I've been meaning to post about this for a couple of weeks. I even took pictures, but I can't find them on my camera!
I bought a some vegetable plants a few months ago: a sweet pepper, a jalapeno pepper and a Roma tomato. To date, I have had 2 jalapeno peppers and over a dozen tomatoes. The tomato plant is still producing and I have about a dozen more in various stages of ripening.
Considering I usually kill the plant that I really like and/or have plans for, I'm pretty impressed.
