I have one of those that is 30 years old and was a baby from my grandmothers plant. I have seen it bloom one time. It takes up a rather large space in my bedroom but seems happy.
This one is a wax plant and is close to 40 years old, it blooms about once every 5-8 years and has itty bitty white/pink bloom clusters. Beth and I are trying to get up the nerve to re-pot it
