While this plant is invasive in warmer climates, it is invaluable to us in Zone 3 where it is very hardy. There are not too many vines that can be grown in cold climates and Sweet Autumn Clematis is tough enough to survive our -40 C winter temperatures.
Easy care beautiful vine for quickly covering an old fence or arbor. The flowers that appear at the end of the summer are a welcome sight when the blooms on most other plants are gone. The fact that it tolerates shade is an added bonus.
I'm in zone 5 in Michigan. This was planted in a mostly shady area, heavy clay soil. I didn't really expect it to grow, but it performed beautifully. Was very vigorous--I cut it to the ground each spring without problems. I guess it could be invasive in other climates, but it wasn't really a problem--you can simply cut off the parts you don't want. A really great plant for the late summer garden when other plants are starting to look a little tired.
I have over 30 clematis and this is by far my favorite. Butterflies and bees love this plant and the fragrance is to die for. It grows outward from the ground to quickly fill in a fence where most other clematis grow straight up. You can grow this on a fence or over a stump or structure such as a garage or shed. This clematis is a pruning code 3 and I cut mine down every spring. This clematis takes no special care, dig a hole and throw it in and forget about it. No need to be gentle with this clematis, it is the most hardy clematis I have. I never have had a problem with self seeding. I highly recommend this plant. Don't be afraid of the size, just take it into consideration. I live in town and have 3 Sweet autum clematis.
Do not plant this vine. The previous owners planted this on the side yard and it has killed the trees, it spreads through out my yard. I have spent the past 6 years pulling this out of the trees and yard.
I give this plant a rating of ZERO. In order to get this to post, I had to click on a leaf. In my home town, Manteo, NC, on the Outer Banks, this has become a noxious weed. It covers everything worse than Japanese honeysuckle, blocking the light and killing many fine, expensive shrubs. I spend much of my 'vacation' time trying to eradicate this beautiful, Kudzu-like criminal. PLEASE STOP RECOMMENDING IT!!
