PRAIRIE SKY  POPLAR

• Botanical name: Populus canadensis 'Prairie Sky'

• Origin: A cross made between a vigorous native selection of Cottonwood and the columnar Theves Poplar. The cross was made by Dr. Wilbert Ronald in 1976 at the Morden Research Station, Agriculture Canada.

• Hardiness: Zone 3 (Canadian and USDA)

• Growth Rate: The growth rate is very fast. An average of 4 feet in height growth and at least 1” of caliper per year can be expected on a fertile site, over a 10 year period. Young trees can show tip kill in cold winters due to the rapid growth rate.

• Description: A male tree with a narrow, upright growth habit and small lateral branches. It maintains a dominant central leader and reaches a height of 65-80 feet. The leaf shape is similar to that of the native cottonwood.

• Landscape Value: Well suited for naturalized areas and well adapted in areas designated for screen or buffer zones.
