Botanical Name: Allium fistulosum
Common Names: Spring Onion, Welsh Onion, Bunching Onion, Green Onion, Japanese Bunching Onion
Spring onion (Allium fistulosum) is a versatile, cool-season vegetable grown for its tender green leaves and mild-flavoured white stems. Unlike common bulb onions, this species typically forms clusters of slender stems rather than large, rounded bulbs. It is widely used in salads, soups, stir-fries, and Asian cuisine. Open-pollinated seeds produce plants that can reproduce true to type when grown under suitable conditions and isolated from cross-pollinating varieties.
This easy-to-grow vegetable thrives in full sun to partial shade and prefers fertile, loose, well-drained soil with consistent moisture. Seeds can be sown directly into garden beds or containers, and the plants can be harvested young for tender greens. Regular harvesting encourages continued growth, making spring onions an excellent choice for home gardens and kitchen gardens.
5 Seed Germination Tips

-
Maintain moisture: Keep the soil evenly moist until germination.
-
Provide suitable temperatures: Around 15–25°C is ideal for germination.
-
Allow time to germinate: Seeds generally sprout within 7–14 days under favourable conditions.
Growing note: For saving open-pollinated seeds, grow compatible plants together and prevent unwanted cross-pollination with other flowering Allium varieties.
