Introduction. Leyland cypress is a hybrid of two Pacific Coast species, Monterey cypress (Cupressus macrocarpa) and Alaska-cedar (Chamaecyparis nootkatensis) and has been given the scientific name of x Cupressocyparis leylandii. For all practical purposes, this hybrid species is sterile and must be propagated vegetatively. Leyland cypress is now grown in all southern states, and is becoming desirable for use as a Christmas tree species in that region. It retains moisture well if kept watered after being cut and has an attractive shape. However, unlike several other species grown for Christmas trees, its flexible limbs will not support large ornaments, and the species has very little fragrance. A number of cultivars (cultivated varieties) have been developed by vegetatively propagating offspring of the two parental species. Based on trials in the southern United States, `Leighton Green' is considered most desirable for Christmas Trees. However, other cultivars are certainly acceptable.
