About Your New Cupressus macrocarpa 'Goldcrest' (Castlewellan Gold)
Thuja occidentalis 'Castlewellan Gold', commonly known as Castlewellan Gold, is a fast-growing conifer celebrated for its vibrant golden-yellow foliage that brightens gardens all year round. Its upright, conical form makes it a versatile choice for hedging, screening, or as a striking standalone specimen.
Reaching a mature height of 3–4 meters and spreading 1.5–2 meters wide, Castlewellan Gold thrives in full sun to partial shade and tolerates frost and urban pollution, making it well-suited to a variety of environments. With moderate drought tolerance and low maintenance needs, this evergreen conifer requires only occasional pruning when shaped as a hedge and regular watering during dry periods.
Castlewellan Gold looks excellent when you want to add a splash of color and structure to your landscape—whether in a neat hedge or as a vibrant focal point that stands out in any garden setting.
