Zinnia Oklahoma Formula Mix Improved is a versatile heirloom blend engineered for consistent, high-volume cut-flower production across diverse color palettes. These non-GMO seeds reliably produce plants reaching 30 to 40 inches tall, generating prolific double and semi-double blooms measuring 1½ to 2½ inches throughout the season. The formula's color diversity allows gardeners and florists to create dynamic arrangements without requiring multiple seed packets, streamlining both planning and cultivation. Flowers demonstrate exceptional vase longevity, remaining fresh and vibrant for extended periods in water. The variety exhibits strong resistance to powdery mildew, a common zinnia challenge, reducing disease pressure and minimizing intervention needs. Seeds germinate at 70% or higher, establishing vigorous plants that bloom within 75 to 90 days from sowing. Oklahoma Formula Mix Improved thrives in full sun with consistent moisture and well-draining soil, rewarding regular deadheading with continuous flowering through frost. The blend's proven performance makes it invaluable for commercial cut-flower operations, wedding work, and home gardeners seeking reliable, abundant blooms. Seeds are sustainably grown and packaged in eco-conscious, recyclable materials that align with environmentally responsible gardening practices.
