Fraser fir emerges as one of the best species in terms of needle retention and fragrance, while the Norway spruce has the least desirable characteristics. Usually the Christmas tree species can be identified by the tree farmer or the salesperson at the retail lot, but occasionally it is useful for the consumer to identify species.

Size Christmas trees are available in a variety of sizes, and to properly assess the size of tree needed, it is best to consider where in the house the tree will be kept.
Consumers can expect to pay a premium for oversized trees.
There are not many large trees on the market, and the cost of producing large trees of 10 feet or more becomes extraordinarily high. These trees are hard to shear and to protect from insects, diseases, and bird and animal damage, and they take up a lot of room in the field. On many lots and farms, trees are priced according to height, so it becomes especially important to buy a tree of the right size. Some sellers also offer table-top trees, which are relatively inexpensive and may be a good alternative for a small apartment, dorm room, etc. It is very important for consumers to be able to tell whether or not a tree is fresh.
