Golden Leylandii hedge plants – Castlewellan Gold
Golden Leylandii, x Cupressocyparis leylandii 'Castlewellan Gold', combines the vigorous evergreen growth associated with Leylandii with bright golden-yellow foliage. The colour gives it a very different appearance from traditional Green Leylandii, while still producing the dense structure needed for privacy screening, boundary hedges and formal clipped hedging.
Its foliage can take on warmer bronze tones during the colder months, adding seasonal colour while remaining evergreen. Our Golden Leylandii is supplied pot grown in a selection of starting heights so you can choose the size that best suits the length of your hedge, the level of immediate screening required and your planting budget.
Gwynne's Grower's Tip
Golden Leylandii responds best when you start managing it while the plants are still young. Decide roughly how wide and tall you want the finished hedge to be, then trim little and often as it develops. That keeps the foliage dense and avoids having to make severe cuts into older bare wood later.
Choosing the right hedge
Is Golden Leylandii right for your hedge?
A great choice if you want:
- Fast evergreen screening with brighter foliage
- Privacy hedges where golden-yellow colour is preferred
- Formal hedges that will be clipped regularly
- Exposed or coastal positions
- Pot-grown planting where a flexible planting season is useful
Consider another hedge if:
- Very narrow borders with little room for future trimming
- A hedge you want to leave completely unmanaged
- Persistently waterlogged ground
- Positions where future access for pruning will be difficult
- Gardens where a slower-growing hedge would be easier to maintain
Why choose Golden Leylandii 'Castlewellan Gold'?
Golden Leylandii is a good choice when you want the speed and dense evergreen structure of Leylandii but prefer a brighter hedge. Its golden-yellow foliage gives boundaries and screening a much lighter appearance than the deep green of standard Leylandii.
It is particularly useful where fast establishment, year-round screening and strong foliage colour are all important. Regular clipping keeps the hedge dense and controlled and allows it to be maintained as a formal screen rather than developing into a large free-growing conifer.
Choosing the right Golden Leylandii size
Smaller Golden Leylandii plants are usually the most economical option for longer hedge runs and are straightforward to handle and plant. Larger plants provide more immediate height and visual impact where faster initial screening is the priority.
Planting density should be based on the exact size you choose. Use the live plants-per-metre recommendation shown with each available size above rather than using one spacing figure for every Golden Leylandii plant.
Maintaining a Golden Leylandii hedge
Golden Leylandii should be trimmed regularly from an early stage so that its height and width remain manageable. Light, regular clipping encourages a dense hedge and is much easier than allowing the plants to become oversized before attempting a major reduction.
As with other Leylandii hedges, keep pruning within healthy foliage. Hard cutting into old bare brown wood may leave areas that do not reliably regrow. Planning the eventual height and width of the hedge from the beginning gives the best long-term result.
