Blooms in the first year – no vernalization required

One of the key advantages of the Sweet™ series is that vernalization is not required. Sweet™ White will flower in its first year, without the need for a cold period. For professional growers, this means:

• Year-round production,

• Flexible cultivation planning,

• Ability to respond to seasonal peaks such as Valentine's Day, Mother's Day or Christmas bouquets,

• Reliable, uniform flowering with high yield.

This predictability makes the Sweet™ series ideal for commercial cut flower production, where quality and efficiency are essential.

Pure white – versatile application

The bright white color of Sweet™ White makes this cultivar particularly suitable for:

• Luxury bouquets and arrangements,

• Bridal flowers and romantic decorations,

• Mixed bouquets where a neutral filler is desired,

• Retail and export products that require a fresh, clean appearance.

The flowers are large, lightly fragrant, and richly filled, making them excellent as both a focal point and a filler. The neutral color enhances the impact of other flowers and provides an elegant finishing touch to any arrangement.

Uniform growth and strong stems – designed for professional production

The Sweet™ series is designed for optimal growing performance. Sweet™ White offers:

• Strong, straight stems,

• Uniform height and flowering,

• Large, well-filled flower clusters,

• High percentage of saleable stems,

• Excellent shopping and vase life.

This uniformity makes harvesting efficient and reliable, and the sturdy stems can be safely transported for retail and export.

Plant density and growing conditions

For maximum yield, a planting density of 42 to 64 plants per m² (4 to 6 plants per square foot) is recommended. Sweet™ White performs excellently in:

• Greenhouses, for controlled, year-round production,

• Foil tunnels, ideal for spring and autumn production,

• Open ground, in suitable climatic conditions.

Optimization of growth and yield
