Grow one of the sweetest onions available with Walla Walla Onion Seeds from Survival Garden Seeds. As the official state vegetable of Washington, this heirloom long-day variety is known for producing exceptionally sweet, crisp, juicy bulbs. Walla Walla thrives in northern climates and can be planted in fall for large, full-size bulbs or in early spring for smaller but even sweeter harvests.
Washington’s Famous Long-Day Onion:
Walla Walla onions have long been celebrated in the Pacific Northwest for their mild flavor and dependable performance. This yellow onion develops best under long-day summer conditions, making it an excellent fit for northern growers. Fall planting allows bulbs to overwinter and size up to 5–6 inches, while spring planting yields smaller 3-inch bulbs with heightened sweetness.
Exceptionally Sweet, Crisp Flavor:
Walla Walla onions are prized for their juicy texture and naturally sweet flavor. These golden-brown bulbs are ideal for fresh eating, grilling, sautéing, and any dish where mild onion flavor shines. Their sweetness and crisp bite make them a standout choice for home gardeners who value high culinary quality.
Why Customers Love Walla Walla Onion:
- Famous heirloom with outstanding sweetness
- Yellow, juicy bulbs up to 5–6 inches when fall-planted
- Performs best in northern long-day climates
- Crisp texture ideal for fresh and cooked dishes
- Flexible planting options for size and flavor preferences
How to Grow:
Start seeds indoors 8–10 weeks before your planting date or sow directly outdoors in early spring. In mild northern regions, plant in fall to overwinter for larger bulbs. Choose full sun and loose, well-drained soil for best growth. Keep beds evenly moist, thin seedlings for proper spacing, and maintain weed-free conditions. Harvest when bulbs reach full size and tops begin to fall naturally.

Frequently Asked Questions

Heirloom seeds are the types of seeds your grandparents grew. These varieties have been passed down from generation to generation. They’re old reliable open-pollinated varieties that aren’t typically grown commercially. Instead, they have a rich history that predates modern breeding techniques.
You can learn more about open-pollinated, heirloom, and non-GMO seeds in our Survival Garden Training blog.

How do I know my seeds are fresh?
Every seed packet includes a "packed for" date, and we germination test each seed lot before packaging to ensure you receive viable, high-quality seeds that are ready to grow.
Are your seeds treated?
Are your seeds treated?
No, we do not pre-treat our farmer seeds. All of our garden seeds for sale are untreated, open-pollinated, non-GMO, and heirloom varieties. They are kept in temperature-controlled cooler storage until they are packed and shipped to keep them pest and disease-free.
In what zones can I grow your seeds?
In what zones can I grow your seeds?
The seeds in our collections are specifically chosen from varieties that can be successfully grown from Zone 3 to Zone 10 USDA Hardiness Zones. However, individual varieties have specific needs to thrive in different environments. Each seed pack has optimal temperatures for germination and instructions on seed starting. Consult local frost dates to plan your garden and get the most out of your seeds.
What is the shelf life of these gardening seeds?
What is the shelf life of these gardening seeds?
Most seeds remain viable for 3 to 5 years or longer when stored properly. Check your seed packet for specific varieties. For best results, keep your seeds in a cool, dry place away from direct sunlight and moisture. Store them in an airtight container in a consistent temperature environment—a refrigerator or cool basement works well. Proper storage helps maintain germination rates and extends seed life well beyond the packed date.
