It was all I could do to not put a ? in the subject line. My friends have five of these young trees in a bed in their their garden but they didn't know the name. It fits the description and the photos I see for Chamaecyparis obtusa 'Fernspray Gold'. The brightest yellow one was facing south; the others were in the same bed but were more shaded. The second and third leaf photos show one branchlet turned over to reveal the green underside.
