Awww, if my thumb turns green, I'm going to freak out! Are you able to stick your cutting in the ground outside, in a not-too-dry & shady spot? If you still have about 2 months until a frost would likely show up, that would be worthwhile I think. That's when/where it really grows @ my house. For the few months when plants have to come inside, SI doesn't do much but rest.
