How to grow scarlet runner bean

When to plant scarlet runner bean

Scarlet runner bean is a fast annual twining vine grown for its showy scarlet flowers from mid-summer to frost (NC State: summer) and its edible green-to-purple pods; the flowers themselves are edible. Direct sow outdoors after the danger of frost has passed, in full sun with average moisture and good drainage; the pollen is not viable when temperatures rise above 90F, so very hot spells can reduce pod set.

Scarlet Runner Bean is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
