Most of these are described as 20 inches or less in height. A few may be a bit taller. Lots to choose from! I would say that if you prefer taller lilies (3 ft+) you should use larger pots, both for balance of form and again for stability. Some of the tall lilies can get pretty heavy when in full bloom!
