Large columnar to narrowly pyramidal conifer with dense branching, easily growing to a tree 15 to 30 m tall. The bark is reddish-brown and detaches into long, fibrous sheets later in life. The young twigs are green-yellow at first, later light red-brown. The foliage is dull mid-green. The tree grows in all soils, if well-drained and sufficiently moist, and also tolerates a lot of wind. Alongside various cultivars of Chamaecyparis lawsoniana and Thuja, it is among the most popular hedge plants. Its naturally narrow habit is an advantage when used as a hedge, and in addition, the tree prunes very well. Because of its vigorous growth, it should be pruned twice a year, creating a very dense hedge. The tree originated in 1888 from a cross between Chamaecyparis nootkatensis and Cupressus macrocarpa. New insights led to C. nootkatensis being classified in a different genus (Xanthocyparis). As a result, the hybrid species name × Cupressocyparis for C. leylandii could not be retained. To minimise the change, × Cuprocyparis was chosen.
× Cupressocyparis leylandii môže dorastať do výšky 15 - 30 m, fast growing v závislosti od podmienok stanovišťa a klímy.
× Cupressocyparis leylandii rastie rýchlo rastúci a môže dorastať do výšky 15 - 30 m, fast growing v závislosti od podmienok stanovišťa a klímy.
Správny čas na výsadbu stromu je mimo vegetačné obdobie. V strednej Európe môže byť × Cupressocyparis leylandii so zemným balom vysadený od polovice novembra do konca apríla, avšak závisí to veľmi od klimatických podmienok a druhu stromu.
