My favorite source: Van Engelen Bulbs. They have your bluebells listed under Scilla (hyacinthoides and scilla are interchangeable). Sales don't reopen until the middle of May but prices are wholesale and you can fill up a dale for a wee penny. I have many of them in my garden and love them dearly. Good luck.

Here is a link that might be useful: Van Engelen Bulbs

I would also like to get my hands on some traditional bluebells. Does anyone know of a source in British Columbia?

Will check out Van Engelen and Vesey's...have also found a place in Campbell River (on the web)

which looks promising. If anyone else has any ideas please let me know.
