Climbers for supports either side of steps - clematis napaulensis?
I hope I'm not making a pest of myself by posting so many questions in such a short space of time, I promise I am actually doing a lot of research by myself before posting these questions!
Our rectangular garden is 5m wide by 20m. The long sides of the garden face north and south respectively. Halfway up the garden, in the middle, are a couple of steps up to the next level of the lawn. I thought it would be nice to plant climbers either side of the steps, supported by wire columns.
I spotted a variety of clematis called napaulensis. I think it's so pretty and love the fact that it flowers in winter. I thought (hoped) it might be successfully combined with another deciduous, summer/spring flowering climber.
Given the dimensions of the garden and positions of the steps, is this at all realistic? I'm unsure as to whether this spot counts as 'exposed' - although it's in the middle of the garden and not sheltered by a fence, the fences are only two metres away from either side of the steps.Before I came across the napaulensis, I was thinking of something evergreen and flowering, but I'm quite happy to combine two different plants in order to get year-round foliage and perhaps even year-round flowers.Thank you in advance.
