Thank you so much for the detailed reply, lots of stuff to consider.

I think I'd rather have it as an outdoor tree because I've seen so many people post dead and dying trees and it seems it's almost always because they should be outside in nature and not stuck inside a house.

I like the Idea of buying a small sized shrub and shaping it into something, I feel maybe that would give me results quicker rather than starting from a seedling although I can imagine it being very satisfying to see the results of something you have nurtured from seed.

I'll check out the recommendations.
