Those came from seed from my own plant. There are separate male and female plants so I know it didn't self pollinate. There are a few paternity candidates. I'm guessing the first 3 have a different father from the last 2.
You may want to consider an unglazed clay pot in the future, Stush. That's where I keep the mother plant. A clay pot makes it much less likely for rot problems to occur, because the water can exit through the sides of the pot as well. I use a mix of about half rock for these plants.
