Zinnia Seeds – Non-GMO Heirloom

The ultimate cutting flower worth a spot in your garden

Zinnias (Zinnia elegans) are fast, sun-loving annuals beloved for their big, richly colored blooms and their unbeatable performance as cut flowers. They come in a dazzling range of forms and shades, from tall dahlia-flowered giants to compact button types, in every color but true blue. Zinnias thrive in heat, tolerate drought once established, and bloom more the more you pick, making them one of the most rewarding and forgiving flowers in the garden.

How to grow zinnias from seed

Zinnias are quick and easy to start from seed. Sow them about a quarter inch deep in a sunny, well-drained bed after the last frost once the soil has warmed, then thin plants to stand six to eighteen inches apart depending on the variety. Seeds germinate in under a week and plants bloom in roughly 60 to 70 days, and regular cutting or deadheading keeps them flowering until frost. Good spacing and airflow help keep the foliage healthy. For the full step-by-step, see our complete guide to growing zinnias from seed.

How to use zinnias

Zinnias are grown above all for cutting. Their long, sturdy stems and long vase life make them a florist favorite, and the more you cut, the more the plants produce, so a single row can keep bouquets on the table all summer. In the garden their bright blooms are a magnet for butterflies, bees, and hummingbirds, making zinnias a top choice for pollinator borders. They also add fearless, long-lasting color to beds, containers, and the edges of the vegetable patch.

Zinnia and its cheerful annual cousins

If you love zinnias, you will enjoy the other easy, sun-loving cutting annuals they pair with. Try cosmos for airy, daisy-like blooms on tall stems, marigold for warm gold and orange color, or calendula and nasturtium for more pollinator-friendly, edible-petaled flowers.
