Plant. Mine started out 3 - 4 inches tall. And now about 6 months later they are over a foot tall.
Mine wasn't too big, it was about 6" tall if that. But I had one mother plant and two babies that I broke off the root shortly after I received this. I've had mine for almost a year now and it's been growing and multiping great. I'd imagine that each plant will be different but, I'd order from them again.
It does come in a small pot.
It doesn't need a lot of water. Check it for moisture at least each week. Best to keep it in the sun. Mine is doing great even though I neglected to water it a couple times. It is good for the skin as well. For expert advice you can look it up on line.
