It's a 5 gal size. Funny thing is that the woman (worker) at the nursery set out 4 pots of this Camellia for me to choose. I was kind leaning to the tall one, but she reminded me that if you take the short one with large "waist" it look more "full" in size! Knowing it's true, still couldn't forgo the tall one (with a fair side waist). By the way, I know that if I change my mind, I can always trim top off and make it grow to side more... So that's my pick and I would love it to grow even taller.
