This smells amazing, but I don’t know what it is.
Clematis Terniflora, or “Sweet Autumn Clematis”, it’s actually an invasive vine.
Clematis Virginiana, sometimes called “Virgin’s Bower” is a very similar plant, same nice fragrance, but with toothed leaves and is actually native to our area. I think I have some growing around here if you’re interested, because the terniflora should actually be removed, because it’s really aggressive
We sort of became pseudo experts at the whole invasive vine thing due to the amount of them we deal with on the property - Asiatic Bittersweet (displacing the native American Bittersweet and regularly strangling saplings to death), Japanese Honeysuckle (which sadly displaces the native and prettier Trumpet Honeysuckle and Canadian/American-Fly Honeysuckle - which is endangered now in our state), and Japanese Wineberry (which have delicious fruit, but are tenacious motherfuckers) are the really major ones I remember.
It was part of the Sculpture Garden, so I think it is here on purpose.
