There are many different types of Christmas tree styles, each of which goes with a certain holiday decorating theme. Below we'll outline the main types:
Classic lush green tree
These are made to mimic pine or spruce trees and often come in deep or bright green shades. This is the classic triangular, lush tree you think of when you think of Christmas trees. These go well in classic or rustic themes where natural textures or quintessential holiday looks dominate.
Thin fir style
These mimic fir trees and often have a characteristic lighter color with a smaller diameter. These are good for small spaces or modern and minimalistic styles that are going for a more understated and contemporary look.
Bushy fir
Not all fir trees are thin. Some are bushy and have a deep texture with branches in a wide variety of lengths. They also tend to have a lighter color. These look good in rustic themes due to the texture, light-colored modern themes or even classic themes looking for some texture.
White Christmas trees
These trees have the branches in a shimmery white shade. They look good in modern styles, industrial styles or designs that otherwise follow a color scheme, like monochrome Christmases. These are good if you're trying to get far away from the natural theme.
Tinsel trees
Along the same line as white trees, tinsel Christmas trees are good in modern, light or industrial themes. These were also very popular in the mid-20th Century, so they're good for a period Christmas.
Black Christmas tree
You can't get much more of a statement look than a black tree. These are also more common in modern styles. You also might use it in a funky, artsy style and put boldly colorful lights and ornaments on it.
Natural trunk style
These styles of trees often look like something you pulled right out of the forest, often with a natural-style trunk showing in some way. The tree itself might also be smaller and the branches a little sparser. These styles look great in rustic, coastal, Scandinavian or minimalistic Christmas themes.
Colors
This category covers any tree where the branches are a bold color, like blue or pink. Use these for funky and artsy styles or monochrome designs.
