Evolution Plants near Bradford on Avon is holding a special open day on the 10th of May when the public can visit the nursery for the first time, buy plants and go to nearby Belcombe Court to listen to a talk by American plantsman extraordinaire, Dan Hinkley. The 50 acre garden of Belcombe Court features a huge walled garden designed by Arne Maynard and is rarely open to the public. The talk is ticket only (£5) redeemable against plants bought on the day. www.evolution-plants.com
