Growing clematis *down*? And other questions
Our backyard has a large sloped area that has been covered with granite for drainage/erosion prevention purposes. The rock is lovely but needs some foliage. Clematis was suggested.
There is suitable planting space both above and below the slope. Should I plant at the top and train the clematis down? Should I plant both top and bottom?
Also, how many varieties should I plant? I assume (I'm totally new to gardening entirely) I should focus on flowering time so that I have something flowering in spring, midsummer, and late summer too. The area is almost 50 feet wide and 8 or 10 feet tall, so I have a lot of space to work with. Should I go crazy and plant a different variety for each planting? Or should I be more conservative and select maybe 3 varieties and space them out accordingly?
