I planted some Komatsuna;
(Taken from the http://www.evergreenseeds.com/komjapmusspi.html) Komatsuna is a typical Japanese leafy vegetable. It is often called Japanese Mustard Spinach in the US supermarkets. Young leaves, stalks and flower shoots are used in salad and stir-fry. It is also very popular for salt pickling this vegetable in Japan. Komatsu is a fast-growing vegetable and is ready for harvest 35 days after sowing in warm climates. Plants can be grown all year round in temperate and subtropical areas.
