I'm sorry, but if I were you I'd move it - it is growing right on the boundary line and flopping over their garden. They'd be within their rights to cut it back to the boundary line.
They obviously have different tastes to you - they like clear lines and clean gravel. Presumably they don't impose their taste on you and if I were you I'd avoid appearing to try to impose my taste on my neighbours' garden.
Good neighbourly relations are worth a mint!
