I have very little knowledge about trees and flowers, but I quite liked this one at Brompton Cemetery. I obviously didn’t know what the tree was without assistance, but the cemetery had helpfully included a sign mentioning what it was.
The Latin name is Arbutus unedo and the fruit of this tree is apparently edible, although I didn’t try. Wikipedia notes that it’s often used in jams and I don’t disbelieve them on this occasion.
And the tree, quite a handsome addition to the cemetery.
