Territorial Seed Company Starburst Mix Sunflower

Yes, the Starburst Mix is bred to be entirely pollen-free. This makes them an excellent choice for cutting gardens and indoor arrangements, as they won't drop yellow dust on your tables or linens.

You can expect these plants to reach a mature height of 48 to 60 inches. Because they are well-branched, they maintain a robust, bushy habit rather than growing as a single, towering stalk.

While they are ideally suited for garden beds due to their height and branching habit, you could grow them in very large, deep containers. However, ensure the pot is heavy enough to prevent tipping, as these plants can become top-heavy.

These sunflowers require full sun to thrive and produce their best color. Aim for a spot in your garden that receives at least six to eight hours of direct sunlight daily.

For optimal growth, space your seeds 3 to 4 inches apart. Once they are established, you may want to thin them to ensure adequate airflow and space for the plants to branch out.

No, this variety is an annual. It will complete its entire lifecycle—germination, growth, and flowering—within a single growing season and will not return the following year.
