Zinnia California Giant Mix Seeds

Zinnia California Giant Mix is a bold and colourful annual flower variety producing large, eye-catching blooms in a vibrant mix of colours. The flowers can reach around 4–5 inches across and appear in shades of cherry, orange, pink, purple, scarlet, and yellow.

This variety grows on strong plants reaching approximately 100cm, making it a great choice for flower borders, cottage gardens, cutting gardens, and summer displays. Zinnias are easy to grow and provide long-lasting colour through the warmer months.

For best results, grow in a sunny position with well-drained soil. Pinching young plants can encourage bushier growth, while removing faded flowers helps extend the flowering season.
