Scarlet Runner Bean
Native to Central America, these vigorous vines can climb more than 10 feet in a season and will turn your yard into a festive jungle of crimson flowers. The shining, scarlet-dotted beans taste good in tacos, and the flowers drive hummingbirds wild. Win-win. Also called "Oregon Lima Bean".
Plant in full sun, about an inch deep in the soil, and near something good to climb.
