Leyland Cypress (Cupressus Ã— leylandii, syn. Ã— Cupressocyparis leylandii). Hybrid between Monterey Cypress (Cupressus macrocarpa) and Nootka Cypress (Cupressus nootkatensis, syn. Callitropsis nootkatensis, Chamaecyparis nootkatensis). The ease with which this hybrid occurs - 20 different clones of independent origin from seed are known - is a strong pointer towards a close relationship between the two parent species, despite their often being cited as being in different genera. Widely planted in small gardens completely inappropriate to its large size at maturity. This specimen is 36m tall, with a trunk over a metre in diameter. Let the buyer beware!
