Zinnia Seeds

Bright, bold, and easy to grow — zinnias are a summer garden favorite known for their endless color and long-lasting blooms. These cheerful annuals thrive in Canadian gardens, attracting bees, butterflies, and other pollinators while adding vivid texture to borders and containers. From soft pastels to vibrant jewel tones, zinnias bring a burst of energy to any outdoor space and make stunning cut flowers for bouquets and arrangements.

How do I grow Zinnias from seed?

In order to grow Zinnias from seed, you need to sow them directly into warm, well-drained soil after the danger of frost has passed. Choose a sunny location with at least 6–8 hours of daily light. Plant seeds about ¼ inch deep and keep the soil evenly moist until seedlings emerge. For earlier blooms, start seeds indoors 4–6 weeks before the last frost and transplant carefully to avoid root disturbance. Zinnias bloom best when regularly deadheaded, encouraging new flowers to form all summer long.
