What plants are shading your Clematis Roots?
I would love to know what plants you have planted in front of your clematis. I have most of mine growing on trellis on a North facing fence, in a four foot deep garden bed. They all get afternoon shade. I absolutely cannot grow Hosta here. I had day-lilies in front of them, but they over crowed the clematis. What is a good size plant to put in front of them? Thanks for any suggestions.
