Also called Chinese long beans or asparagus beans, 'Orient Wonder' is a delicious and beautiful, dark green, pole bean. Seeds are slow to develop, so pods stay smooth and slender. 'Orient Wonder' is much more tolerant of weather fluctuations (cool, dry to hot, humid) than traditional green beans. It's easy to grow, prolific, and almost indestructible. Beans are most tender at 12"–18" long, even though they can grow as long as 30".
• Botanical Name: Vigna sesquipedalis
• Days to Maturity: 80 days
• Family: Fabaceae
• Native: Africa
• Hardiness: Frost-sensitive annual
• Plant Dimensions: 6'–8' vines
• Variety Information: Yard Long bean is so named because the long, slender pods can reach almost a yard in length, though they are best at 12"–18" long, before seeds start to enlarge. Long, slender, round, stringless pods hang in pairs. Commonly called a bean because it is grown and eaten like snap beans, Yard Long beans are of a different species and actually more closely related to Southern cowpea or black-eyed pea as well as mung beans. Beautiful purple flowers open in the morning beginning in midsummer.
• Type: Yard Long
• Attributes: Heat Tolerant
• When to Sow Outside: RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is at least 65°F, ideally 70°–85°F. Successive Sowings: Every 7 to 14 days up to 80 days before your average first fall frost date. NOTE: In very hot summer areas, skip sowing as high heat approaches; temperatures consistently above 90°F will prevent beans from forming.
• When to Start Inside: Not recommended; bean seedlings are sensitive to root disturbance.
• Days to Emerge: 6–12 days
• Seed Depth: 1"
• Seed Spacing: 1 seed every 6"
• Row Spacing: 36"
• Thinning: Not required
• Harvesting: Yard long beans are ready to pick when the pod snaps or breaks in half cleanly. This is when seeds have just begun to form and the pods are several inches long (depending on the variety). Hold stem with one hand and the pod with the other hand to avoid pulling off branches, which will continue to produce. Harvesting early and often will stimulate flower production for more beans. At seasonÆs end, plants are great compost material if they are disease-free.
