we have white bluebells in our garden, are these rare.
I had this ambition, to get rid of all the Spanish bluebells in my garden (planted by the previous owners) and replace them with English ones. I must say I gave up on that - the Spanish ones are very vigorous, and are growing and propagating so quickly, coming out on new spots all the time. It would take me years to get rid of them, so why bother. And I don't even want to try planting English bluebells, as they would just cross pollinate with Spanish ones.
Well, I comfort my self with the thought that the vigorous bluebells are good for spring insects as a food source.
