One of the oddest looking vegetables you can grow is kohlrabi. With its large, edible, bulbous stem sitting underneath big, cabbage-like leaves, it almost looks like some alien spacecraft that landed by accident in the middle of the vegetable garden! But the enlarged stem of this cabbage family member- its name means "cabbage turnip" in German- has a sweet, mild flavor that has been likened to a cross between a radish and a cucumber. It can be enjoyed crisp and raw, steamed, stir-fried or added to soups and stews. And even the leaves are edible- you cook them as you would kale.
