These zinnias grow tall enough to anchor the back of flower beds or serve as cut-flower powerhouses, reaching up to four feet in ideal conditions. The blend offers the unpredictability and charm of a mixed color palette, so each plant becomes a small surprise garden. Sown directly outdoors after the last frost delivers faster, stockier plants than early indoor starts, a counterintuitive approach that works beautifully for this heat-loving annual.
California Giants Blend Zinnias excel as cut flowers, their sturdy stems and large blooms lasting well in arrangements. The tall growth habit makes them valuable for creating vertical interest in flower beds and borders, while their prolific flowering nature ensures a continuous supply for bouquets throughout the growing season.
No timeline data available yet for this variety.
Start seeds indoors 4 to 6 weeks before your average last frost date. Maintain soil temperatures between 70 and 80 degrees Fahrenheit for reliable germination. Transplant seedlings outdoors only after all danger of frost has passed, as zinnias are frost-tender annuals.
Transplant seedlings outdoors after your average last frost date, when soil has warmed thoroughly. Space plants 12 inches apart to allow for their mature height and promote good air circulation.
Direct sowing is recommended and typically produces superior results. Sow seeds outdoors 1 to 2 weeks after your average last frost date, when soil is warm and all frost danger has passed. Direct-sown zinnias do not benefit from early indoor sowing and actually thrive when given time to establish in warm weather.
