Fire Candle Radish is an Italian heirloom that defies everything you think you know about spring radishes. Long and slender like a Daikon rather than the round, peppery roots most gardeners expect, this variety stretches 8-9 inches at maturity and matures in just 30-40 days. Growing in hardiness zones 3-10, it thrives in full sun and produces one of the most vibrant, unique radishes available, resembling a red carrot more than a traditional spring variety. Its narrow, elegant form and quick timeline make it perfect for gardeners seeking something genuinely different from the ordinary.

History & Origin
“Fire Candle Radish traces its roots to Italy, where it developed as a regional heirloom variety distinct from the round, peppery radishes dominant in other European traditions. This Italian legacy speaks to a long history of cultivation within specific communities and agricultural regions, where local farmers selected and saved seeds from plants that thrived in their soil and climate. The variety's survival into the modern seed-saving movement reflects the dedication of gardeners and seed companies committed to preserving open-pollinated varieties that carry both agricultural and cultural heritage. Today, Fire Candle remains a testament to the value of maintaining diverse, region-specific crop genetics rather than relying solely on modern hybrids.”
