Just an idea, but what about contacting your local Wildlife Trust
It being Cornwall, with a milder climate than most of the UK, there may be something that's made itself at home there which doesn't grow as well if at all in the rest of the country.
P.S. Very envious of your cottage in Cornwall, even with rampant unknown plants ... we'll be down your way later in the year as usual
