INTRODUCING CALIFORNIA GIANTS ZINNIA SEEDS

California Giants Zinnias are celebrated for their dramatic, large flowers. They can sometimes measure up to five inches across. These flowers grow in a mix of lovely colors. They typically reach two to three feet tall, ideal for a striking display in a garden setting or as cut flowers. These beauties are Mexico natives but are today grown in gardens from USDA hardiness zones 2 to 11.

PLANTING CALIFORNIA GIANTS ZINNIA SEEDS

Plant your Zinnia (California giants) seeds directly in the garden. Wait until the danger of frost has passed. Choose a location with full sunlight to get the best flowering. Sow the seeds about 1/4 inch deep, barely covering them. Space them 12 inches apart. Zinnias prefer moderately fertile but well-drained soil. Make sure to keep up the consistent moisture until the seeds sprout, in 3 to 10 days.

MAINTAINING CALIFORNIA GIANTS ZINNIA PLANTS

Once established, California Giant Zinnias are easy to care for. They are tolerant to drought and need watering when extremely dry conditions occur. Remove dry blooms regularly to encourage the plant to produce new flowers. To deter pests, water at the base of the plant and ensure they have enough room for growth and airflow.

Order your Zinnia Giants of California mixed colors pack and enjoy the colorful display in your garden. The bees and butterflies will love them! Remember to save their seeds for next season.

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.

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 chemically treated?

No, we do not pre-treat our seeds. All of our garden seeds 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.

Will your seeds grow in my USDA Hardiness zone?

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 garden 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.

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, heirloom varieties that meet our standards for germination and reliability.
