The Norwegian crimson sentry maple tree requires special care when planting. For more facts & information on this native tree of Norway read our guide…
The Norway crimson sentry maple is a bud sprout of the larger Norway king crimson maple. It’s smaller size makes it suitable as a shade tree in yards or as an ornamental on narrow streets. It has a narrow ovate shape and at full maturity attains a height of about 40 ft. and a width of about 25 ft. It has a slow to medium growth rate and a life span of at least 100 years.
The tree sports deep burgundy foliage during spring and summer months which turns bright gold in the autumn. It is deciduous and has yellow blossoms in the spring before the leaves come in. The leaves are dense and lobed and the canopy is typically about 5 ft. above the ground. The bark is furrowed and black in color adding little to the tree’s appeal.
Planting Norway Crimson Sentry Maple
The sentry maple prefers full sunlight and average to moist soil conditions. It will grow in acid, neutral or alkaline soils without difficulty. Unlike some trees, the sentry maple seems indifferent to urban pollution making it an excellent choice for city dwellers. Since it will reach a height of 40 feet at maturity, it should not be planted too close to power lines.
Spacing Norway Maple
Like other maples, this tree may be subject to powdery mildew if it does not get enough air circulation. While less susceptible than Norway king crimson maple, it is important to take this into account when planting the tree. The tree makes an excellent windbreak or border specimen but should be spaced at least 15 to 20 feet apart to allow for growth.
In the United States, the Norway crimson sentry is hardy in growing zones 3 through 7. It is not suitable for extremely arid or wet areas. It is drought, deer and wind tolerant, but does not grow well in excessively hot climates. It is fairly disease and pest resistant, but can be infested with aphids or infected by fungi especially when young or newly transplanted.
The Norway crimson sentry is not a dwarf, but with it’s comparatively narrow and compact shape makes an excellent ornamental or shade tree. Its red foliage makes it an attractive addition to any yard or garden. It is an especially good choice for city dwellers as it tolerates all types of pollution well, but it must be planted in direct sunlight to thrive.
