Cobra produces 20-cm long, dark green and fleshy French beans, hanging in bunches of 4 to 5. Very early, vigorous plants, highly resistant and black-seeded. Remarkably tasty. For an early harvest sow in a greenhouse or pre-sow in pots. Beans thrive in the warmth. Too much wind and particularly night frost can be very harmful. Sow or transplant after mid May in the garden. Erect poles in a roof shape, and sow approx. 5 seeds next to each pole. Later guide the plants upwards.
