Thank you, Mike. The registered height on 'Sears Tower' exceeds the upper height limit I've set
. Since I'm planting in what I call 'patio containers' the plant itself is already elevated 2' above ground level. If the really tall ones reach their registered height, the blooms will be above my head and I used to be 6' when I was younger. The current level of my shrinkage allows me to get some tall ones, but not as tall as 'Sears Tower'. It always looks good in photos, though. The ones I've had in pots have reached or got close to their registered heights after the plants have been established for a year. I thought maybe they wouldn't do that growing in pots, but the preliminary indication is that they will.
