aspect slopes that are protected & that receive moist air from waterways. It cannot tolerate extended freezing or excessively dry soils & heavy winds dry
it out. It is sometimes seen in urban environments where it can be given plenty
of water, a little shade & a good misting every day as its seedlings are established. It has needle-like leaves ½”
- 1’” long in two flat rows on the stem, thick reddish-brown bark
