Mustards

True mustards are usually members of the species Brassica juncea, but there are a number of Asian vegetables of the species B. rapa that really belong in this category as well. They are included below. All these greens have a similar range of flavours and spiciness to their leaves - and can be enjoyed raw in salads, as baby greens or full size, or cooked in stir-fries, steamed, braised, or added to soups. These varieties are all relatively similar in growth form, but the leaves themselves are available as highly serrated (mizuna), huge and flat (giant red), concave (tah tsai), and even curled (giant southern curled).
All of the varieties listed here are well suited to cool season and even winter gardening. Komatsuna, tah tsai, and mizuna/mibuna are particularly hardy types.

Tokyo Bekana

Tokyo Bekana Container Gardening Easy to Grow Winter Gardening Suitable for Microgreens

CERTIFIED ORGANIC! A very nice, slightly curled mustard with light green, ruffled leaves. Although this HEIRLOOM variety can be grown to full size for cooking, the baby leaves are spectacular raw, and work particularly well in salad mixes for the market. Tokyo Bekana is sometimes listed as "small Chinese cabbage," but it's closer to lettuce in texture, with a surprisingly sweet flavour that is neither hot (like some other mustards) or bitter (like some lettuces). At full size, its delicate leaves develop succulent white petioles, making it good for bunching. As if all that weren't enough, it does not bolt in summer, and is hardy enough to grow all winter if you provide some cover.
Matures in 40 days. (open pollinated seeds)
