@Kabby 3 to 6ft is about right in the ground for our zone. In my experiences if left in ground over winter the mother plant usually doesn't survive but will sprout 2 or 3 pups in late spring. To get Odora to trunk up you have to dig abd store above freezing. Plant back in spring and it will start new growth from where it left off. I currently have one 9ft tall in a pot i dont know how tall they can get. I did see one in Charleston SC that was around 12ft a few years ago.
