How to select Christmas tree.

Natural trees[edit]

See also: Christmas tree cultivation

The most commonly used species are fir (Abies), which have the benefit of not shedding their needles when they dry out, as well as retaining good foliage colour and scent; but species in other genera are also used.

In North America, Central America and South America most commonly used are:

• Douglas-fir Pseudotsuga menziesii -- reasonably priced tree and creates that great smell

• Balsam fir Abies balsamea

• Fraser Fir Abies fraseri -- beautiful scent

• Noble fir Abies procera -- sturdy
