Suttons have a lovely history page on their website. Apparently they are now part of the Vilmorin group. I looked up Vilmorin on the Web and found both Dobies and Suttons listed as subsideries under the name Suttons, so yes they're one and both the same. The fact that they're both based in Paignton's bit of a giveaway too. It's a real shame when these old established companies get taken over but why continue to trade under their different names? Incidentally, Ferndale Lodge is also a Vilmorin subsidery.
