The appearance of Asian jasmine climbing red bricks is pleasant and romantic.
On the other hand, it's invasive, non-native, and unduly exerting its influence over the arboretum. Begone!
Here the heavy, awkward sheets of jasmine have been pulled off the wall and piled up at the base. They (five-to-ten interwoven vines per foot of wall!) still have to be sliced & diced to separate them from the root networks.
Now the architectural appeal of the brick retaining wall is able to be appreciated more effectively. The vines were nice, but this is also good. And don't worry; the jasmine will be back to making its vertical advance after a year or two of regrouping.
