The scientific name for this vegetable, 'Raphanus', comes from the Greek word for 'quickly appearing', a very appropriate name for this cress. Radish pink cress seeds can indeed germinate in as little as three days, and be ready for eating within a week.
Radish Pink Cress has a strong spicy taste, more than the radish green cress.
