Zinnia Oklahoma White delivers prolific, pure-white double and semi-double blooms measuring 1.5 to 2.5 inches—each featuring subtle green-tinted centers that add understated sophistication. This heirloom variety excels in commercial and home settings alike, prized for exceptional vase longevity and notably low susceptibility to powdery mildew, a common zinnia challenge. The robust flower form and disease resistance make it particularly valuable for market growers, wedding florists, and event designers seeking reliable, long-lasting cut flowers with minimal disease pressure. Plants develop into sturdy, productive specimens that generate abundant blooms throughout the season, supporting continuous harvesting for arrangements or garden display. Flowering occurs in approximately 90 days from sowing, with a consistent 70% or higher germination rate. Each 50-seed packet contains Non-GMO, heirloom stock—genetically stable varieties that can be saved and replanted year after year, building seed security and reducing long-term input costs. Seeds arrive in sustainably sourced, reusable, and fully recyclable packaging, aligning environmental responsibility with the practical, value-driven approach serious growers and floral professionals demand.
