RADYAN SunFill Purple F1 Sunflower Seeds with Distinctive Pre-Bloom Appearance

SunFill Purple F1 sunflowers provide a unique floral addition with a pre-bloom stage resembling artichokes. This daylength neutral, single stem variety features short petals that highlight the calyx and disk, creating a distinctive look even when fully bloomed. It is bred to be male sterile, producing pollen-free flower heads that maintain a clean and attractive appearance for florists and wholesalers.

This variety is well-suited for high density plantings to produce tall stems, while branching types yield multiple shorter stems requiring more spacing. SunFill Purple F1 captures the essence of summer with bright, cheery blooms that enhance bouquets and garden displays, making it a favored choice for cut flower production.
