I love white trees. I love green ones too. I also like the silver and even the black ones. You can never have too many trees. I have 13 trees that I put up in our house ranging from 4' to 10'.
I have two seven foot white trees in my kitchen decorated in white and silver with white lights. The entire kitchen and nook are done in silver and white and it looks like a winter wonderland. I also have two three foot white trees in there decorated with the silver and white. Everyone who has seen them say that they are beautiful.
If you have the place for one, I would definitely recommend it. I have had some white wreaths yellow a bit with age over the years, but ones that I bought in the last 5 years seem to be holding up pretty well.
