Q.Ocotillo
I have an ocotillo that is 13 years old and it grows what I would call suckers. They grow off of a stem and grows down. If I let them go, the plant ends up looking like an octopus. I have never seen one in the wild do that and I have asked the nursery that I bought if from and they do not know what causes it or what to do about it.
A mature Ocotillo can grow to 15 feet tall and the same width.
It is not uncommon for the plant to send out canes that will lie close to the ground as the base widens.
A mature plant can grow up to 60 canes or branches.
