Castlewellen Leland Cypress

x Cuppressocyparis lelandii 'Castlewellen' - 'Castlewellen' Leland Cypress

Family - Cupressaceae

Size - Supposedly is the only gold foliaged conifer to consistently go over 100' in height. I've never seen one approaching this size, however it is a fast grower and I'm sure that 60' to 70' in height with a spread of 15' to 20' would not be unusual. 'Castlewellen' is reputed to be a hybrid between Cupressus macrocarpa 'Lutea' x Chamaecyparis nootkatensis 'Aurea'. The gold tone of the foliage is most noticeable in the early Spring and lasting in to early Summer. The 'Castlewellen' in this photo was a 4' plant in December, 1995. The photo was taken in early Summer, 1997.

Foliage - Flattened branchlets, quadrangular. Leaves are 1/8th - 1/4 inch in length and scalelike.

Flower/Fruit/Seed - Cone, 3/8 - 3/4" in diameter.

Bark - Reddish-brown, scaley. Usually hidden by the dense foliage.

Pests and Diseases - Bagworms can be a problem. We have began to have problems with a canker on one which will kill out entire limbs. Fortunately, as of yet this doesn't affect the overall shape of the plant.

Landscape Use - Screen, hedge, specimen. We use Leylands extensively for hedges in many locations. It provides a dense screen in a short time frame. I would think that 'Castlewellen' when used in the right location as a hedge could be attractive with the gold foliaged accent. I still hesitate to recommend this plant being grown as a solitary specimen in open exposed locations, the density of the foliage and columnar habit appears to make it a ideal candidate for a blow-over in storms.

Performance - 9 Recommended for zones 6 - 10
