Sunflower ‘SunFill™ Purple F1’ | Helianthus annuus | Unique Purple-Green Geometric Sunflower for Florists

Helianthus annuus ‘SunFill Purple F1’ is an innovative, pollen-free sunflower variety bred especially for professional cut flower production. Created by American breeder Tom Heaton, this remarkable sunflower highlights the beauty of the flower’s reverse side — featuring ornamental green and purple sepals that wrap around the bloom to form a striking, geometric shape perfect for modern floral design.

The flower heads measure 7–10 cm across and have a strong, structured appearance, making them an excellent textural filler for bouquets and arrangements. Unlike traditional yellow sunflowers, ‘SunFill Purple’ features sculptural green centers that blend into purple tones — a bold, elegant look for contemporary floristry.

This single-stem, pollenless variety grows rapidly and reaches 150–180 cm in height, producing strong, upright stems ideal for cutting. For best results, harvest before the inner petals begin to open to preserve the unique geometric form.
