One thing I've always admired about some people was their ability to grow food from produce they bought at the grocery store. I always found this an extremely nice trait in people, even if they are growing the plants simply for aesthetics.
The idea of buying a fruit or vegetable and growing a plant from the seed, ends, or top of it just wreaks of thrift and frugality. Sadly, since I rent a second floor apartment with no balcony and no window boxes allowed (on the outside), I'm limitted in what I can actually grow.
I'll be adding different plants that can be grown for food purposes and ones that can't as time allows. They will be tagged as "growing food".
