Great! It's called Lysimachia atropurpurea 'Beaujolais' and it's on the Sarah Raven website.
Good news! It's in stock. It should be £5.50 plus £4.95 postage but I've found a voucher code and it gives 10% plus free postage so it's coming in at less than £5! Brilliant!
Type in the box that says 'Have an offer code' this: SAVSP16
I've bought one just now. Perhaps if anyone that wants to join in buys it this week too we can compare how we get on! Love it! Our own little trial!
