its a conifer.. and though i care not where you post.. there is a forum for such.. and there is a guru over there that can name ... precisely .. what it is ...

it reminds me more of an arb.. that i have as Thuja occidentalis 'Golden Globe' aka 'Globosa Aurea'

and one 'tell'.. is whether yours was ever sheared.. or if it is natural shape ... the one above.. grows in this shape.. all by its lonesome ... and you should be able to tell by sticking your head in it.. lol ...

coloration varies thru the year ... so i dont know if yours is the yellow version ... but you might want to change the search at the link to ... Thuja occidentalis 'Globosa'

good luck
