Dianthus barbatus interspec. Amazon™ Neon Duo – Versatile, programmable sweet williams for year-round use

Dianthus barbatus interspec. Amazon™ Neon Duo is an exceptional daisy distinguished by its vibrant bicolor flower clusters and year-round cultivation. Developed specifically for professional cut flower growers, this cultivar offers high yields of marketable stems, making it ideal for both monoculture bunches and as a filler in bouquets. Its strong, straight stems and uniform growth make Amazon™ Neon Duo a reliable choice for consistent, high-quality production.

Versatile cultivation all year round

Amazon™ Neon Duo is a programmable sweet willow that's perfectly suited for various cultivation systems. Whether it's winter greenhouse production or summer production in a controlled greenhouse, this cultivar always performs optimally. A key advantage is that vernalization (a cold period) isn't required for flowering. This simplifies cultivation planning and allows for precise harvest timing, increasing efficiency in professional cultivation.

Ideal for bouquets and monoculture bunches

Thanks to its striking two-tone flowers, Amazon™ Neon Duo is ideal as:

• Filler flower in bouquets: adds a vibrant accent color and creates a full, harmonious look

• Monoculture forests: produces uniform, straight, high-quality stems for commercial production

This versatility means the plant can be used for both individual arrangements and large-scale commercial cultivation.

Optimal plant density and yield

For successful cultivation it is important to maintain the correct planting distances:

• Unpruned crop: 30–40 plants/m² (3–4 plants/ft²)

• Pruned crop: 15 plants/m² (1.5 plants/ft²)

At this planting density, Amazon™ Neon Duo produces high yields of marketable stems with consistent length, sturdy stems, and robust flower heads. This makes the cultivar ideal for professional cut flower cultivation and harvesting.

Height and growth potential

As a winter greenhouse crop, Amazon™ Neon Duo reaches a height of up to 91 cm (36 inches), with the tallest and sturdiest stems on plants planted in early fall. The sturdy, upright stems and compact flower heads make this sweet william ideal for harvesting, processing, and selling. The controlled climate of a greenhouse or tunnel promotes uniform growth and predictable production.
