New to North America, this Japanese heirloom is a medium sized, oblong daikon type. The wasabi-green skin and flesh is crisp and succulent, with a strong heat reminiscent of the much-loved Japanese horseradish paste. The flavor is sharp and tear-inducing for lovers of spice. Wasabi radish seeds also make excellent micro-greens, with the spiciness developing early on in its tiny leaves. Radishes can be grown all season but they're easiest when sown March/April and again August through October. Optimal soil temperature: 18-24°C (65-75°F). Seeds should sprout in 5-7 days.
