Highlights
Ivory Zinnia produces flowers that defy its compact 12, 18 inch stature, sending up blooms so substantial your neighbors will wonder how you grew them in such a small footprint. The Magellan series genetics make this variety exceptionally tough, shrugging off heat and drought stress that would wilt lesser zinnias. It's an F1 hybrid bred for reliability and resilience, combining non-GMO parentage with hybrid vigor that shows in every flower.
Common Uses
Ivory Zinnia is grown primarily as a cut flower and ornamental garden plant. The massive blooms on compact plants make it especially valuable for cutting gardens, where you can harvest armfuls of long-stemmed flowers without the plant taking over a large footprint. It's also well suited to border plantings, container gardens, and mixed flower beds where you want dramatic color without height.

Care Instructions
Start Indoors
Start seeds indoors about one month before your last frost date. Sow seeds on the soil surface or just barely covered, keeping them warm and moist until germination. Once seedlings develop two sets of true leaves, they're ready to harden off and transplant.
Transplant Outdoors
Transplant seedlings to the garden or containers after the last frost has passed and soil has warmed. Space plants 18 inches apart. Harden off seedlings by gradually exposing them to outdoor conditions over 7, 10 days before planting in their final location.
Direct Sow
Zinnias can be direct sown into warm soil after the last frost date, though indoor starting gives earlier blooms.
Pruning
Pinch or deadhead spent flower heads regularly to encourage branching and continuous blooming. Because this is a compact variety, minimal pruning is needed; the plant's naturally bushy growth habit keeps it tidy without intervention.
