Splendid tree in small sheltered garden near the coast but surrounded by farmland.
No interactions present.
This is a lovely old specimen. They prefer these sheltered sites in full sun. I have seen huge numbers of Red Admirals on them when they are flowering.
Well spotted David, at first glance this does look like Arbutus, but if you look more closely, these fruits have a sort of "Eden project" geodesic look to them, whereas the second-year fruits of Arbutus ("Strawberry Tree") have little spikes all over them.
Also, the dogwood generally (not always) holds them singly, whereas Arbutus has the fruits in small hanging bunches. Not a terribly good ID point, but every little helps.
