Mother of Thousands (Kalanchoe daigremontiana) has both the common name "Mother of Thousands" and "Mother of Millions". There are so many Kalanchoes though and I'm sure a few probably have that same common name. There are so many listings in the databse: The Kalanchoes Database. Maybe if you can find the exact one you are seeking, one of our members would have it listed for trade?
