Kohlrabi
This is the mystery vegetable since there is nothing like it in the plant world although it is thought to have derived from wild cabbage. The closest vegetable in taste is the core of the cabbage. The plant has an edible "bulb" produced on a stem above the ground. The leaves sprout from around the top of the bulb. The flesh is mild and crisp. The bulb should be peeled before eating. Direct seed in rows ΒΌ" deep, with 2 seeds per inch. SPace rows 18 inches apart. Cover seeds with sand or compost for faster germination. Thin seedling to 4"-6" apart. Begin to harvest when stems have swollen to 1"to make room (6"-8" apart) for remaining bulbs to expand.
