Dianthus barbatus 'Flora Pearl Mixture' – Ultra-early sweet william mix for professional cultivation and picking gardens

Dianthus barbatus 'Flora Pearl Mixture' is one of the earliest and most uniform sweet william series currently available for professional cut flower growers. This exclusive blend consists of carefully selected colors from the Flora Pearl line, which together create an attractive and elegant palette. Thanks to the combination of early flowering, strong, tall stems, and exceptional quality, this mix is ​​ideal for greenhouse cultivation, cut flower gardens, and any project where reliability and earliness are paramount.

Earliest series on the market – 4–7 days earlier than Etournelle

The Flora Pearl series is known for its exceptional earliness, and this Mixture is no exception. The variety blooms 4 to 7 days earlier than the Etournelle series, which has been the standard in professional Dianthus cultivation for years. This early flowering is a major advantage for growers seeking:

• A flying start to the season

• Faster market access

• Better price moments

• Tight planning in continuity and harvest cycles

For greenhouse growers, this extra early flowering means immediate returns: the plants come into production faster and deliver uniform, ready-to-sell cut flowers at the first market peak.

Strong, tall stems – ideal for cut flower cultivation

One of the most valued qualities of the Flora Pearl Mixture is its excellent stem quality. The stems are:

• Tall and straight, which makes for graceful bunches and bouquets

• Extremely strong, preventing buckling

• Perfectly uniform, essential for professional packaging and sales channels

The flower clusters are composed of numerous small flowers in a blend of complementary hues—from soft pastels to deeper colors—giving bouquets a rich, natural look. This mix is ​​beloved by florists for its versatility and luxurious look.

Particularly suitable for cultivation under glass

The Flora Pearl Mixture performs exceptionally well when grown under glass, where the benefits of controlled growing conditions are fully realized. Under glass, the plant develops:

• Higher stems than with outdoor cultivation

• Completely uniform growth and flowering

• Maximum control of early production

• High-quality flower clusters with sleek, compact shapes

Professional cut flower growers benefit from predictability, speed and consistency—three crucial factors in commercial flower production.

Blooms after overwintering – sow in late summer

As is typical for Dianthus barbatus cultivars in cut flower cultivation, the Flora Pearl Mixture also blooms after an overwintering period. Therefore, the right time for sowing is essential.

Cultivation advice:

• Sowing: July – September

• Cultivation: late summer and autumn, keep moderately moist

• Wintering: cool, light and sheltered

• Flowering: very early spring to summer

During overwintering, the plant develops a strong root system and a compact base. As soon as the days lengthen, the plant quickly bolts, and abundant, early flowering follows.

Applications and ornamental value

Although the Flora Pearl Mixture is primarily designed for professional cultivation, it is also very attractive for private gardens and cut flower gardens:

• Pick-your-own gardens: uniform growth and long vase life

• Borders: a colorful, romantic look

• Cottage gardens: fits perfectly in a rural, relaxed style

• Greenhouses: compact, strong growth and reliable results

The mix of flower colours adds variety and vibrancy to any flower arrangement or garden design.
