Shunkyo Semi-Long Radish


Shunkyo Semi-Long Radish is an elongated radish with the perfect balance of spicy and sweet flavors. 4-5″ pink radishes with a crisp, white interior. Grows well in warmer conditions. Raphanus sativus. 30 days to maturity.

250 seeds per packet


Shunkyo Semi-Long Radish is an open-pollinated radish variety that produces smooth, pink roots with a crisp, white interior. This variety is great for any backyard gardener or small-scale market farmer, and is particularly popular in Asian markets. It performs better in warmer temperatures than traditional radish varieties. As a result, it can be planted later in spring and earlier in fall.

Shunkyo Semi-Long Radish produces 4-5" long radishes that have the traditional radish spiciness with a sweet kick. In addition to the roots, the greens are delicious as well. This is a popular variety for microgreen production as well as full-maturity radishes.

Radishes perform best when direct seeded with a walk-behind planter like our Hoss Garden Seeder. We recommend using a modified #1 plate or #2 plate with holes drilled to the appropriate size for the seed being used. Seed size can vary from one variety to the next, so seed plate hole size should always be calibrated to fit the seed being used. Radishes perform well when planted on double rows or on a “bed” with several rows planted closely together. This allows for maximization of garden space and the tops will help to shade any new weed development between closely planted rows.

Radishes grow best in cooler weather and should be planted in early spring or fall when temperatures have cooled. They prefer well-drained soil and will tend to split if soil conditions remain saturated for long periods of time. Radishes should be harvested at the ideal size for each variety. If allowed to get too large, they will become pithy and not as palatable. Once harvested, tops should be removed for optimal storage. Radishes with tops removed will store in the fridge for up to two weeks.
