Kohlrabi is another name for our not-so-popular Knolkhol. It belongs to the same family as Cabbage and Cauliflower(Brassicaceae). The Whole plant is edible however, it is mostly used for its bulged swollen stem. It can be eaten raw as well as cooked. Though it prefers a cold weather, it does moderately well for our Bangalore weather.

Knolkhol makes a good candidate for a kitchen garden because of its quick maturity. It comes to harvest in just about 50 days. Another interesting part is that it comes in different colors  :D.

You get them in White, Green and Violet/Purple.

Growing Knolkhol is also very easy. Buy good quality seeds to begin with. You can get them Lalbagh Nurserymen Co-op.

Seed starting:

Take seed starting mix(cocopeat) and moisten it.

Sow the seeds, 1/4 inch deep in the media.The media you see in the pic below is vermiculite. Cocopeat/perlite/sand or a combination of those will do as well.

The seeds germinate in about 4 days.
