Helianthus annuus 'Sunfinity Double Yellow'

Helianthus annuus ‘Sunfinity Double Yellow’ is a vigorous, branching sunflower variety known for its double-layered, bright yellow blooms with a dark center. Unlike traditional sunflowers, which produce a single large flower, ‘Sunfinity Double Yellow’ continuously produces multiple blooms throughout the season, making it a long-lasting source of color and nectar. This variety is heat-tolerant, resistant to common diseases, and attracts pollinators like bees and butterflies.

Growing Requirements

Light
