A wonderful birch tree selection with snowy white bark and good fall color; higher resistance to the dreaded bronze birch borer than most other white-barked birches make this a preferred variety for home landscape use
Whitespire Birch has dark green foliage throughout the season. The pointy leaves turn an outstanding yellow in the fall. Neither the flowers nor the fruit are ornamentally significant. The smooth white bark is extremely showy and adds significant winter interest.
Whitespire Birch is a deciduous tree with a distinctive and refined pyramidal form. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.
This is a high maintenance tree that will require regular care and upkeep, and should only be pruned in summer after the leaves have fully developed, as it may 'bleed' sap if pruned in late winter or early spring. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.
Whitespire Birch is recommended for the following landscape applications;

Planting & Growing
Whitespire Birch will grow to be about 25 feet tall at maturity, with a spread of 15 feet. It has a low canopy with a typical clearance of 4 feet from the ground, and should not be planted underneath power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 40 years or more.
This tree does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type, but has a definite preference for acidic soils. It is highly tolerant of urban pollution and will even thrive in inner city environments. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America.
