Raphanus raphanistrum subs. sativus (26 days) F-1 hybrid. Vibrant scarlet skins with crisp sweet white flesh. Sizing up more slowly than Gloriette, they showed the best field-holding quality in the trial and had the sweetest flavor with a mild tang. I found all ten specimens in the sample acceptable, and nine of them sufficiently uniform to be marketable. Round balls with the faintest tendency toward oval. A higher yielder and stands heat better than any of our open-pollinated selections. Short tops. Too much radish seed so bargain-priced. ⑤

About 1,800-3,200 seeds/oz.
A favorite for children’s gardens because quick and easy to grow with minimal fertility requirements.
Culture: Summer radishes may be sown almost as soon as the ground can be worked. Minimum germination 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 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
Culinary: Parboil the greens and roots separately, then eat them together as very early spring salad. And the pot liquor, mmmm…
Days to maturity are from date of seeding
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
