King William Pine

Native to the mountains of Tasmania but surprisingly successful in the milder, high-rainfall areas of the UK like Cornwall and western Scotland, this primitive conifer offers a distinct, exotic appearance. It forms a slow-growing, conical tree with thick, overlapping, scale-like leaves that are glossy green with white stomatal bands on the underside. Historically, King William Pine was used for its light, durable timber, but in the UK, it is prized purely as a specimen plant for its textural foliage. It requires a cool, moist atmosphere and lime-free, moisture-retentive soil to thrive. While it can reach heights of 10-15 metres over many decades, it often remains a manageable shrub-like tree in garden settings. It is generally hardy down to -10°C, but young specimens may need protection from drying winds and late frosts. It is an excellent choice for a botanical collection or a woodland garden with a microclimate that mimics its temperate rainforest origins.
