White Welsh Perennial Onion Plants

White Welsh Perennial Onion Plants (5 Plants)

If you’re looking for an onion that keeps producing year after year with almost no fuss, the White Welsh Perennial Onion is a must-have for your garden. These hardy perennial onions don’t form large bulbs like traditional onions — instead, they continuously grow fresh green onion tops that can be harvested almost year-round. Plant them once and enjoy a never-ending supply of delicious scallion-style onions for years to come!

A “Plant It Once” Perennial Onion

White Welsh Perennial Onions (Allium fistulosum) are famous for their ability to multiply and return bigger every season. A single plant will gradually form a thick bunch of 8-10 plants, giving you more harvests every year. Once established, these perennial onions will continue growing indefinitely with very little maintenance.

Harvest the tender green tops anytime for salads, soups, stir-fries, baked potatoes, omelets, and more. You can also pull entire side shoots from the bunch for fresh scallion onions whenever you need them.

Tough Enough for Any Season

One of the reasons we love White Welsh Perennial Onions so much is their incredible durability. These onions are both cold tolerant and heat tolerant, making them perfect for gardeners across a wide range of climates.

• Survives snow and freezing temperatures
• Handles brutal summer heat with ease
• Continues growing through multiple seasons
• Excellent for low-maintenance edible landscapes

We’ve personally watched these perennial onions endure over 6 inches of snow in winter and scorching summer temperatures without missing a beat.

Endless Green Onion Harvests

Unlike bulbing onions, White Welsh onions are grown primarily for their flavorful green tops. The plants can reach up to 24 inches tall when well-fed and watered, providing a steady supply of fresh onion greens throughout the year.

Because the plants multiply so aggressively, you may eventually need to thin the bunches every 1-2 years if you’re not harvesting regularly. The good news? Every division becomes another onion plant!

Easy to Grow & Easy to Propagate

These perennial onion plants are incredibly beginner-friendly and thrive with minimal care. In late spring and early summer, mature plants will produce attractive seed heads that can be collected and replanted elsewhere in the garden. You can also divide mature clumps and transplant them to quickly expand your onion patch.

Growing Tips for White Welsh Perennial Onions
