Just back from the Bakewell Secret Gardens afternoon and am still thinking about one garden in the town centre.
The whole space was only about 20 feet square and had 7 foot high limestone walls all round. On the south-facing wall was a hydrangea aspera Villosa and running through it was a clematis viticella Mary Rose and a clematis flammula.
That, essentially, was the entire garden. The effect was stunningly pretty. And for anyone who wants a large shrub with lilac/mauve flowers that are covered in bees, you could hardly do better. The clematis flammula lent a wonderful perfume, which was held in by the high walls.
Sorry, I'm starting to sound like Carol Klein.
