25 days. Taste testers agree – this radish will knock your socks off! It has a delicate, mild and sweet flavor, and is crisp yet tender. Similar in size, round shape, and red exterior/white interior to the standard commercial radish but without the harsh spicy bite. So good that radish haters may just be converted. Radishes are early and provide an exciting bounty during the spring Local Food Gap – seeds can be sown as soon as the soil thaws. Also great for kids and school gardens! Roots are uniform, plants are vigorous but petite … so are perfect for space-constrained gardeners. We love these radishes raw but they are also excellent as a quick salt brined pickle. The entire plant is edible - leaves and roots are good in stir fries and young seed pods are crisp with a little spice. Radishes prefer good soil, cool weather, and plenty of water. Occasionally these radishes have hollow centers which does not affect their eating quality. An 1899 heirloom from Canton, Ohio. We originally received our seeds from Seed Savers Exchange’s Heritage Farm – thanks! NN

Growing Instructions (for USDA Zone 5b):

Radishes prefer cool weather. Direct sow seeds outdoors 3/24 – 6/15. For fall, sow seeds 8/21- 9/7.  Plant seeds ½” deep, 1” apart in rows spaced 8” apart. Days to germination: 3 - 6 (longer in cool soil). Keep seeds and plants consistently moist. Space saving tip: Try interplanting radish seeds with beet seeds. The early radish will mature long before the beet. Use crop rotation to avoid clubroot (all brassicas). If necessary, cover with row cover fabric to protect against flea beetles and cabbage root maggots.




Harvest radishes as soon as they  reach full size. Do not leave them in the ground too long or they will become pithy.



Seed Saving Instructions (for gardeners):

Radishes require vernalization (exposure to cold weather) in order to bolt, flower, and produce seed. Sow “Spring” radish seeds no later than 3/24 - 4/15 so that plants will be exposed to cold spring weather. Radishes are insect pollinated and are cross pollinated – they will cross with all other radishes that are blooming nearby. Isolation distance: ½ mile. Minimum population size: 10-50. Dig radishes and identify best roots for replanting for seed (clip off leaves before replanting). Space 2 - 3 feet apart. Stake plants. Clip seed pods when seeds are fully ripe. Dry process.
