Oh damn thats a big container for it, which is a good thing haha. Only problem with that size container is that once in a while you're gonna wanna transplant the mother, trim the root ball up a bit, get fresh soil around her, and the larger the container the harder that is to do. Depends how long you wanna keep your mother for though maybe you won't need to do that. My mother is huge... i'll measure it now quick...

Mine is 5.5ft tall and 30" in diameter including the container. Without the container its 4ft tall. Most of the height is its big tree trunk though, its nice and lollipopped at the top.
