Product Details

Product Details

A gorgeous sight when covered in pure white, lightly fragrant flowers in late summer, Sweet Autumn Clematis (Clematis paniculata) 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.

Shipping

Shipping
Every state has agricultural regulations that restrict the shipment of certain plants. We're sorry, but we cannot ship this item to the following states: New York.

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. We also ship a wide range of containers and planters, tools, supplies, fertilizers, garden wear, garden decor items, as well as indoor decorations like wreaths and dried bouquets when available. Estimated dates for shipping are indicated in the green Shipping Details box for each item. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at the expected time of delivery.

Recommend spring planting in Massachusetts

I purchased two of these, one in the spring of 2020, one in the fall. The spring-planted did well and grew over a covered bench, although it did not flower the first year, which I was expecting. The fall-planted one did not make it through winter - and sadly I will need to wait a full year until next spring to be able to plant a replacement (no longer taking my chance on a fall planting in my zone). I am hoping the one survivor will flower this year!

Sweet Autumn Clematis

I just planted the 2 Sweet Autumn Clematis I received from WFF. They arrived very healthy, with approx 12" of growth. Being in the northeast I really don't have to be concerned with this plant becoming invasive. I had these same Clematis in my last home. After approx 3 years they began to fill in and grow more. I am holding the same hope for these. I have a lovely tower for them to grow on. I have been very fortunate with my past experience with WFF. Leaving our garden when we moved was difficult, as it was well established.

So happy!

This is growing beautifully in it's second year, and it's exciting to train new tendrils on the wires each day against an ugly retaining wall backdrop The flowers are lovely and delicate and blooming in full clouds of coverage.

Pleased...but...

We planted a start from a mature plant several years old. It grew immediately in the 10 inch part and eventually grew 2 feet and slightly bushy. It did not bloom the first year. The second year it looked like it was dying, and because we didn’t know anything about propagating it, we thought it was lost. Eventually new growth came out and we placed it out in the yard in fuller sunlight. It barely bloomed the second year and the third year. It never grew longer than 3 spindly feet tall. In the fourth year we placed the pot out in the backyard with some of our other potted plants, and it still was not happy. So I cut the bottom out of the decorative pot to allow the roots to expand. Within a few months the plant was growing extremely fast and bushy to the point of 4-5 feet, and in the late spring bloomed beautifully. It has bloomed since then two or three times a year. The only disappointment I have is it has not spread nor become invasive. No seedlings or runners have ever appeared. We only wish it would be more aggressive so that our drab looking area here in this part of Florida could be dressed with cascading white flowers. We tried unsuccessfully rooting its cuttings. We hope to buy it here sometime soon to create a massive cascade.

Perfect for cold zones

Sweet autumn clematis is not particularly invasive if you live in Zone 5 or further north. Winters are just too cold for most seedlings, and you can pull whatever takes root easily enough. That being said, this plant grows like gangbusters when you stick it in the ground. I got a small sprout this spring to cover up a bit of unsightly area underneath a new deck. It's a south-facing area that gets a lot of sun. That little guy wasted no time in stretching for the upper deck railings and is now about 10 feet tall. No expectations that she will bloom this year, but I wouldn't be shocked if she did, either. Great and useful plant for quick cover of structures.

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 mulch 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,' Clematis montana 'Mayleen,' and Clematis Sparky® Blue.

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.
