Heirloom Vegetable. While it has been in cultivation since well before the year 1600, Round Black Spanish has almost become a forgotten variety – and its a shame too! Roots are globe shaped, about 10 cm (4″) in diameter and black skinned with pure white, very solid, quite pungent flesh. An excellent keeper. Although frost hardy, roots will not survive freezing.
How to Grow
90-100 seed/gram Sow early varieties in a sunny site as soon as the ground is workable in the spring. Winter radishes are generally sown in mid-summer. Sow seed every two weeks 12 mm (1/2″) deep and about 2.5 cm (1″) apart in rows about 30 cm (12″) apart. Keep soil evenly moist during germination and growth. Harvest in 3-4 weeks when the roots have reached the size of a large marble. One packet sows approximately 6 m (20’) of row.
