With its fresh contrast, strong performance and high yield, this variety is a top choice for professional growers looking for something special within the Dianthus range.

Blooms in the first year – no vernalization required

One of the biggest advantages of the Sweet™ series is that the plants do not require vernalization. This means:

• Flowering without a cold period,

• Fast turnaround times,

• Flexible planning,

• Possibility of year-round production.

For commercial growers, this is a valuable cultivation advantage. You can accurately respond to seasonal peaks, market moments, and contracts, without having to rely on winter conditions to trigger flowering.

A luxurious two-tone pattern – a unique visual impact

Sweet™ Purple White Bicolor stands out with its sharp color contrasts and stylish appearance. The combination of:

• a deep purple flower core,

• framed by bright white borders,

• and a strongly defined bicolor pattern,

This makes this cultivar exceptionally attractive to florists, exporters, and high-end retailers. Bicolor varieties sell particularly well in both mixed and monochromatic arrangements and give any bouquet a refined, almost artistic look.

The flowers are large, lightly scented and have excellent colour fastness, meaning they retain their visual impact even after transport and display in the shop.

Uniform growth and strong stems – ideal for cut flower production

Like all varieties in the Sweet™ series, Purple White Bicolor also produces:

• Strong, straight stems,

• Very uniform height and flowering,

• Large, well-filled flower clusters,

• High percentages of saleable stems,

• A long shopping and vase life.

This uniformity makes harvesting more efficient and ensures exceptionally reliable crop results. The sturdy stems are ideally suited for transport and export, where handling stability is paramount.

Recommended planting density and growing conditions

For optimal yield, the standard planting density is used:

Plant density: 42 to 64 plants per m²
(4 to 6 plants per square foot)

Sweet™ Purple White Bicolor performs excellently in:

• Greenhouses – for year-round, predictable production,

• Foil tunnels – ideal for spring and autumn cultivation,

• Open ground – suitable for mild climatic conditions.

Tip for maximum production

A key cultivation point within the Sweet™ series is that the best stem quality and highest yield are obtained from:

• Early planted young plants,

• which are planted out in the fall,

• and then grown in the greenhouse.

This strategy encourages strong root development and results in more long, sturdy stems in the spring.
