Your garden is truly lovely. I tried to imagine your garden from a list but your pictures explained so much that was left out. Your shrubs and the terrace are also very much a part of the textured and add so much to your beds. From your pictures I'm guessing you also live in an old house. I really pack my plants close together too, so I understand what you mean by intensive planting. I'm looking forward to seeing the creation of your new garden bed.
