As your plants mature they will get taller, bigger,wider each year.

After a few summers the plants will most likely be a their peak size for the zone your are in.....then winter happens and you have to start over again...overwintering progressively larger/wider plants each season.

Expect your plants to be at max size in our zone with minimal indoor winter care in 3-4 grow cycles...by then you might have a flower or two
