Potato Planter

Would this work for onions???

You could plant onions in it, but you could not harvest them through the window and keep the plant alive. When you harvest onions, you have to pull the whole plant. (You can, of course, cut off green tops to eat whenever you’d like, however.)

Besides, the green, I can’t tell what colors are named what… Help?

Sorry about that. The photos are in the same order as the drop-down list.
