Excelsa Arborvitae is primarily valued in the landscape for its distinctively pyramidal habit of growth. It has attractive forest green evergreen foliage which emerges light green in spring. The fragrant scale-like sprays of foliage are highly ornamental and remain forest green throughout the winter.
Excelsa Arborvitae is a dense evergreen tree with a strong central leader and a distinctive and refined pyramidal form. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.
Excelsa Arborvitae will grow to be about 30 feet tall at maturity, with a spread of 8 feet. It has a low canopy, and should not be planted underneath power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 50 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 or pH. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This is a selection of a native North American species.
