Buying Guide
What to consider before buying giant zinnia seed mixes

- germination rate and seed type: Are you prioritizing high germination, open-pollinated seeds, or heirloom genetics?
- climate compatibility: Do you garden in heat and drought-prone areas, or cooler regions with shorter summers?
- plant spacing: Some varieties need more spacing for air circulation and bloom quality; others tolerate tighter plantings for mass color.
