The bean flowers are borne in clusters like sweet peas. The edible pods that follow are long, slender, green beans. - 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.
