Some friends of mine who know I am enjoying growing herbs and plants and vegetables left a stevia plant on my front door. Don't know where exactly or who, but I brought it is and repotted it and set it in a window that get sun from a little after noon to 6:00. It's acting strange, though. While both plants are a stalky 12" tall, they have very little leaves - one plant is very bare at the top and the other looks like it's trying to take off. Could I have a male and a female plant? I can attach pictures if it will help. The leaves are very, very sweet. I'd like to be able to grow the bush that it shows on the little picture tag that came in the pot......
