300 Cactus Zinnia Seeds Zinnia elegans Double Bloom Flower Garden

Cactus Zinnia (Zinnia elegans) is a warm-season annual prized for its fully double, quilled blooms in a wide mix of bright colors. The spiky, needle-like petals give the flowers a distinctive cactus form, making them a standout in beds, borders, and cut arrangements. These easy-to-grow plants bloom heavily through summer and into fall, attracting pollinators and adding lasting color to sunny landscapes.

Use Cactus Zinnias in cutting gardens, mass plantings, and mixed borders where their tall, sturdy stems and vivid flowers provide long-lasting garden interest. Blooms are excellent for fresh bouquets, holding well after cutting. Plants perform best in full sun with well-drained soil and benefit from regular deadheading to encourage continued flowering.
