Julia - In the early 50's new neighbours arrived here from Aberdeen. I bumped into the youngest son (he must be close to retirement now!) in a local bank a few years ago, I was surprised as he had moved back to Scotland about 15 or more years ago. I was even more surprised that his wife lives in Scotland and he works as the only dentist on the Falklands. At the time I was interested in Empetrum rubrum (aka diddle-dee) and so he put the island botanist in touch. If you pm or email me I will track down his address.
By the way the reason for my interest in the Empetrum was a selection made by Barry Starling which he sent me in 1994, it was completely covered in white wool - var. tomentosum - and ever so choice with red berries. It's one you should have there in Scotland so you could send us a few cuttings

..........as I lost mine.
How's this for coincidence - Julia, you stayed directly across the street from the dentist's former house when you were in Hfx.
