Scarlet Runner beans

Seeds from previous crop, destined to be planted against the mesh fence on the other side of  the asparagus beds.

These beans grow thickly and vigorously, putting out dense foliage. The root system forms a sort of tuberous clump underground, and appears to be deciduous. i.e. in theory, once planted, they'll keep on going.

Despite their showy appearance, they're delicious.
