Sweet William Sweet™ Salmon Magic F1 | Dianthus barbatus | Pelleted

Sweet™ Salmon Magic F1 is a premium Sweet William (Dianthus barbatus) bred specifically for professional cut flower production, featuring large, fragrant flower clusters with a beautiful colour-changing effect in warm salmon tones. As the individual florets develop and mature, their colour evolves, creating naturally multi-tonal flower heads with shades of salmon, coral pink and soft warm pink.

The special appeal of Salmon Magic lies in this changing colour palette. Instead of appearing as one flat salmon shade, individual florets can show different tones at the same time, giving each flower cluster exceptional depth, warmth and character.

Strong, straight stems and substantial flower clusters make Sweet™ Salmon Magic F1 an excellent choice for cut flower gardens, seasonal bouquets, wedding floristry and professional flower production.

One of the greatest advantages of the Sweet™ series is its ability to flower in the first year without requiring vernalisation, making it much more flexible to grow than traditional biennial Sweet William.

What Colour is Sweet™ Salmon Magic?

The evolving colour is the defining feature of Sweet™ Salmon Magic F1.

As the individual florets open and mature, their shades gradually change, creating a beautiful multi-tonal salmon effect.

Depending on the stage of flowering, a single flower cluster can display a combination of:

• Warm salmon
• Soft salmon pink
• Coral pink
• Warm rosy pink
• Lighter salmon tones as individual florets mature
• Natural colour variations within the same flower cluster

Because the individual florets open at slightly different times, several shades can be visible simultaneously. This creates a warm, romantic and naturally blended appearance rather than a completely uniform colour.

Salmon Magic is particularly beautiful combined with apricot, peach, blush pink, cream, ivory, dusty rose, burgundy and soft green foliage.

Why is the Sweet™ Series Special?

Traditional Dianthus barbatus is commonly grown as a biennial and may require exposure to cold temperatures before flowering.

The professional Sweet™ F1 series has been bred to flower without vernalisation, allowing growers to obtain flowers during the first growing season.

This provides several important advantages:

• Flowers in the first year
• No vernalisation required
• More predictable crop scheduling
• Professional-quality stems for cutting
• Large, uniform flower clusters
• Excellent performance under cooler growing conditions
• Suitable for greenhouse, high tunnel and outdoor production
• Excellent for succession planting

For cut flower growers, Sweet™ can therefore be incorporated into a planned seasonal cut flower programme without waiting until the second year for flowering.

Pelleted Seeds – Easier & More Precise Sowing

Sweet™ Salmon Magic F1 is supplied as pelleted seed.

Pelleting surrounds the naturally small seed with a uniform coating, making it larger and easier to handle. This is particularly useful when sowing into plug trays, where accurate placement of one seed per cell is desirable.

Advantages of pelleted seed include:

• Easier handling
• More precise sowing
• Convenient one seed per cell sowing
• Excellent for plug production
• Practical for professional and home growers

Important: during germination, the growing medium must remain evenly moist so that the pellet coating can soften and the seed inside can germinate successfully.

Sowing Sweet™ Salmon Magic F1

For the most uniform plants, sow Sweet™ Salmon Magic F1 into plug trays.

Sow one pelleted seed per cell.

Place the pellet onto moist seed-starting substrate and cover lightly. Maintain consistent moisture throughout germination and do not allow the growing medium to dry out.

Sowing Information

• Seeds per cell: 1 pelleted seed
• Sowing: Plug trays or individual cells
• Covering: Cover lightly
• Germination temperature: approximately 18–20°C
• Germination: approximately 3–4 days under optimum conditions
• Plug crop time: approximately 5–6 weeks
• Light: Provide high light after germination
• Growing conditions: Cooler temperatures are preferred after establishment

After germination, gradually cooler conditions help produce compact, strong young plants.

When to Sow?

Because Sweet™ Salmon Magic F1 does not require vernalisation, plants can be started from seed and grown to flower during their first growing season.

For an earlier crop, start seeds indoors or in a heated greenhouse.

February–April: a useful sowing period for spring propagation and first-year flowering in temperate climates.

For very early sowings, sufficient light is important. If natural daylight is limited, supplementary lighting can help produce stronger, more compact young plants.

After germination, grow seedlings in a bright location and gradually provide cooler conditions.

Transplant outdoors once the plants are well established and weather conditions are suitable.

Growing for Cut Flowers

Sweet™ Salmon Magic F1 was developed specifically for high-quality cut flower production.

Choose a sunny position with fertile, well-drained soil. Sweet™ performs particularly well under relatively cool growing conditions.

For strong stems and high-quality flowers:

• Grow in full sun
• Use fertile, well-drained soil
• Maintain consistent moisture without waterlogging
• Provide good air circulation
• Avoid unnecessarily high growing temperatures
• Use flower support netting if required
• Harvest regularly

Sweet™ Salmon Magic can be successfully grown in a greenhouse, high tunnel or outdoors.

High light is beneficial, but excessive heat combined with intense light can result in shorter stems. Relatively cool conditions are preferable when growing for premium-quality cut stems.

Perfect for Cut Flowers & Wedding Floristry

Sweet™ Salmon Magic F1 is particularly valuable for floristry because of its sophisticated warm salmon colour palette.

The numerous small flowers form large, rounded clusters that provide beautiful volume and texture in arrangements. As individual florets mature at different times, the combination of salmon, coral and warm pink shades creates a naturally layered effect.

Salmon Magic is especially beautiful for:

• Romantic garden-style bouquets
• Wedding floristry
• Bridal bouquets
• Seasonal arrangements
• Vintage-inspired floral designs
• Peach and apricot colour palettes
• Late-summer bouquets
• Professional floristry

Its warm salmon tones pair particularly beautifully with apricot, peach, cream, ivory, blush, dusty rose, burgundy, mauve and soft green.

The flowers also bring the characteristic pleasant fragrance of Sweet William to freshly cut arrangements.

First-Year Flowering – No Vernalisation Required

One of the most important characteristics of Sweet™ Salmon Magic F1 is that vernalisation is not required for flowering.

Traditional Sweet William is commonly grown as a biennial, producing vegetative growth during its first season and flowering after exposure to winter cold.

The Sweet™ F1 series has been bred differently.

Plants can flower during their first growing season, providing much greater flexibility for both professional growers and home cutting gardens.

This makes Sweet™ particularly useful for:

• First-year flower production
• Planned harvest schedules
• Succession sowing
• Greenhouse production
• High tunnel production
• Outdoor cutting gardens

When to Harvest

For the best cut flower quality, harvest Sweet™ Salmon Magic F1 when approximately 20–50% of the individual florets in each flower cluster are open.

At this stage, the flower head already displays its characteristic combination of salmon and warm pink tones, while the remaining florets can continue opening after harvest.

For best results:

• Harvest during the cooler part of the day
• Use clean, sharp cutting tools
• Cut stems at the desired length
• Remove foliage that would remain below the water line
• Place stems into clean water immediately after cutting

The main crop can generally be harvested over approximately 2–3 weeks.

Under suitable growing conditions, cutting plants back after the main harvest may encourage a second flush of flowers.
