California Giants Zinnias are celebrated for their dramatic, large flowers. They can sometimes measure up to five inches across. These flowers grow in a mix of lovely colors. They typically reach two to three feet tall, ideal for a striking display in a garden setting or as cut flowers. These beauties are Mexico natives but are today grown in gardens from USDA hardiness zones 2 to 11.


Plant your Zinnia (California giants) seeds directly in the garden. Wait until the danger of frost has passed. Choose a location with full sunlight to get the best flowering. Sow the seeds about 1/4 inch deep, barely covering them. Space them 12 inches apart. Zinnias prefer moderately fertile but well-drained soil. Make sure to keep up the consistent moisture until the seeds sprout, in 3 to 10 days.


Once established, California Giant Zinnias are easy to care for. They are tolerant to drought and need watering when extremely dry conditions occur. Remove dry blooms regularly to encourage the plant to produce new flowers. To deter pests, water at the base of the plant and ensure they have enough room for growth and airflow.
