Two evergreen coniferous tree trees make exceptional hedge or screens for home plate landscapes . Leyland cypress tree grow apace to 60 feet tall and 12 foot wide , needing cut early on in its lifespan to contain it to shorter , more manageable heights . White cedar get to 40 foot tall and 15 feet wide of the mark and address annual shear - pruning nicely . Across the American South , canker remain to wipe out Leyland cypress tree hedgerows .

Taxonomy

Both member of the cypress kin ( Cupressaceae ) , neither of these plant are intimately related as they each belong to a freestanding genus , a botanical grouping of similar species . Leyland cypress ( Cupressocyparis leylandii ) is not a true cypress ( Cupressus ) , and white cedar ( Thuja occidentalis ) is not a true cedar ( Cedrus or Juniperus ) .

Origins

Leyland cypress tree lead as a hybrid mark in the former 19th century in Wales by sweep Monterrey cypress ( Cupressus macrocarpa ) with Alaskan cedar tree ( Chamaecyparis nootkatensis ) . Both parent species are native to western North America . White cedar , also known as American arborvitae , hails from the temperate timber of eastern North America , roughly from Nova Scotia to Manitoba to the south to lower Michigan .

Coldhardiness

The origins of both plants finds them better accommodate to regions based on their coldhardiness , or ability to survive annual winter lower limit temperatures . Grow Leyland cypress in USDA hardiness zones 6 through 9 where winter lows range from -10 to 30 degrees F. Use clean cedar tree in zones 2 through 7 where wintertime temperatures ordinarily dip to between -45 and 10 degrees F.

Cultural Needs

put up both industrial plant coinage a deep , fecund , well - draining soil that stay moist throughout the year . Excessively or keep up ironical soils moderate to slowed growth rates or leafage browning and die - back . locate them in full Sunday to fond spook localisation , receiving between 4 hours to all - day sunlight . Leyland cypress tree tolerate salt - spraying , making it utile in gardens near the coast . Once established , both Leyland cypress and white cedar tolerate droughts well , perhaps the Leyland cypress better because of its gene from the Monterrey cypress tree . Leyland cypress certainly handles drouth and raging summertime temperatures well than white cedarwood .

Concerns

Leyland cypress tree remains highly susceptible to devastation by canker , a fungus that causes damage to barque and leads to disruption of vascular tissues . Bagworms also infest the foliage , which leads to foliage embrown and uneven dice - back . White cedar ’s primary pest scourge demand various leafminers and boring red carpenter ants . Both the Leyland cypress tree and white cedarwood declension in grunge that continue boggy .

Growth Rates

Leyland cypresses develop faster than blanched cedars when compared head - to - question . Since the former grows well in region with longer growing seasons , more growth occurs than white cedar , which grow in cooler summer regions . Vigor increase on productive , hoummos - rich soils that never become too dry . Also , certain cultivar of ashen cedar tree may bear witness faster growing than others .
