|Tomato plant growing in a concrete seam on our back patio. Vegetables that decide to grow of their own accord are called "volunteers".|
|Tomato volunteers growing in a bucket of compost that I forgot to spread around. No effort was made to germinate them and no care or water was given.|
|Yesterday I harvested 5.5 pounds of tomatoes, after harvesting 3.5 lbs. two days previously. Shown here are Sweet Million and Yellow Jellybean hybrids. The yellow is an intentional color, not a sign that the tomatoes are unripe.|
Tomatoes are the single most invasive vegetable that I've ever seen, but they are by no means the only edible that can be grown literally with no effort.
|None of the dill that I grow is intentional. They don't call it "dill weed" for nothing. It grows where it wants to grow.|
|I scatter the seeds around the yard, let them come up naturally, and then retain only those that come up in convenient locations.|
|Sweet basil growing near our front door. I don't know why it decided to come up here, because I hadn't planted any of this type in the vicinity. In the upper left hand corner, you can see a volunteer sweet potato.|
Update June 13, 2014: In Part 2 of this post, I provide ideas on how to successfully manage all that can be harvested from a back yard garden, whether hybrid or volunteer.
