Lawson Cypress (Chamaecyparis Lawsoniana) hedging of this species is now more common than plantations of it. Excellent wind break hedge when grown together with regular maintenance. Nevertheless it is a respectable forest tree in its native SW Oregon and NW California. Trees 50 metres tall are known, a salutary lesson for hedge planters! When Lawson Cypress (Chamaecyparis Lawsoniana) was introduced to Britain in 1854 it enjoyed early popularity as a timber tree, but was soon overtaken by western red cedar. Once established as a horticultural plant it began to produce sports and aberrations of every colour and form imaginable. These have become the stock-in-trade of many nurserymen. A massive 524 named plants have been listed and new ones are being selected all the time.
