Crimson Giant is a vigorous, fast-growing Radish producing substantial round roots with rich crimson-red skin and crisp, solid white flesh. Despite its name and ability to grow considerably larger than a standard salad radish, the roots retain excellent texture and are notably resistant to becoming pithy or hollow.
The flesh is crisp, juicy and pleasantly mild, making it excellent sliced fresh into salads and sandwiches, grated into slaws or served simply with butter and salt. Young leaves are also edible and can be used fresh or lightly cooked as a green.
One of Crimson Giant’s most distinctive qualities is its size. While roots can be harvested young like an ordinary radish, they can be left to develop towards apple size while maintaining good eating quality. This makes it a particularly productive choice where gardeners want a larger root without sacrificing tenderness.
An early and relatively heat-resistant variety, Crimson Giant is more forgiving of warming conditions than many small salad radishes. Rapid growth and consistent moisture will still produce the mildest, crispest roots.
Radishes have been cultivated for thousands of years, with their exact origins uncertain but a long history across Asia, the Mediterranean and Europe. Over generations, gardeners selected an extraordinary range of forms, from tiny salad radishes to large winter storage types.

Planting / Sowing
Sow approximately 10–15 mm deep directly where plants are to grow. Radishes develop rapidly and are best direct sown rather than transplanted.
Space seeds approximately 3–5 cm apart, allowing a little more room than for smaller radish varieties if you intend to grow the roots to their full size. Sow small batches every 2–3 weeks for a continuous harvest.
Grow in full sun during cooler weather or light afternoon shade as conditions become warmer. Choose loose, fertile, well-drained soil and avoid fresh manure or heavily compacted ground.
Keep soil consistently moist to encourage rapid, even growth and crisp roots. Although Crimson Giant has useful heat resistance, the best root quality is still produced under relatively cool conditions with reliable moisture.
Harvest young for smaller, tender salad radishes or allow roots to grow substantially larger. Even at larger sizes, the solid white flesh is notably resistant to becoming pithy or hollow.
Maturity: approximately 25–30 days.
