How to Grow Purple Beauty Radishes From Seed

Updated July 2026

Purple Beauty is a striking round radish with vivid purple skin and crisp, bright-white flesh inside. Its color holds well and makes an eye-catching addition to salads and platters, while the flavor stays mild and pleasantly crisp. It matures in about 28 days from a cool-season sowing. Just as easy to grow as red radishes, Purple Beauty adds unexpected color to the garden and the plate.

This is the quick guide to Purple Beauty. For the full step-by-step on starting seeds, sowing, feeding, and troubleshooting radishes, see our complete guide to growing radishes from seed.

Quick start

Direct-sow Purple Beauty seeds half an inch deep and one inch apart in cool spring or fall soil. Thin seedlings to about 2 inches apart and keep the soil evenly moist. Harvest the round purple roots at about 28 days, once they reach one to two inches across, for the crispest flesh and boldest color.

Best tip

Purple Beauty grows just like a red salad radish, and its color is deepest when the roots grow quickly and get picked on time. Sow in cool spring and fall weather, keep the soil evenly moist so growth never stalls, and thin early. In hot-summer regions, grow it as a spring and fall crop; heat mutes the color and turns the flesh hot.
