Roxanne Radish reaches an impressive 24-30 inches tall, standing far above typical radish varieties in the garden. This quick-growing cultivar matures in just 25 days, though some sources suggest it can take as long as 72-76 days depending on growing conditions. Thriving in full sun with minimal water needs, Roxanne adapts to slightly acidic to neutral soils (pH 6.0-7.0) and germinates readily in cool spring temperatures of 50-55°F. Space plants a generous 24 inches apart with 8-inch row spacing to accommodate their substantial height.

What sets Roxanne apart is its towering stature in the radish world, reaching heights that dwarf standard varieties while maintaining the classic quick turnaround radishes are famous for. The variety's low water requirements make it particularly valuable for gardeners seeking drought-tolerant crops, while its ability to germinate in cool spring conditions extends the growing season. Beyond the roots, the nutrient-dense tops shouldn't be overlooked, as they pack even more vitamins and minerals than the spicy roots below.
Roxanne serves multiple purposes in the kitchen, from the mildly spicy roots that add crunch and heat to salads and stir-fries, to the nutrient-packed greens that can be sautéed or added fresh to dishes. The roots provide natural digestive benefits and sinus-clearing properties, while their anti-microbial qualities and high vitamin C content make them valuable for immune support. Don't overlook the seed pods either, which develop a crunchy texture and mild radish flavor when harvested green from bolted plants.

Start seeds indoors about 2 months before outdoor nighttime temperatures consistently reach 50-55°F. Sow seeds 1/4 inch deep and 1 inch apart in seed starting mix, maintaining warm conditions of 80-85°F with strong light until ready for transplant. When seedlings reach 2 inches tall, move them to individual deeper containers and maintain at 70-75°F, feeding with half-strength fertilizer every 2 weeks.
Transplant only after nights stay securely above 55°F, spacing plants 2 feet apart in rich, well-prepared soil. Gradually acclimate seedlings to outdoor conditions and transplant only robust plants with well-developed root systems, mulching well after planting.
Direct sow in spring through early summer, or mid-August through mid-September for fall crops. Three grams of seed will sow 7-8 row feet.
Harvest Roxanne while roots are still young and before they begin splitting, as older radishes develop a strong, fibrous texture that's less palatable. Remove the tops before storing the roots, but save them for cooking as they're packed with nutrients. For an extended harvest, allow a few plants to bolt and collect the green seed pods, which offer a crunchy texture with mild radish flavor.
