This is the wild European bluebell. It is said that half of the entire global population of these bluebells is in Britain. There are fears that it will lose some of its characteristics if it hybridises too much with imported Spanish bluebells (Endymion hispanicus) which are quite different: lighter in colour, upright stems, more open, bell-like flowers rather than the cylindrical ones typical of E.non-scriptus, wider leaves. Spanish bluebells are usually what people have in their gardens. They are mostly blue, but also come in pink and white varieties.
