| Positive | On Jun 16, 2008, philomel from Castelnau RB Pyrenées, This lovely clematis doesn't hold on to anything, but leans on its neighbours for support. I find it very lovely leaning into Elaeagnus x ebbingei 'Limelight', whose soft yellow leaves complement the indigo flowers of the clematis. |
