My plant is 4 years old and in a hanging basket in the filtered sun of a Vitex tree. Presently it's in the growing season and each branch gets about 1 inch longer a week. The pot is full of branches that got over 2 feet that I've broken and just thrown back in the pot. They root very easily. Here in zone 9 I only bring it into my garage for protection when winter temps drop below 38*. It's only bothered by an occasional snail that makes it up the tree to the pot and gnaws at it. It's not pretty, but interesting just the same and part of my succulent collection.
