The Spruce genus comprises possibly the most widely planted group of landscape evergreens with screening, sheltering, ornamental, and accent applications. Spruce are large trees, many of them growing to well over 100' in their natural habitat. Many cultivars have been developed for both size and ornamental attributes, and almost every landscape can make a Spruce feel at home. Spruce are adaptable plants and survive in most landscapes; in fact, it takes less time to tell what a Spruce will NOT do than to list all the things it accomplishes easily! Most Spruce do not accept poorly drained soil with the exception of a few northerly species such as Black Spruce which grows in low, wet environments in boreal forests. Some Spruce are sensitive to humidity, most notably the Colorado or Blue Spruce. While Blue Spruce is a beautiful tree in the garden center and garners many sales, it is susceptible to fungal disease in humid environments. My favorite is Oriental Spruce with its glossy, dark green foliage, classy habit, and attractive flowers.This tree is absolutely gorgeous after a snowfall, the white snow accenting the dark foliage. This tree exhibits the shortest needles of all the Spruces, and the foliage makes beautiful decorations.
