Cottonwood, Narrowleaf Populus angustifolia Category: deciduous tree Size: large Mature Size: 30 - 50' by 20 - 30' Zone: 2 - Growth Rate: fast Foliage: willow-like leaves Elevation (if known): To 9,000' Water: Medium to heavy. Soil : Sun: Full. Comments: Works well in Alamosa, but note warnings. Best in natural areas along streams. Young bark is green. Provides large shade canopy. There is one called ‘Creekside’ that has been grafted to P. acuminata rootstock (lanceleaf cottonwood) to prevent suckering. Warnings: Cottonwoods are notorious for suckering. Female trees produce vast amounts of cottony seed; nurseries only sell males. Some resources says doesn't sucker. Mine doesn't produce cotton but suckers like crazy. Alamosa Tree Board Recommended? yes Street Tree? no Street Tree Conditions: Only for large spaces where suckers are not a problem. CO/NM native? yes Native to: Midwestern US & Canada Known Locations: Many in Alamosa; Loser garden has one planted in 1997. Suckers like crazy around the garden. I would NOT replant!
