Chinese Vegetables: Warm-Season Varieties

Bitter melon1

Many Chinese vegetables–also known as Oriental vegetables– are well suited for warm-season growing. Grow these crops from spring through the end of summer.

These crops are favored in Chinese and Asian cooking, and they are easy to grow. Most are fast-growing and suitable for small gardens and containers.

Chinese vegetables can generally be broken into three groups: those easy to grow in temperate regions with cool and cold winters, those that require higher temperatures and long-growing seasons–sub-tropical plants, and, finally, a small group of water vegetables, tubers, and herbs. The crops listed here are well-suited for growing in the temperate regions of the Northern Hemisphere.

Warm-season Chinese vegetables

Vegetable amaranth (Amaranthus hypochondriacus for seed/ Amaranthus tricolor for leaf). Amaranthus tricolor also known as Chinese spinach, edible amaranth, hiyu, and callaloo. Cook greens like spinach. Sow in spring; can be grown in summer. Sensitive to frost; germinates best in warm soil. Sow ¼ inch, row 18 inches apart. Greens ready in 50 days; 100 days for seed. Try varieties: Red Stripe Leaf, Tender Leaf, All Red.

Arrowhead (Sagittaria sagittifolia). Also called Chinese arrowhead, swamp potato, and kuwai. The tubers of arrowhead are eaten; bitter when raw but full-flavored like a nutty sweet potato when cooked. Roast, or boil like a potato. Best grown in boggy soil set about 3 to 6 inches below the surface of the water; leave room for roots to grow. Harvest tubers all season long. Store for winter in a water garden that will not freeze.

Adzuki bean (Vigna angularis). Also known as aduki bean or red beans and in Japan as azuki. A sweeter flavor than most beans. Young beans can be served like snow peas after brief cooking. Puree after simmering dry beans. Cook dried beans like navy beans–just simmer for about 40 minutes until tender. Sow ½ inch deep; sow 2 to 3 inches apart in rows 24 inches apart; no need to thin. For green beans harvest when beans just begin to show in the pod; for dried beans allow to mature, for about 120 days.

Mung bean (Vigna radiae). Also called Chinese green bean and known in India as green gram or golden gram. Not commonly grown in home gardens; mung beans are easy to sprout and often used for sprouting. Young pods can be eaten like snow peas; shelled beans can be boiled. Sow when the danger of frost is past. Sow ½ inch deep and 6 to 8 inches apart in rows 24 inches apart. Grow on a pole, fence, or trellis. Harvest immature pods to eat in pods after 90 days; for dried beans, let bean pods dry on the plant and harvest at 120 days. Varieties: look for green or golden.

Yard-long bean (Vigna unguiculata ssp. sesquipedalis). Also called asparagus bean and Chinese long bean, Green beans can be boiled briefly and served; also use in stir-fry. Beans can also be dried. Plant when soil has warmed in spring and no danger of frost. Sow seed ½ inch deep, allow 4 inches between plants. Grow on poles or on teepees. Best harvested when immature when bean has barely swollen in pod. For dry beans harvest about 90 days after sowing. Try varieties: 3-Feet Plus, Chinese Red Noodle Beans, Canton White Pod.

Water chestnut (Eleocharis dulcis). Water chestnuts are not nuts but edible roots grown in rich very wet soil; the “chestnuts” form in the mud at the base of stems and are about the size of a walnut. Used for their nutty flavor and crispness. Eat raw or cooked, added at the end of cooking. Slice thin for salads, stir-fry, or add to soup. Grow in soil immersed about three inches below water level. Water chestnuts mature in about six months but can be gathered sooner. Store roots out of water in a cool, moist place where they won’t freeze.

Cilantro (Coriandrum sativum). Fresh leaves tender and young will add zest to salads and also can be minced and sprinkled. Use cilantro at the end of the cooking cycle in stews or soups. The seed–called coriander–has a spicy citrus-orange flavor; use to flavor breads, puddings, and pastries. Sow seed from early spring through late summer. Barely cover seeds with soil; thin to 6 inches apart; sow successively for fresh cuttings. Leaves are ready for harvest in 50 days, seeds in 90 to 100 or more days. Try varieties: Asia Choice, Glory TW, Slow Bolt Winner.

Asian cucumber (Cucumis sativus). Also called Chinese cucumber or long cucumber; burpless cucumbers. Served sliced and marinated, stuffed, sautéed, or cooked with other vegetables and meats.

Try varieties: Hybrid Crisp Winner, Hybrid Malai, Hybrid White Star.

Daylily (Hemerocallis fulva). Flower buds are eaten fresh and dried, sometimes served as “golden needles.” Buds are cut into lengths to serve with meat and vegetables; stir-fry or cook tempura-style. Daylilies grow from fleshy tuberous roots. To plant, set fleshy roots just below soil level, dig in compost, and water well. Harvest buds when they are plump but before they open. Fleshy roots and young leaves can also be eaten. Varieties: look for Hemerocallis fulva and Lilium lancifolium.

Chinese eggplant (Solanum melongena). Also called aubergine. Asian eggplant is not bitter and does not need peeling. Serve fried, baked, or roasted or stuffed and roasted; also can be pickled. Eggplants require a long, warm season; usually started indoors a month before setting out; do not set out until the weather is warm and settled at least two weeks after the last frost. Sow ½ inch deep. Requires side-dress feeding and regular, deep watering during the season. Ready for harvest 60 to 75 days after transplanting into the garden; best picked immature when skin is glossy and smooth. Try varieties: Ping Tung, Hybrid Purple Excel, Ma-Zu Purple.

Ginger (Zingiber officinale). Grown as a spice: use ginger root with main dishes and desserts, salad, or stews. Ginger adds zest to many meat dishes; it eliminates fishy odors or seafood. Best started from root indoors and planted outdoors in late spring when all danger of frost has passed. Start new planting from a clean root cut into 1- to 2-inch pieces with at least one “eye” per section. Plant 2 inches deep in a 6-inch pot. The plant will develop numerous reedy shoots. Harvest shoots anytime after the plant is 3 inches high. Harvest immature, rosy-pink roots as “green ginger” in three to four months. Mature roots can be dug up after the plan has died back.

Fuzzy gourd (Benincasa hispida var. chieh-gua). The outside coat is fuzzy like a peach and must be removed. Also called hairy melon, hairy gourd, and hairy cucumber.

Grow from a rhizome in full sun; set rhizome in horizontal position sprouts will point upward at a slight angle. A single plant requires a 25-gallon container and will grow to fill space. Set root in a pot with from 6 to 10 inches of warm water above the soil line. Once planted keep in warm, not cold, water. Growing season from late spring to early autumn. Buds, flowers, and seedpods all come to harvest at the same time. The root can grow to 4 feet and can be harvested in segments; break apart roots to store in winter. Store in winter where roots will not freeze.

Luffa (Luffa acutangula, L. cylindrical). The leaves and flower buds are edible when young; the fruit is edible when immature. Prepare the fruit like zucchini: simmer, stir-fry, stuff.
