Hybrid Poplar

test

Attractive, fast-growing trees available in several forms. Characterized by leaves that shimmy even in slight breezes and cottony, wind-dispersed seeds. Good for screening, windbreaks, and background planting. Most have good fall color. Hardy to at least zone 3, and Cottonless Cottonwood (Populus deltoides Siouxland, 22437, 22438) is zone 2 hardy, non-flowering, rust-resistant, and grows 70 to 80 feet tall when mature. It is an excellent shade tree. Hybrid Poplar (Populus x euramericana, 22439, 22440) is an extremely fast-growing hybrid for screens, shade, and firewood. It is non-blooming, does not produce seed, and can reach 60 to 80 feet at maturity. Theves Poplar (Populus nigra Afghanica, 22432, 22433) has a narrow columnar habit and grows to 60 feet tall. Poplar is generally easy to transplant and bare root trees are planted in spring 4 to 8 weeks before the last frost. Use a hole 12 to 18 inches deep and wide amended with compost or other organic matter. Plant trees with the roots slightly deeper than when growing in the nursery.
