Hold on a minute.
I live in Scotland UK where Heathers cover the hillsides.
I find them tricky to id.
This one was found in Cornwall...so may not be Erica cinerea ...common name bell heather,
I wonder if it is Erica vagans...common name Cornish heather????
But do not have sufficient expertise. Sorry.
Others can decide.
