Most people who square foot garden aren't doing it in containers (though some are). Most "boxes" don't have bottoms, but go on the ground. That gives the roots more room than the top 6 inches and access to soil nutrients. I do think you can get more than two, if only because the are very short-lived and don't mind being crowded when planted in the ground. Maybe I'm wrong, but I'd guess you could put 4 in there anyway and get some sort of worthwhile harvest if you were careful about soil, water, and feeding. I'm really just guessing. But given the price of bean seeds, I'd give it a go. What have you got to lose?

finally found my pickled carrot recipe ... it was in my cooking recipe data base because it is NOT for canning, but as noted it keeps up to a month refrigerated. It' best with fresh harvested carrots, but is not bad with regular store bought. I usually spring for organic. PICKLED CARROTS Makes 10 servings Source: Gourmet, November 2003 (originally November 1985) Good snack. Keep chilled in an airtight container up to one month. 1 pound carrots cut into 3 1/2 x1/3 inch sticks 1 1/4 cups water 1 cup cider vinegar 2 cloves garlic lightly crushed 1 1/2 tbsps dill seeds 1 1/2 tbsps salt Blanch carrots in nonreactive saucepan of boiling salted water, then drain in a colander and rinse under cold water to stop cooking. Transfer carrots to a heatproof bowl. Bring remaining ingredients to a boil in saucepan, then reduce heat and simmer 2 minutes. Pour picking liquid over carrots and cool, uncovered. Chill carrots, covered, at least a day for flavors to develop. can't recall who was asking about okra, here one that's seasoned a bit differently from the NCHFP http://www.epicurious.com/recipes/food/views/Pickled-Okra-108764

You might start with African violets. They have a long and complex hybridization history, so crossing any two varieties is likely to give you lots of seedlings with considerable variation. Some offspring may throw back to wilder types with what are considered undesirable characteristics (e.g., dropping flower petals after only a couple of days), but others will surprise you. I assume you have a diagram showing the reproductive parts of the flowers and can get pollen to the stigma. African violets have pollen sacs that often have to be cut open with a fine and sharp knife blade to get the pollen out. Once you have delivered pollen from one plant to the stigma of another, the ovary will swell up fairly dramatically. Wait a couple of months, and the ovary will turn brown and begin to split open. Harvest the abundant, dust-like seeds and set aside for a few days to let them dry. Then sow them at the surface of African violet mix and keep continuously moist till seemingly thousands of tiny seedlings appear. I keep the seedbed in a Zip-Loc or similar sealed plastic bag till I see sprouts and then prick out some of the plants for trnasplantation, as many as I can make room for. Keeping the seedlings in the bag after they sprout can lead to rot, so I remove them into the air and set them in a bright location out of direct sun. A north window is ideal. Growing garden hybrids is trickier. Many cultivated plants from the local Home Depot or seeds from the large seed companies have been hybridized to produce the large, showy flowers many gardeners seek out. Many of these varieties will revert to a much less attractive wild type if hybridized. You could experiment with crossing different types and colors of petunia to start, since they are easy to cross and produce a lot of seeds quickly. From seed to blooming adult can take just eight weeks or less if you care for the seedlings properly. Give it all a try. I hybridize a type of succulent plant called Haworthia from South Africa and get some very cool plants when I achieve a successful cross between two different species. biosparite

Tepary beans, limas, and yard longs are all different species, and will not cross. You can grow them side-by-side & still get pure seed. Each could possibly cross with others of the same species, if they were nearby. Teparies are adapted to hot desert climates, and are not commonly grown in the North... so it is unlikely that anyone near you is growing them. Yard longs are are botanically cowpeas, and could possibly cross with yard longs / cowpeas grown by your neighbors... but this too is unlikely. Limas are another story. Their blossoms are very attractive to bees, and if one of your neighbors is also growing limas, a cross or two is possible. My rural garden is over 1/4 mile from any other gardens, and I got a lima cross one year. One note regarding tepary beans. Some of the varieties in circulation carry bean common mosaic virus (BCMV). Until you know if your stock is infected, I would recommend planting them some distance from your other beans as a safety precaution.
