Thanks again. I think that much of the bridewort I see - and there is quite a bit about - is probably a cultivated version / garden escapee.
They are all cultivated escapes or planted as none of the Spiraeas are native in the UK.
Oooops! Thank you again for clarifying things for me. So much to learn!!!
The learning never stops!
I know - but so little time!
