Cheseminer:  We've got chalky/sandy soil which is generally fatal to heathers.  In a raised section I've planted a few in some non-peat but acidic compost.  Only one or two have survived, and this one has done particularly well.
It's described as a "Hardy Heath" as opposed to a heather, and, although the planting instructions say 'incorporate moist peat', it also says "Suitable for all soil types".

Today, in a garden centre in the Peak District, I found Erica Arborea. This one is called 'Albert's Gold but I presume there will be others of a more mid green colouration. Like all ericas it prefers an acid or at least lime-free well draining soil. It can grow up to 34 inches in 5 years but is very tolerant of pruning and I think that in a soil slightly less to its taste it may be slower growing.
