new stems.

Mid-Spring:

  • Continue feeding every month, alternating 5-10-10 with 10-10-10.
  • Plant annuals at base of plants if unprotected by flat stones to allow for a cool root zone.
  • Gently tie vines to supports as they grow.

Late Spring:

  • Mulch if desired but keep material away from crowns and stems.
  • Water thoroughly if season is dry.
  • Cultivate around vines with care as physical injury will cause wilting and death of injured stems.
  • Continue to guide new growth by tying to supports as needed.
  • Lightly prune Group I Clematis immediately after flowering to shape the vines if needed.

Summer:

  • Watch for signs of fungal wilt and remove and destroy affected plant parts if it occurs, then sterilize pruners with bleach solution.
  • Group II Clematis may be pruned back by one-half after main flush of bloom to encourage strong growth and new flowers.
  • Continue to water if conditions indicate.

Fall:

  • Check to be certain that the vines of Group I and II varieties are tied securely to supports to withstand winter wind and snow.
  • Mulch if desired, keeping material away from the crown.
  • If the season is dry, water well and deeply.
