Our garden is full of mature shrubs and trees but has very few flowers. We had lots of bulbs in spring but I really want to have a garden bursting with flowers. We have a couple of rose bushes and peonies but nothing else. I don't know what the shrubs are either so I may be pleasantly surprised. The garden is South West facing with clay soil. I think the soil is quite acidic as a camelia is growing very well. What would you plant to give some colour?
