Few ingredients can brighten up a dish quite like spring onions—known in many American kitchens as green onions or scallions. Their crisp white bulbs and long green stalks deliver a delicate balance of flavor—somewhere between the sharpness of a regular onion and the freshness of chives.
From topping tacos and salads to starring in stir-fries and soups, spring onions bring both color and zest to your meals. But what makes them truly special is their versatility and ease of growth. Whether you’re a home gardener with a small balcony or a seasoned grower with raised beds, spring onions thrive in almost any U.S. climate.
In this complete guide, we’ll explore everything you need to know—from planting and harvesting to cooking and storing spring onions, along with their impressive health benefits and tips to keep them growing year-round.
1. What Are Spring Onions (and How Are They Different from Green Onions and Scallions)?
In American grocery stores, the terms spring onion, green onion, and scallion are often used interchangeably—but there are subtle differences worth knowing.
- Green onions / scallions: These are harvested early before the bulb forms, offering a mild, sweet flavor.
- Spring onions: Left to mature a little longer, spring onions have a small, rounded bulb with a more developed but still delicate taste.
- Baby onions: If left to grow even further, they develop into regular onions.
In simple terms, spring onions are the “teenagers” of the onion family—mild enough to eat raw, but flavorful enough to cook with.
2. Why Spring Onions Are a Staple in American Cooking
Across the U.S., spring onions are used in countless dishes—from New York bagels with cream cheese and scallions to Southern casseroles, California stir-fries, and Tex-Mex tacos.
Their popularity comes down to three things:
- Versatility: Use both the white and green parts in cooking.
- Flavor balance: Milder than regular onions, ideal for raw or cooked dishes.
- Aesthetic appeal: Adds color and freshness to meals instantly.
Whether you’re sprinkling them on baked potatoes, tossing them in salads, or grilling them whole at a backyard BBQ, spring onions always bring a touch of freshness and flair.

4. How to Grow Spring Onions at Home in the U.S.
The best part about spring onions? They’re one of the easiest vegetables to grow, even for beginners.
When to Plant
- In most U.S. regions, you can plant spring onions in early spring or late summer.
- They tolerate cool weather and can even survive light frosts.
Where to Grow
- Perfect for garden beds, raised planters, or containers.
- Choose a sunny location with at least 6 hours of light per day.
Soil Requirements
- Well-drained, loose, and rich in organic matter.
- Ideal pH: 6.0 to 7.0.
- Mix compost or aged manure before planting to ensure strong growth.
How to Plant
You can start spring onions from seeds, sets (small bulbs), or kitchen scraps:
- Seeds: Sow about ¼ inch deep and 1 inch apart in rows 12 inches apart.
- Bulbs: Plant them with just the tip visible above soil level.
- Kitchen scraps: Place the white root ends in water until they regrow, then transfer to soil.
Watering & Care
Keep soil evenly moist but not waterlogged. Water gently to avoid washing away seeds.
Pro tip: Mulch around plants to retain moisture and reduce weeds.
5. Caring for Your Spring Onions
Spring onions are low-maintenance, but a few good habits ensure a strong harvest.
Sunlight:
Full sun yields the best growth and flavor.
Fertilization:
Feed lightly every few weeks with compost tea or an organic vegetable fertilizer.
Pest Management:
- Thrips and onion maggots can sometimes attack; prevent by rotating crops each season.
- Avoid planting onions where garlic or leeks grew previously.
Thinning:
When plants are 3 inches tall, thin them so they’re spaced 1–2 inches apart. This ensures thicker bulbs and healthier plants.
6. Harvesting Spring Onions
Spring onions grow quickly—usually ready to harvest in 8–10 weeks from sowing.
How to Harvest
- Use a trowel to gently lift the plants from the soil.
- Harvest when the bulbs are about the width of a finger and stalks are firm.
- Cut off the roots and trim the greens as needed.
To enjoy a continuous harvest, plant new seeds or sets every 2–3 weeks through spring and summer.
7. Storing Spring Onions
Proper storage helps you enjoy your homegrown bounty longer.
Refrigeration:
Wrap spring onions in a damp paper towel and store in a perforated plastic bag in the fridge. They’ll stay fresh for up to 10 days.
Freezing:
Chop the onions and freeze them in an airtight bag for use in cooked dishes.
Regrowing:
Place the root ends in a glass of water on your kitchen windowsill. Within days, you’ll see fresh green shoots ready for harvest again—a fun and sustainable kitchen trick!
