Scarlet runner beans are quick-growing vines with typical, 3-leaflet bean leaves. They grow 6 or 8 feet tall. The bean flowers are borne in clusters like sweet peas. The edible pods that follow are long, slender, green beans.
Scarlet Runner Bean. AKA fire bean, mammoth, red giant and scarlet emperor.
Scarlet runner beans need fertile soil and adequate moisture in full sun. Plant them where they can grow up some kind of support. The beans don't need to be tied -- they twine around posts or poles.
Start new plants from seeds. Plant the large seeds directly in the ground after danger of frost has passed and the soil is warm. Plant seeds about 3 inches away from fences or posts, spacing them 2 to 3 inches apart. Thin the seedlings to a spacing of 6 to 8 inches. Seeds germinate in 5 to 10 days.
