Heirloom Vegetable. There is no doubt about it, Sparkler is a beautiful round summer radish. The top half is a fine scarlet colour with a rosy ‘sparkling’ edge bordering a pure white bottom half. Tender yet crisp flesh on what is possibly the finest market radish offered. Irrigation is essential for best flavour and root development.
How to Grow
90-100 seed/gram Sow in a sunny site as soon as the ground is workable in the spring. 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.
