(65 days) Open-pollinated. For some real heat, try a slice of the venerable Black Spanish. Turnip-shaped 4" roots with corklike black exteriors have extremely pungent white flesh that loses some heat when boiled or stir-fried. Listed in Hortus Kewenis, the 1789 catalog of plants growing at Kew Royal Botanical Gardens, England, as having been brought there in 1548. ④

Additional Information
Winter Radishes
About 2,100-2,900 seeds/oz.
Culture: Winter radishes are slower-growing than the quick summer kind. Many grow deeper roots than summer radishes, often cylindrical in shape. Use wire hoops and row cover to keep out flea beetles. Thin to 6" apart. They hold much longer than summer radishes but if they start to bolt, pinch off the tops. Ideal in late September and October from an early August planting, and can be stored for winter in a root cellar like carrots and beets in slightly moistened sand or layered in damp raked leaves.
Radishes
Days to maturity are from date of seeding
Culture: Summer radishes may be sown almost as soon as the ground can be worked. Minimum germination soil temperature 40°, optimal range 55–85°. They emerge rapidly and grow quickly. Sow 1–2" apart, and thin to at least 2" for attractive uniform roots. Use row cover (p. 144) to protect from flea beetles. They develop more pungency in dry heat than in cool moist weather. Ready for harvest at about the size of a quarter and will rapidly get woody if allowed to grow much larger.
Disease: FY: Fusarium Yellows
Note: We cannot ship packets greater than ½ oz. (14 grams) of radishes into the Willamette Valley. The State of Oregon prohibits shipping any commercial quantity of untreated Brassica, Raphanus or Sinapis due to quarantine
