Mika, I had read that somewhere about Winchester Cathedral and I saw a mention somewhere that it may eventually be phased out of production. I've also read a lot of positive reviews of gardeners growing WC which was a little puzzling.
Lyn, have you noticed that David Austin recommends planting roses 18" apart? I was surprised at that. He also recommends planting 3 of a variety to achieve the look of a large shrub, but I always figured that's just an attempt to sell more roses. I try to avoid having roses too close together, but do crowd companion plants around them. I prefer companion plants that either deter pests or aren't bothered by them, but as long as they don't draw anything that likes roses I'll use them nearby.
