SunFill Green F1 sunflowers offer a distinctive addition to floral bouquets with their unique appearance resembling artichokes when harvested at the pre-bloom stage. This daylength neutral, single stem variety emphasizes the calyx and disk rather than petals, which are short and subtle. It is bred to be male sterile, producing clean, pollen-free flower heads favored by florists and wholesalers.
Ideal for high density plantings, the single stem SunFill Green F1 grows tall stems, while branching types produce multiple shorter stems requiring more spacing. This variety captures the essence of summer with its bright, clean flowers, making it a standout choice for commercial flower growers seeking novel sunflower varieties.
