Dash is an F1 hybrid bunching onion that bridges two species, combining the best traits of Welsh onions and common bulbing onions into a compact plant ready to harvest in just 50 days from transplants. Hardy across zones 3 to 10, this early-maturing variety handles frost with ease, making it one of the most reliable scallion options for gardeners in cold climates. Its compact growth habit and fast turnaround mean you can succession-plant through spring and fall for continuous harvests.

Dash earns its speed through smart hybrid genetics, delivering tender bunching onions in 50 days when started from transplants. The frost-hardy nature lets northern gardeners plant in early spring or late summer without fear of cold damage, and its compact growth makes it well-suited to both row crops and container growing. Seed catalogs emphasize its early maturity as a defining strength, and it responds particularly well to the traditional Negi-style deep-planting method that produces a longer blanched white portion.
Dash works as a fresh bunching onion for raw preparations, sliced into salads and grain bowls, or cooked gently into stir-fries and soups where its milder onion flavor won't overpower. The tender white and light green portions are ideal for garnishing finished dishes, while the darker green tops can be chopped and added to dishes near the end of cooking.

Sow 6 to 8 seeds per cell in 72-cell trays at the same time you would seed bulbing onions for transplant production. Maintain germination temperatures between 50 and 75 degrees Fahrenheit.
Transplant seedling clusters outdoors 6 to 8 inches apart in rows 18 inches apart for standard production. For Negi-style scallions with a thicker blanched portion, transplant when seedlings are 8 to 18 inches tall and pencil-thick into holes dibbled about 6 inches deep, spaced 6 inches apart with rows 24 inches apart. Only 1 to 2 inches of leaves should extend above the soil surface. Do not firm the soil after transplanting; allow irrigation or rain to fill in the hole naturally.
Harvest when bunches reach usable size by loosening the soil with a fork or underminer, then gently pull or dig out the entire cluster. Wash thoroughly and hydrocool before storage or use.
