Coprosma rugosa
Coprosma rugosa, also known as the needle-leaved mountain coprosma, is a shrub in the coffee family, Rubiaceae, that is native to New Zealand. It is found in grasslands and forest margins up to the subalpine zone. C. rugosa bears small purple-white berries in autumn, the seed of which is widely dispersed by birds. It is considered a very hardy shrub suitable for hedging.
'Clearwater Gold' is an excellent selection with golden young growth. Seen growing in the UK at The World Garden at Lullingstone Castle, Kent- it has proved reliably hardy even at -15° Celsius. Survived the Beast From The Eas,but winter 2022/23 knocked it right back to the ground.
