Judging by what i've read, the only thing i can think of is that being over a thousand feet above the south Wales valleys really suits these plants. We've had an extremely wet year prior to March and during March we had the first completely dry week since about May 2012. A few weeks ago Monty suggested selecting plants that are suitable for your local climate......maybe South Wales is similar to the Himalayas ! The one thats pictured is even in full sun all day, although again being high up just south of the brecon beacons we don't get a lot of sun.
