This vine does not resemble the large flowering clematis that bloom in the late spring and early summer. Sweet autumn is a large vine, easily reaching 20-feet, usually more. The flowers are small, but there are hundreds. To me the real difference lies in the fragrance; sweet and strong it can fill the yard on a warm evening.
SAC is especially lovely n the twilight when each bloom shimmers like a tiny star amongst the dark leaves.
A great choice to soften the hard lines of buildings and fences. It creates an informal look perfect for cottage and country gardens. SAC requires no maintenance other than the occasional tuck or tie to keep stems contained and an early spring cut back. I have never seen disease or insect damage on this vine.
