Benary's Giant Golden Yellow Zinnia is a premium open-pollinated cultivar that produces stunning 3 to 4 foot tall plants covered in radiant golden yellow blooms from summer straight through fall. Bred for robust vigor and exceptional flower production, this variety earns its reputation as a workhorse cut flower that blooms reliably 75 to 90 days from seed. The full, bushy plants spread to about 2.5 feet wide, creating a dramatic presence in gardens or containers, and they shrug off both heat and drought stress with ease.

Golden blooms the size of dinner plates emerge consistently from midsummer through the first frost, making this variety legendary among florists and home gardeners who prize long-stemmed cutting material. The plants handle neglect better than most zinnias, tolerating drought once established while still rewarding regular watering with denser flower production. Deer leave them untouched, and butterflies and other pollinators flock to the flowers, transforming your garden into a living hive of activity.
These tall zinnias excel as cut flowers, with long sturdy stems that hold up beautifully in arrangements and vases for weeks when properly conditioned. They're equally at home anchoring the back of a sunny border, adding height and color to cottage gardens, and creating dramatic focal points in landscape beds.

Sow seeds indoors 6 to 8 weeks before your last spring frost. Sow seeds at a depth of 1/16 to 1/4 inch and cover them lightly. Maintain soil temperature between 70 and 75 degrees Fahrenheit, ideally using a heat mat, for germination in 5 to 7 days. Transplant seedlings into a 72-cell flat or larger container and avoid allowing plants to become root-bound, as transplant shock can temporarily trigger single blooms in place of the full double flowers. Handle with care during transplanting to minimize root disturbance.
Move hardened-off seedlings outdoors after all danger of spring frost has passed and soil has warmed. Space plants 9 inches apart in their final location. The larger spacing prevents fungal issues by ensuring adequate air circulation around the foliage.
Direct sow seeds outdoors after your last spring frost. Sow seeds 1/4 inch deep into warm, well-prepared soil. This is a recommended method for this variety.
Cut flowers when the blooms are fully open and vibrant golden yellow, selecting stems with at least 2 to 3 sets of leaves below the flower head. Harvest in the early morning for the longest vase life. Make cuts just above a leaf node to encourage branching and more flowers from the same plant.
Deadhead spent flowers regularly to encourage continuous blooming and maintain a compact, bushy habit throughout the growing season.
