The large Brassica family is a diverse one; including broccoli, brussel sprouts, cabbage, cauliflower, kohlrabi and turnips. Reknowned for their health and nutritional properties, they are exceptionally rich in phyto-chemicals. The current world's record for eating a pound of broccoli os 92 seconds. While I am not saying that growing your own brassicas will make your children set world speed records devouring their greens; it is a fact that children will try most anything that they have helped grow in their gardens.
