Quite different in flower colour and distribution, your's is from America.
If it's naturalised in your garden you are a very lucky person (or an expert
with them?).

The last remaining clump of truly wild ones was being guarded in a field
somewhere in Yorkshire I believe but has now set seed and the resultant seed
has been grown at Kew (The Sainsbury Collection?)

and some of the plants have been planted back in its native habitat.


Wasn't the Plantlife charity involved too?
