England is home to 50% of the worlds bluebell population of Hyacinth non-scripta. They are protected and its a £5000 fine to either dig them up or sell either the bulbs or seed. Theres one licensed seller of native seed in Wales, and another in England.
Those of us who are fortunate enough to own a bluebell wood should familiarise themselves with the legislation, and do their best to protect and nurture this spectacular native English plant.
I easily found several sellers of native English bluebells on Ebay, and have just sent them all a reminder of the law on selling them. They may have come from a licensed source, but you know what Ebays like... Awaiting replies.
I've found if you have a large area of brambles fringed by bluebells and clear the brambles, the bluebells rapidly recolonise the area. A nice simple way of doing your own bit to protect an endangered species and make your wood more accesible at the same time...
Interesting Bluebell Survey here, charting distribution and explaining the legislation too;
