I’ve zoomed in as much as I can and the tall round “trees” here appear to be boxwood. Could be holly. Anyone possibly able to answer? I’d think they would have to be pretty old (and pricey) to be at that height. Very appealing.
These are not box, these are Ligustrum (privet), but there are lots of plants that can be bought as lollipops (standards).
