Dianthus barbatus interspec. Amazon™ Rose Magic is a striking and vigorous sweet william distinguished by its vibrant rose hues and year-round production. Developed specifically for professional cut flower growers, this cultivar produces high yields of marketable stems, making it ideal for both monoculture bunches and use as a filler in bouquets. Its strong, straight stems and uniform growth make Amazon™ Rose Magic a reliable choice for consistent, high-quality production.

Versatile cultivation all year round

Amazon™ Rose Magic is a programmable sweet william suitable for various cultivation systems. Whether it's winter greenhouse production or summer production in a controlled greenhouse, this cultivar always performs optimally. A major advantage is that vernalization (a cold period) is not required for flowering, simplifying crop planning and allowing harvests to be precisely tailored to market needs.

Ideal for bouquets and monoculture bunches

Thanks to its intense rose-red flowers, Amazon™ Rose Magic is ideal for:

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

• Monoculture forests: produces uniform, straight stems of high quality for commercial harvesting

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 plant density:

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

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

At this planting density, Amazon™ Rose Magic produces high yields of marketable stems with consistent length, sturdy stems, and compact flower heads. This makes the cultivar ideal for professional cut flower production and commercial harvesting.

Height and growth potential

As a winter greenhouse crop, Amazon™ Rose Magic reaches a height of up to 91 cm (36 inches), with the tallest stems and strongest stems on plants planted in early autumn. The strong, upright stems and compact flower clusters make this sweet william perfect for harvesting, processing, and selling. Under controlled greenhouse or tunnel conditions, the plant develops uniform stems and flowers of consistent quality.
