Thanks Verdun and everyone else too - whilst I'm not a fan of the chopped-within-an-inch-of-its-life look, I will prune back hard if someone more expert than me tells me it does the plant the world of good. That said, I have ;eft said potentilla alone one year and it still barely flowered...then chopped it a lot the year before and it barely flowered., so I'm at a loss to understand what suits it best.
Maybe at 3 years old it should just be left in peace to do it's own thing, with minimal interferences from me, and only if necessary to remove any dead bits!
Re thyme - I am waiting 'til spring. It can't come soon enough for me
