Description

(Psophocarpus tetragonolobus) Pole bean. Lush, tropical vines climb skyward, draped in soft lavender blooms that give way to crisp, star-shaped pods with a mild, green-bean flavor and a fun, crunchy bite. This rare Japanese selection was the answer to years of searching for an earlier-producing winged bean—setting pods by August and rolling strong until frost. Popular in Okinawa and adapted beyond typical day-length limits, it thrives in warm conditions and brings serious production once it gets grooving. Slice the pods and you get perfect little stars—ideal for stir-fries, soups, or simple steaming. Equal parts exotic beauty and kitchen-ready goodness, this one turns any garden into a far-out tropical feast.

Growing Guide

When to Grow

The best time to plant Urizun winged beans is after the last frost date in spring when the soil has warmed to at least 70 F. The perfect temperature for growth is 75-95 F. In USDA zones 9-11, you can plant it directly outdoors. For cooler regions, consider starting seeds indoors and transplanting them after the danger of frost has passed. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

To improve germination, soak the seeds for 1-2 hours before planting. Sow the seeds 1-2 inches deep and space them 6-12 inches apart, with rows 3 feet apart. If starting indoors, use a soilless mix and transfer the seedlings to the garden once they have their first true leaves and are large enough to handle​.

How to Grow

Ensure the plants receive regular watering, keeping the soil consistently moist but not waterlogged. Mulching can help retain moisture and suppress weeds. While winged bean plants are not heavy feeders, incorporating compost or a balanced fertilizer at planting time and again during pod development can be beneficial. Pruning is generally unnecessary, but trimming the tops of the vines can encourage bushier growth.

How to Save Seeds

  • Winged beans are self pollinating and will not cross with other legumes.
  • Saving seeds is easy. Allow pods to fully mature and dry on the plant; collect the seeds as the pods split and then store them in a cool, dark, dry place.

FAQ

What pests and diseases should I watch out for?

Common issues include aphids, spider mites, and powdery mildew. Regular monitoring and organic pest control methods are recommended.

When should I harvest the Urizun winged bean pods?

Harvest the pods when they are young and tender, at about 6 to 8 inches long. Urizun begins bearing around 120 days from sowing; in our Missouri climate that means August, with heavy production continuing until frost. Overly mature pods become fibrous and less desirable.

How can I store the harvested Urizun winged beans?

Fresh pods can be stored in the refrigerator for up to a week. For longer storage, consider drying the beans​​.

  • Sky-blue blooms: Large lavender to sky-blue flowers that look great on a trellis.

  • Whole plant edible: Pods taste like asparagus; leaves, flowers and tubers eaten too.

  • Heads up: Very slow to start; soak seed, keep it warm, allow a long season.
