Runner beans are botanically different than regular pole beans. 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. This may not be our best summer for growing this plants. There has also been blossom drop on tomatoes for the same reasonl.
