Scarlet Emperor Runner Bean is an heirloom, open-pollinated runner bean variety with exceptional beauty and taste. Vining plants produce large, 8-12″ pods that are slightly fuzzy in appearance and texture. This variety is known for its beautiful clusters of scarlet-orange flowers that it produces throughout the growing season. Plants should be trellised and can grow up to 10′ tall in ideal conditions. We recommend using our Hortonova Trellis Netting to support tall plants as they grow. Scarlet Emperor Runner Bean has a more pronounced, meaty flavor than a traditional, green bush bean. Bean pods are tender and delicious when harvested for fresh-eating, but may also be allowed to dry for long-term storage. Dried beans have a beautiful purple and black mottling.
Beans should be planted in spring after the last frost has occurred. Beans will germinate best once soil temps have reached 65 F or higher. Optimal germination temperature is around 77 F. Seeds can require 8 to 16 days to germinate, depending on the soil temperature. For continual production, succession plant every couple of weeks throughout the spring and early summer. Plants will drop blooms or cease production in the heat of summer. Subsequent succession plantings may be made in late summer/fall, as long as enough time is permitted before the first frost date.
Direct seeding is recommended. We suggest using a #6 plate on the Hoss Garden Seeder and modifying the hole size (if necessary) to fit the seed size. Beans should be planted relatively thick along the row and thinned to the desired spacing. To maximize garden space, consider using a double-row spacing. For double-row spacing, rows may be planted as close as 6″ apart with 3′ spacing between double rows. For single row spacing, 2′ to 3′ spacing is recommended.
