Got a few tiny tomatoes in a tub with a ripening banana. The banana's do cause the peppers and tomatoes to turn red. Hope they don't all taste like bananas. Found a good article about why gardening doesn't really save most people any money.
After a few years of vegetable gardening, next year I might try begonias or something that flowers. Perhaps a few flowers and some cayenne peppers. Flower gardening would be a novelty. Except for cactus, African violets and an aging geranium, I haven't tried it since I was a tot.
