Real or fake?

These pretty Bluebells growing in my garden are the fake Spanish bluebell Hyacinthiodes hispanica a rather naughty impostor which is a real danger to our beautiful native bluebell Hyacinthiodes non-scripta. Not only is it more vigorous than our native, but also readily hybridizes with it destroying native bluebell stock.
It can be distinguished from the native by the much larger strap-like leaves, and the wide open bells that are arranged around the upright stem and not just on one side. Spanish bluebell pollen is also blue where that of our native is white.
These are from my garden, not planted by me, but I do feel I may need to dig them up and destroy them very soon.
