We read a lot about invasive animals but as I've indicated before we are as much at risk of flowers introduced by Gardeners.
Managers at the National Trust’s Mottisfont Estate say the invasive Spanish Bluebell has spread from private gardens into the wild. They have become established in woodland and are posing a threat to native bluebells.
Apparently Britain has more than half the global population of the native bluebell, however loss of habitat, climate chance and the continuing spread of the Spanish bluebell is but our native Bluebell under severe threat.
The native bluebell is distinguishable from the Spanish Bluebell by its strong sweet scent and intense violet-blue colour. Flowers drop down like a bell along one side of the stem.
The Spanish variety is a pale blue, has larger more upright flowers and little or no scent.
