Runner bean seeds are botanically different than regular pole bean seeds. They prefer cool summer weather and will drop their blossoms if it gets too hot! They also need more moisture and cool roots all summer. Unlike snap beans, runner beans require pollination by bees to set seed. Fat, slightly fuzzy pods have a richer, beanier flavour than those of snap green beans. West Cast Seeds has two colourful varieties to choose from. Scarlet Emperor Runner Bean Seeds and Celebration Runner Bean Seeds. The flowers from both these varieties are attractive to hummingbirds and look spectacular when growing up a Pole Bean trellis.
