Many gardeners grow Brassica family veggies such as broccoli, cauliflower, cabbage, Brussels sprouts and kale. I also like to experiment with two other Brassicas: kohlrabi and rapini.
Kohlrabi looks a bit like a space satellite. It's low growing and forms an edible, handball sized, swollen stem near the soil surface. That's the part you eat. It was discovered in the 16th century and is popular in Europe. The classic varieties, such as 'Quickstar', are green. I like growing the purple colored, 'Kohlibri' and the white skinned, 'Beas'. There are some varieties, such as 'Superschmelz', that can grow 14 inches across. That's a lot of kohlrabi to eat! The flavor of kohlrabi is like a slightly sweet turnip and I eat it raw in dips or roast it with root crops. Plant now and stagger your plantings or you'll get lots of kohlrabi all maturing at once. Once harvested the plant is destroyed.
Another unusual Brassica is broccoli raab or rapini. This leafy vegetable hails from the Mediterranean region and from China. The name means “little turnip” in Italian. Like kohlrabi, it's related to turnips, but has a small, broccoli-like head and the leaves and small stems are cooked and eaten as well. The flavor can be slightly bitter, and very robust. I like it steamed, roasted, grilled and sauteed. It's great with pasta or with potatoes.
Rapini grows best in cool temperatures, so now is the time to start growing it. It only takes 45 days after seeding to harvest the young plants. Thin plants to 8 inches apart and harvest before the flowers bolt for the mildest flavor.
