Why Grow Zinnias?

Continuous Blooms: Zinnias flower steadily from midsummer until the first frost, adding non-stop color to beds and containers.

Wide Color Range: Available in nearly every shadeâreds, oranges, yellows, pinks, purples, whites, and multicolors.

How to Select the Right Zinnia for Your Garden

Vase Life: Remove most leaves before arranging to prolong freshness; expect blooms to last a week or longer.
Seed Saving: Allow flower heads to fade on the plant until brown, then harvest and store seeds in cool, dry places.

Mixed Bouquets: Combine large and small blooms for dynamic, textured arrangements.

Pollinator Gardens: Integrate with herbs and wildflowers for a wildlife-friendly patch.
