|The weird stem enlargement is about the size of an apple...|
Because kohlrabi is easy-to-grow and has few pests in an organic garden, helps to explain its recently gained popularity with farmers markets and local food groups. It has been grown as a crop in Europe for centuries. Grown for its weird Sputnik-shaped enlarged stem-bulb with leaves sticking out at odd angles. You can consume both the enlarged stem and its leaves.
