I fell in lust with Tower of Jewels when I saw them in Ireland at the Malahide Castle. They were huge probably 15 feet high because I am a little over 5 feet high. You are very fortunate to have such beautiful plants.
I know, I seen them growing when we were in New Zeland and couldn't believe how beautiful they were when they grew outside. We just live in the wrong place. Have a nice day♥
