In our trials, the purple beans are all among the earliest and heaviest yielders. Royal Burgundy emerges very well under cool conditions, with strong, tall, purple-stemmed plants producing an abundance of light lavender flowers and clusters of round straight, 6" beans. Eaten raw, they are a dark midnight purple, very juicy and crunchy with great flavor. They acquire a deep green color when cooked, much more dramatic than that of most green varieties. 2 oz packet (approx. 200 seeds).
Outside- Bush type: 1” deep and 4-6” apart with soil temperatures above 60 degrees and after the last frost. Planting under 60 degrees results in poor germination. Pole type: Plant 1” deep and 3- 4” apart for trellis/pole growth. Drying type: 1” deep and 5-6” apart. Leave beans on the plant until the leaves are falling and pods are dry and withered
Harvest- Before the seeds bulge and beans snap easily. Pick continually to prolong production.
Tips- Water well during hot dry period and do not over fertilize which results in a surplus of foliage and low, delayed pod growth. Adding inoculant at planting time aids in a larger harvest and more robust plants. Plant seeds every 2-3 weeks for continual harvest throughout the summer.
