What Makes Survival Garden Seeds Different - non-GMO heirloom seeds

White Grano is a mild white onion with low pungency. Its flavor is versatile and tasty for both eating raw and for use in cooking. The bulbs average 3" in diameter. This short-day variety is slow to bolt and good for short-term storage.

  • Mild Flavor - White Grano onions have a classic taste that is not too pungent. Their neutral flavor and juiciness makes them excellent for both raw uses and for cooking.
  • Short Day Onion - This onion performs well in the Southern and Western regions of North America, especially in Texas. White Grano onions are slow to bolt, which allows them to be stored longer than other short day varieties.

Frequently Asked Questions

What are heirloom seeds?

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.

Where are Survival Garden Seeds sourced?

The majority of our seeds are sourced in the United States, with a few exceptions when the seed is difficult to source domestically. Whenever we do have to source outside of the US, we ensure our seeds are safe to grow, non-GMO varieties that meet our standards for germination and reliability.

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?

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?

Our seeds will generally last for 3-10 years if they are appropriately stored in a cool, dry place. However, we encourage you to grow your survival seeds within a year or two of purchase. This yields the best germination rates possible and also gives you more experience growing survival food now. At the end of the growing season, follow the instructions on the back of each packet for saving seeds for future gardens. These new seeds for survival will be more adapted to thrive in the growing conditions where you are.
