Raphanus sativus
Round purple radish, Gournay purple radish, purple radish: its deep purple skin contrasts with brilliantly white flesh — cut in half, it always makes an impression on a raw vegetable platter. An old spring variety, it reaches maturity in about forty days.
Characteristics:
-
Purple and white contrast: highly decorative when sliced or cut in half.
-
Excellent flavor: crisp, with a moderate, pronounced heat.
-
Maturity in 40 days: a very quick harvest, ideal for beginners.
-
Can be grown in a planter: perfect for a terrace or balcony.
Sowing advice:
-
Exposure: sunny, or partially shaded in hot weather, in a temperate climate.
-
Soil: cool, loose, humus-rich and well-drained, preferably slightly sandy. Avoid stones, which deform the root, and fresh manure, which causes it to fork.
-
Method: sow directly in the ground, 1 cm deep, spacing the rows 10 to 15 cm apart. Sow thinly and stagger sowings every two weeks. See how to sow your seeds.
Care advice:
- Thin to 4 cm apart if the seedlings are dense. Keep the soil moist but not waterlogged.
-
The decisive factor: consistent watering. A thirsty radish becomes hot, hollow and fibrous — this is the number one cause of failure.
Harvest advice:
- Harvest as soon as they have reached a satisfactory size, generally after 4 to 6 weeks. Don't wait: the root quickly becomes hollow.
- The leaves can be cooked in soup or made into pesto.
Beneficial companion plants:
Benefits for biodiversity:
- If allowed to flower, it produces white to lilac flowers that are highly attractive to bees and hoverflies, whose larvae devour aphids.
- Its green, crisp and peppery pods can be nibbled raw as an aperitif.
Uses:
- Raw with salt, with butter on bread, in salads or pickles — vinegar brings out its purple color.
Harvesting your own seeds:
Allow a few plants to flower, then form their swollen pods. Harvest them when thoroughly dry and shell them. Please note that Raphanus sativus plants cross-pollinate with one another: isolate your seed plants from other radishes. See how to store your seeds.
