Amethyst Radish
Spring Radish
Amethyst Radish is a striking heirloom bunching radish that matures in just 30 to 39 days, delivering stunning violet-skinned roots with crisp white flesh and a mild radish bite. Hardy across zones 3 to 10, this annual grows to just 4 to 12 inches tall and thrives in full sun with minimal spacing needs. It's the radish you grow when you want color to shine on the plate as much as flavor does in your mouth.

Highlights
The violet skin of Amethyst Radish creates an arresting contrast against its white interior, making it a showstopper in fresh salads and vegetable platters. Bred as a bunching variety, it produces prolifically in tight spaces, and its mild flavor appeals to those who find standard radishes too sharp. At just 30 to 39 days to harvest, you can succession-plant throughout the season for continuous color in your garden and kitchen.
Common Uses
Amethyst Radish shines raw in salads, where its violet skin creates visual contrast against greens and other vegetables. The mild flesh works well in fresh vegetable platters, slaws, and as a crunchy garnish for composed dishes where color matters as much as flavor.

Care Instructions
Direct Sow
Direct sow Amethyst Radish seeds outdoors in early spring as soon as soil is workable, and again in late summer for a fall crop. Sow every two weeks for continuous harvests throughout the growing season.
Harvesting
Harvest Amethyst Radish at 30 to 39 days after sowing, or whenever the roots reach the size you prefer (typically when they're 1 to 1.5 inches in diameter). The violet skin deepens in color as the root matures, so look for that intensified hue as a visual cue. Gently pull the entire plant from the soil or loosen the earth first with a garden fork to avoid breaking the root. Young, tender radishes are milder and more tender; leaving them in the ground longer yields larger, slightly spicier roots.
