Dianthus barbatus Sweet™ Mixture – The most versatile top-class cut flower mix within the Sweet™ series

The Dianthus barbatus Sweet™ Mixture is the colorful heart of the industry-leading Sweet™ series. This series has been recognized for years as the best commercial Dianthus barbatus line for professional cut flower production. The Sweet™ Mixture combines all the characteristics growers rely on: perfect uniformity, first-year flowering, strong stems, large umbels, and colors that perform exceptionally well in all segments of the flower market.

The Sweet™ Mixture brings together all 13 beautiful, vibrant colors from the Sweet™ series—from fresh white to intense red, magenta, bicolor varieties, and soft pastels. This makes the mix an ideal choice for growers who want diversity without sacrificing uniformity and commercial quality.

Flowering in the first year – no vernalization required

One of the key advantages of the Sweet™ series is that vernalization is not required. The plants flower effortlessly the same year they are sown, without a cold period. This creates enormous flexibility in crop planning. Professional growers can produce Sweet™ Mixture year-round, responding to seasonal peaks such as Valentine's Day, Mother's Day, or the spring markets, as well as supplying during quieter periods.

This predictability and independence from natural cold makes the Sweet™ line an excellent choice for modern, year-round cut flower production.

A complete range of colours for every type of bouquet

The Sweet™ Mixture offers the full range of intensely colored Dianthus varieties:

• powerful red and magenta hues,

• soft pastel colors,

• stylish bicolor flowers,

• deep, luxurious shades like Black Cherry,

• fresh and light colours for spring bouquets.

This color mix produces flowers that are perfect for retail bouquets, field bouquets, weddings, luxury arrangements, and export products. The variation creates a vibrant color palette that adds softness, depth, or brightness to any bouquet.

The flowers are large, elegantly shaped and lightly scented, adding extra value for florists and consumers.

Commercial quality standard: uniform, strong and reliable

The Sweet™ series is known for its exceptionally uniform growth habit. This means that all colors, despite their diversity, exhibit virtually the same plant shape, stem height, and flowering time. This gives growers:

• Strong, straight stems,

• Consistent salable lengths,

• Large, sturdy flower clusters,

• A high vase and shop shelf life,

• A reliable percentage of saleable stems per m².

These qualities make the Sweet™ Mixture incredibly suitable for professional cut flower cultivation, both for local markets and for export.

Plant density and growing conditions

For optimal production, a planting density of 42 to 64 plants per m² (4 to 6 plants per square foot) is recommended. The Sweet™ Mixture thrives in:

• Greenhouses – ideal for complete climate control and year-round cultivation

• Foil tunnels – for extra early and extra late in the season

• Open-field cultivation – under mild conditions

For taller stems and stronger plants, early-planted autumn plants, which are overwintered in the greenhouse, are particularly effective. This method ensures a strong root system and results in early, vigorous production with high yields.
