See this post from ten years ago for an explanation of how the garden has been developing over the 20 years since we began it.
That underlying plan is becoming the dominant one and has a quite different character from the flower garden I began with. There are still flowers - I couldn't be without them - but form has become more important I would say and I am thrilled with the composition of horizontals and verticals and the contrast of wild and clipped.
The three cornus controversa variegata, also known as the wedding cake tree have done well. They grow very slowly, and the tallest of them (I can now wallk under it!) loses a lower branch every now and then, so I have bought another to plant at its base in the hope that they will eventually combine their horizontal tiers to make a beautiful centrepice.
