Dianthus Barbarini Formula Mix 1k Syngenta

The ‘Barbarini Formula Mix’ from Syngenta is an F1 hybrid Sweet William that functions exceptionally well in both bedding schemes and as a cut flower. Unlike traditional biennial Sweet Williams, this F1 hybrid flowers reliably in the first year from an early sowing, offering a programmable production schedule. It grows to a semi-tall height of approximately 10–14 inches (25–35 cm), producing strong stems topped with large, dense clusters (umbels) of flowers in a balanced mix of colors including red, pink, white, and bicolors. It thrives in full sun and well-drained soil, making it a reliable and fragrant choice for borders and floral arrangements.
