Bluebells are ideal for naturalising in grass or deciduous woodland. They can be vigorous, even invasive, but always put on a tremendous spring showing. The so called 'Spanish' bluebell cross-hybridizes with the 'English' bluebell, and being more vigorous will outcompete it. These hybrid bluebells are widespread throughout the UK, and the fear is: that as hybridisation becomes even more widespread, the gene pool of our pure, native bluebell will become increasingly diluted, eventually resulting in their complete loss. The 'English' bluebells are characterised as follows: Pollen: cream-white colour Flowers: Flowers are a narrow, straight-sided bell with parallel sides, and deep violet-blue. (But you may also occasionally find white or even pale pink flowers). The stems may droop or nod to one side, and the flowers have a strong, sweet scent. Whereas, with the the 'Spanish' and hybrid bluebells Pollen: Blue Flowers: Conical bell-shaped flowers with open tips, borne on upright stems, and have little or no scent
