Dianthus Sweet Red Pelleted F1

Vibrant Dianthus Sweet Red for Cool Season Cut Flower Production

Introducing the NEW! Dianthus Sweet Red F1, a high-quality conventional pelleted seed variety specifically bred for cool season cut flower production. This robust plant produces impressive 2 to 5-inch rounded clusters of single-petaled, deep red blooms, noted for being slightly lighter and brighter than ‘Sweet Black Cherry’. Ideal for greenhouse and high-tunnel environments, it also performs exceptionally well in open fields.

This F1 hybrid offers reliable first-year flowering and does not require vernalization, blooming approximately 4 weeks earlier than the ‘Amazon’ variety in trials. Expect high-yielding plants with strong, long stems, typically reaching 18 to 36 inches, and fragrant blooms that can last up to 14 days in a vase.
