What type of bonsai will grow best indoor and outdoor in Western United States?

I am a beginner in growing bonsai plants and was wondering what type of bonsai trees were suitable to living either indoors and outdoors. And if you have any tips or a site where i can purchase such a tree's seeds please share thank you...|||If you are really serious about growing Bonsai's, you should read up on their care before you invest in an expensive plant that demands a great deal of attention. Most Bonsai's grow much better out of doors and because their soil is so lean, they need lots of water and diluted fertilizer to grow successfully. They also need to be trimmed occasionally. This is a plant that needs your devotion - make sure you are willing to spend the time on something so needy.
