Leylandii ‘Castlewellan’ – A Golden Evergreen Hedge with Year-Round Colour & Screening

Leylandii ‘Castlewellan’ (Cupressocyparis leylandii ‘Castlewellan Gold’) is a vibrant, golden-leaved variety of the popular Leyland Cypress, perfect for creating a fast-growing, evergreen hedge with added colour and warmth. Its finely textured, soft golden-yellow foliage brings a bright, uplifting tone to the garden all year round, while its dense, bushy habit makes it ideal for privacy screens, windbreaks, and boundary hedges.

This vigorous, adaptable conifer grows quickly—up to 60–90cm per year—and responds well to regular trimming, forming a neat, uniform hedge that provides noise reduction, shelter, and privacy in a wide range of garden settings.

Why Grow Leylandii ‘Castlewellan’?

Bright Golden Foliage – Soft golden-yellow leaves add warmth and vibrancy, particularly striking in winter light.

Fast Growth Rate – Quickly forms a dense hedge, making it ideal for creating privacy or shelter in less time.

Year-Round Evergreen Coverage – Retains its colour and foliage all year for continuous screening and structural interest.

Versatile & Low-Maintenance – Suitable for formal clipped hedges, informal screens, or architectural shapes.

Planting & Care Guide

Position: Thrives in full sun to bring out the best golden colouring; tolerates partial shade but with greener tones.

Soil: Grows well in a wide range of soils, including clay, chalk, and sandy soils, provided they are well-drained. Avoid planting in waterlogged conditions.

Watering: Water thoroughly after planting and regularly during the first season to establish roots; drought-tolerant once established.

Maintenance & Pruning:

Pruning:
→ Trim 2–3 times per year between April and September to maintain size and encourage dense, bushy growth.
→ Avoid cutting back into old wood, as Leylandii does not regenerate from bare stems.

Feeding: Apply a balanced fertiliser in spring to promote healthy, vigorous growth and vibrant colour.

Perfect Uses & Combinations

Leylandii ‘Castlewellan’ is perfect for adding colour and brightness to boundary hedges, screening off unsightly views, or creating shelter from wind. Its golden foliage provides a stunning contrast against darker evergreens, making it a striking backdrop for flowering shrubs or perennial borders. Underplant with shade-tolerant groundcovers like ivy, hellebores, or ferns to soften the base and add textural interest.

Tip: For a formal look, keep regularly clipped; for a softer, natural hedge, prune lightly and less frequently to maintain golden highlights.
