Emerald Twister Douglas Fir is a multi-stemmed evergreen tree with an upright spreading habit of growth. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

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.

Planting & Growing
Emerald Twister Douglas Fir will grow to be about 20 feet tall at maturity, with a spread of 12 feet. It has a low canopy with a typical clearance of 2 feet from the ground, and is suitable for planting under power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 80 years or more.
This tree should only be grown in full sunlight. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. It is not particular as to soil type, but has a definite preference for acidic soils. 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.
