If you guessed Glycine max, soybeans, you would be correct! In particular this is 'Midori Giant' from Nature's Crossroads, a local Indiana seed company that specializes in varieties of vegetables that do well in Indiana and the Midwest.
I've attempted to grow soybeans in my garden before but the rabbits always ate the young seedlings down to nubs, so I never saw a single actual soybean. This year my luck has changed or my rabbit deterring technique has improved because I've got nice big healthy soybean plants.
This particular variety of soybeans is supposed to have a sweet, buttery taste and be high-yielding. The more you pick the more they produce. They are flowering now.
The soybeans appear to be easy to grow. Just sow in rows like you would green beans, water, and keep the rabbits away. These will take about 75 days to start producing. I planted them on May 31st so the first tender soybeans should be ready to pick around August 14th. Maybe sooner.
In Indiana, there are thousands and thousands of acres of soybeans grown every year, yet in the book Field Crops by A. D. Wilson and C. W. Warburton, published in 1918, there is not one mention of soybeans in the table of contents or the index. But I did find information about it on page 374. "The soy bean does not yet occupy a very prominent place in the United States, though its importance is increasing rapidly." The authors further note, "Much that has been said regarding cowpea applies equally to the soy bean."

The authers of Field Crops also wrote, "Before many years, they are likely to become a common article in our diet and their cultivation is certain to increase immensely, for the uses of this plant as oil, food, and forage are very numerous."
They had no idea.
I did some further research on soybeans and discovered that 2011, this year, is the Year of the Soybean at the Indiana State Fair. Then I found out that Indiana is the 3rd largest soybean producing state and ....
