As I went to throw a sweet potato in the compost, remembering making sweet potato plants in school, I cut the end off and put it in water. What the heck! I thought, I need some green this winter. It has rewarded me with long shoots and now I think I'll put it in a hanging planter in the skylight and see what happens.
Unfortunately my memory can't call up what happened to my third grade plant. Maybe it died from neglect, maybe Mother got tired of watering it, Right now I have a bright spot of green and the rewarding feeling that something will grow for me.
