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".
