Sparkler Radish


Sparkler Radish is an open-pollinated variety with a striking appearance and crisp, clean flavor. Red radishes with white on the bottom third of the bulb. Raphanus sativus. 25 days to maturity.


Sparkler Radish is an open-pollinated radish variety with a crisp, clean flavor and eye-catching appearance. These radish bulbs have a bright-red top that lightly fades to white on the bottom third of the bulb. This stunning coloration makes this a great variety for small-scale market farmers and backyard gardeners. Sparkler radishes are best harvested around 1" in diameter. Plants produce medium-sized tops that allow for close, dense plantings. Bulbs are round to oval in shape. These are great for raw consumption in fresh salads, but also taste great when sautéed with butter.

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.
