Native species of bulebellby Malcolm Greenhalgh on 07/03/13
Introduced species of bluebell are threatening our native ones (species Hyacinthoides non -scripta) by interbreeding with them. Our native ones are far more interesting and stricking than the non native.; if you want to rid your garden of the latter then here's how to tell the difference.
In our native bluebell the pollen is white (blue or bluegreen on non native), the flower is "nodding" and most flowers come from one side of the stem (more erect and flowers from all around the stem), and the flowers have lovely perfume (the foreigners and hybrids have little if any perfume).
I have zapped one patch on non native with Glyphosate.
