A Rich Historical Heritage

Zinnias carry a fascinating botanical history:

• Discovery in Mexico: The earliest botanical records of zinnias come from the field notes of Spanish botanists Mociño and Sessé, who discovered the wild species growing in southern Mexico in 1789.
• The Namesake: The common name “zinnia” was chosen to honor the German botanist and professor Johann Gottfried Zinn, who was among the very first to cultivate and study the species in Europe.
• Victorian Sentiment: In the Victorian language of flowers, zinnias famously signify “thoughts of an absent friend.” Planting a bulk mix of California Giant zinnia seeds ensures a breathtaking display of every color imaginable to brighten up your garden beds.

Garden Performance and Wildlife Value

California Giant Zinnias are as practical as they are striking:

• Pollinator Magnet: Their broad, flat flower heads provide the perfect landing pad for butterflies, honeybees, and beneficial insects.
• Deer Resistance: While pollinators flock to the blossoms, the foliage possesses natural deer resistance.

Growing and Care Tips

Getting your zinnias off to a fantastic start is straightforward:

1. Direct Sowing: Direct-sow seeds in spring once the soil has warmed up, as zinnias germinate best in warm earth. Plant them just below the surface and keep the soil lightly moist until germination occurs within 7 to 10 days. (Note: Because zinnias have taproots that dislike being disturbed, direct sowing is preferred over starting indoors.)
2. Maintenance and Pruning: Water seedlings regularly until established, avoiding overwatering. Mature plants tolerate occasional dry spells well, though they thrive best in rich soil with regular moisture and light seasonal fertilization. Pinch back young growing stems to encourage a bushier habit, and deadhead spent blossoms to prolong the blooming season.
3. Harvesting Cut Flowers: For stunning indoor bouquets, snip long stems when the flowers have just opened. Strip away any foliage that falls below the waterline and place them immediately in water.
