Several weeks ago I received a brown twig with a couple leaves. It took off real well and then it withered. I moved it to another location where it would get more light and temperature variation. It didn't do anything. I was about to toss it when I saw that beneath the LFS there was another growth point, with two more leaves. I tossed it under the Grolite, amid the LFS. It's hanging in there but now I see another growth point, with two more leaves. Is it normal to have multiple growth points?
