Boxelder, Manitoba Maple
Acer negundo 'Sensation'
Category: deciduous tree Size: medium
Mature Size: 25-45' x 20-35'
Zone: 3 Growth Rate: fast
Foliage: Maple with compound leaves.
Elevation (if known): 4,500 - 7,500'
Water: Perfers Medium to High but is drought tolerant
Soil : Almost any soil.
Sun: Full sun to part shade.
Comments: CSU lists upper elevation of 7,500' but there are many boxelders in Alamosa, but probably not this variety. Very cold hardy.Will grow almost anywhere. This is really a maple. This vareity is a male clone, so doesn't have problem with boxelder beetles. Used in Cedar Edge, Aspen, and Grand Junction. Highly suggested by Vince Urbina, Colorado State Forester. Tougher and good branching angles so not as brittle as many boxelders. Doesn't sucker. Dark pink fall color.
Warnings: Some towns don't allow boxelders, but this variety apparently doesn't have the same problems as most boxelders.
