‘Kwintus’ is an example of a flat-podded pole bean that can be picked young or left on the vine to mature for a more robust flavor.
Most beans are members of the same species, Phaseolus vulgaris, but ‘Liana’ is a different, more heat-tolerant species, Vigna unguiculata, called yard-long beans.
PETE NUTILE/JOHNNY’S SELECTED SEEDS
Easy-to-grow green beans ask only for abundant sun, warm soil and ample moisture to produce well.
These heirloom beans have colorful pods and equally colorful names, such as ‘Lazy Housewife,’ ‘Hickman,’ ‘Tennessee Indian Purple’ and ‘Blue Coco.’
‘Royal Burgandy’ is a round-podded wax bean that bears purple pods, which turn green when cooked.
Pole beans grow long vines and require a trellis.
