I was given a few plantlets last year and they grew to about 2 ft. and looked lovely. This year they have come back with several more plants and they just kept getting taller and taller. Most of them are about 5 ft. tall, but there are a few that are over 6 ft. tall, almost 7 ft. Is this a normal height for these plants?

I took this picture yesterday, after reading this thread. I had my DH pose next to them to show you the height. The one next to him has it's base about 6" lower than were he is standing. The tallest one is to the left of my Ti plant, it is growing up into the branches of the buddleia, it's base is even lower than the other one.
