Leyland cypress trees are commonly planted to quickly form fence or protection hedges. However, their rapid growth (up to 1 m per year), their thick shade and their large potential size (often more than 20 m high in garden conditions, and they can reach at least 35 m) make them problematic.
Cupressaceae or the cypress family is a family of conifers. The family includes 27–30 genera (17 monotypic ), which include the junipers and redwoods , with about 130–140 species in total. They are monoecious , subdioecious or (rarely) dioecious trees and shrubs up to 116 m (381 ft) tall.
It has been determined that rooting hormones containing higher levels of IBA increase the percentage of cuttings that develop viable roots in Carolina Sapphire cypress. [12] Studies have also shown that misting at 7- to 10-minute intervals increases the amount of successful root development in Leyland cypress cuttings.
The fast-growing hybrid Leyland cypress (Cupressus × leylandii), much used in gardens, draws one of its parents from this genus (Cupressus macrocarpa, Monterey cypress); the other parent, Callitropsis nootkatensis (Nootka cypress), is also sometimes classified in this genus, or else in the separate genus Xanthocyparis, but in the past more ...

Callitropsis nootkatensis is one of the parents of the hybrid Leyland cypress; the other parent, Monterey cypress (Hesperocyparis macrocarpa), was also considered to be in the genus Cupressus, but in the North American Hesperocyparis clade, which has generally been found to be phylogenetically closer to C. nootkatensis than the Old World clade ...
