Jamis this is the plant that we have always grown as Limonium bellidifolium, but I did look at the web too and there are some narrow leaved forms there, as well as the form we know of as L. bellidifolium. Limonium bellidifolium grows wild in the sandy fore shore at Robe in S.A. have you seen it there?
According to the AGS Encyclopaedia of Alpines there is a quote "12cm long leaved form from the Ukraine, L.danubiale. It seems likely that true L. bellidifolium is seldom cultivated, other species being offered in its place." unquote. May be some one from UK or Europe will recognise it. Viv
