If you buy a real Christmas tree each year like my family does, what you should be looking for? You don't want a tree that's 3 feet taller than your ceiling, and which trees last longer, or smell better, or have softer needles that don't pinch your feet when you're walking barefoot?

Here are a few common evergreen types of Christmas trees and what they have to offer, according to an article by Marie Iannotti on gardening.about.com:

"Balsam Fir or Canaan Fir - It is usually the most reasonably priced and abundant cut tree. Dark green with a slight silvery cast, Balsams have short, flat, needles that are long lasting. Very fragrant when first cut.

Colorado Blue Spruce - They range in color from dark green to powdery blue, with stiff 1 to 3 inch needles. The needles can be so stiff they scratch, so be careful when handling. Good needle retention, but they will drop in a warm room.

Douglas Fir - A beautiful, full dark green to blue variety. It holds its needles well and is very fragrant.

Norway Spruce - Pretty tree with pore needle retention.

Scotch Pine - This is one of the most popular Christmas trees. The branches are stiff with ridged, dark green needles that hold for four weeks and don't drop when dry. As a bonus, Scotch Pine has a nice, lasting aroma."
