So easy to grow and even easier to eat. Very delicate crunchiness that gets better and better the cooler the weather gets. Shrugs off the cold and doesn’t care for the heat. It bolts in the heat but is never bitter. An asian favorite that is becoming more popular in the U.S. Tatsoi is an excellent addition to your salad garden.
