Will Puschkinia Libanotica cross with English Bluebells
I have recently been given some lovely striped squill, Puschkinia Libanotica. But having spent 2 years removing Spanish Bluebells from my garden before planting English Bluebells I am now concerned if these Puschkinia Libanotica will pose the same threat of cross pollination. Where could I get a definitive answer to this problem? I don't want to undo all my hard work removing one threat only to replant another.
