Champion Radish
Spring Radish
Champion Radish lives up to its name with an exceptional combination of speed, reliability, and flavor that has earned it an AAS (All-America Selections) award. These globe-shaped roots develop deep scarlet skin with pure white, crisp interiors in just 20-29 days, making them one of the fastest radishes to harvest. The flesh stays remarkably firm and doesn't turn pithy even when radishes grow larger than typical, a trait that sets this cultivar apart for gardeners who want flexibility in harvest timing. Thriving in hardiness zones 3-10, Champion Radish grows as a cool-season annual that reaches 4-12 inches at maturity and needs just 2 inches of spacing, fitting easily into containers, raised beds, or garden rows.

Highlights
The pure white interior stays crisp and crunchy even when radishes grow large, eliminating the common problem of pithy, hollow centers that plague many radish varieties. Champion's fresh spicy-sweet flavor and firm texture make it exceptional for both raw applications and cooking, while its brilliant scarlet color creates visual drama in salads, slaws, and garnish work. With an AAS award backing its performance, this variety germinates reliably and develops uniformly, making succession planting every two weeks a practical strategy for continuous harvest throughout the growing season.
Common Uses
Champion Radishes excel in raw applications where their crisp texture and spicy-sweet flavor can be fully appreciated: thinly sliced in salads, chopped into salsas and relishes, sliced for sandwiches, or used whole as a garnish. Their firm flesh holds up well to juicing, contributing bright, peppery notes to fresh vegetable juices. The variety also performs admirably in cooked preparations including stir-fries and soups, where the flesh remains intact rather than becoming mushy. Their spectacular cherry-red color adds visual appeal to everything from tacos and tortillas to condiments and composed dishes.

Care Instructions
Direct Sow
Direct sow Champion Radish seeds outdoors in early spring as soon as soil can be worked, or in mid to late summer for fall harvest. Sow in succession every two weeks for continuous supply throughout the growing season.
Harvesting
Champion Radishes reach harvest maturity in 20-29 days, signaled by the development of full deep scarlet color and a globe shape roughly the size of a ping pong ball to small marble. Gently pull radishes from loose soil when they reach desired size; the firm flesh won't become pithy even if left slightly longer than typical varieties. Harvest in the morning for maximum crispness and store immediately in cool conditions to preserve texture and flavor.

History & Origin
“Champion Radish emerged as a significant cultivar worthy of All-America Selections recognition, a prestigious honor given to vegetable varieties that demonstrate superior performance across diverse growing regions in North America. The variety has been preserved and distributed through seed networks including Native Seeds/SEARCH, an organization focused on conservation of crop diversity, and through mainstream seed companies like True Leaf Market, which identifies it as both heirloom and non-GMO. This dual availability through both conservation-focused and commercial seed sources speaks to Champion's reliable performance and enduring value to gardeners seeking both quality and seed-saving integrity.”
