We are planting an emerald cedar hedge. The cedars are approx 8 ft tall, and I would like to grow a clematis on them for some colour. Any suggestions for a pref group 1 clematis i.e. little if any pruning, colour preference would be white, pink or red. Does anyone know if there is a really small flowering red one? A trouble free plant would be preferred. East facing location, fairly windy. Thanks in anticipation!!
