CloseLarge clusters of beautiful scarlet flowers and rapid, vigorous, sprawling growth.
The long pods are tender and tasty when picked small. If undisturbed, the roots may overwinter and re-grow the following spring in mild winter areas. Even if it doesn’t come back as a perennial, the seeds are large and easy to harvest and dry for future plantings. The seeds are black, streaked with purple. Grow Scarlet Emperor runner beans up a tall, strong trellis, and it will reach 3m (10') or higher by mid-summer.

Season Warm season
Exposure Full-sun
Timing
Direct sow from late spring to early summer. Try to plant during a warm, dry spell. Soil must be warm – if it is not warm enough, seeds will rot, especially our untreated seeds. Optimal soil temperature: 21-32°C (70-90°F).
Starting
Seeds can be started indoors, or sowed directly. Set seeds 7-10cm (3-4″) apart and 3.5cm (1½”) deep at the base of a support. Plants will climb by twining around almost anything. Try rough poles, lumber, re-bar, or build a strong trellis 2-2.5m (6-8′) tall. Seeds will sprout in 8-16 days, depending on soil conditions.
