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

Sweet™ Cherryblossom Magic F1 is a beautiful professional Sweet William (Dianthus barbatus) bred for cut flower production, featuring large flower clusters in an enchanting range of cherry-blossom pink shades. The flowers create a soft, romantic effect, with colour developing and changing as the individual florets mature.

The special attraction of Cherryblossom Magic is its naturally changing colour effect. Individual florets can display different shades at the same time, creating flower heads with a beautiful combination of deeper cherry pink, soft rose and lighter blush-pink tones. As the flowers mature, the colour gradually softens, giving each cluster a multi-tonal appearance.

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

One of the greatest advantages of the Sweet™ series is that it flowers in the first year without requiring vernalisation. Unlike traditional biennial Sweet William, there is no need for plants to experience a prolonged cold period before flowering.

What Makes Cherryblossom Magic Special?

The Magic varieties in the Sweet™ series are especially interesting because of their changing flower colours.

Sweet™ Cherryblossom Magic does not produce a completely uniform single-coloured flower head. Instead, individual florets develop through different shades as they mature, creating a naturally layered colour effect.

The flower clusters combine:

• Cherry-blossom pink
• Deeper cherry-pink tones
• Soft rose pink
• Delicate blush pink
• Lighter pink shades as the flowers mature

Because flowers at different stages can be present in the same cluster, the overall effect is beautifully multi-tonal.

This makes Cherryblossom Magic particularly attractive for romantic and garden-style floral arrangements where subtle colour variation adds depth and texture.

Why is the Sweet™ Series Special?

Traditional Dianthus barbatus is generally grown as a biennial and often requires a cold period before flowering.

The professional Sweet™ F1 series has been bred to flower without vernalisation, allowing plants to produce flowers during their first growing season.

This offers several important advantages:

• First-year flowering
• 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, tunnel and outdoor production
• Excellent for succession planting

For cut flower growers, Sweet™ can therefore be grown much more like a planned cut flower crop without waiting until the second season for flowering.

Pelleted Seeds – Easier & More Precise Sowing

Sweet™ Cherryblossom Magic F1 is supplied as pelleted seed.

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

Advantages of pelleted seed include:

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

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

Sowing Sweet™ Cherryblossom Magic F1

For the most uniform plants, sow Sweet™ Cherryblossom 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.

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

Do not allow the growing medium to dry out while the pelleted seed is germinating.

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

Growing for Cut Flowers

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

Choose a sunny growing position with fertile, well-drained soil. Plants perform 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 flowers regularly

Sweet™ Cherryblossom 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 & Floristry

Sweet™ Cherryblossom Magic F1 is particularly beautiful as a cut flower because of its changing pink colour palette.

Large clusters of small individual flowers create excellent volume and texture, while the combination of cherry pink, rose and blush shades gives bouquets a natural sense of movement and depth.

It is especially beautiful for:

• Romantic garden-style bouquets
• Wedding floristry
• Bridal bouquets
• Pastel flower arrangements
• Cottage-garden designs
• Seasonal mixed bouquets
• Professional floral arrangements

Cherryblossom Magic combines beautifully with white, cream, blush, pale pink, apricot, peach, mauve and soft green flowers and foliage.

Sweet William also brings its characteristic gentle fragrance to freshly cut arrangements.

First-Year Flowering – No Vernalisation Required

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

Traditional Sweet William is commonly treated as a biennial, developing vegetatively during its first season and flowering after exposure to winter cold.

The Sweet™ F1 series has been bred differently.

Plants are capable of flowering during their first growing season, giving both professional growers and home cutting gardeners much greater flexibility.

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 when approximately 20–50% of the individual florets in each flower cluster are open.

At this stage, the flower head already displays its beautiful multi-tonal colour while unopened florets can continue developing 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

Plants can generally be harvested continuously for approximately 2–3 weeks.

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

Sweet™ Cherryblossom Magic – Changing Pink Shades for Beautiful Bouquets

Dianthus barbatus Sweet™ Cherryblossom Magic F1 combines professional cut flower performance with an exceptionally beautiful, changing palette of cherry-blossom pink shades.

As the individual florets mature, deeper cherry-pink tones soften into rose and delicate blush shades, allowing several colours to appear together within the same flower cluster.

Combined with strong stems, fragrant flowers, first-year flowering and no requirement for vernalisation, this makes Cherryblossom Magic an exceptional choice for both professional flower growers and home cutting gardens.

A beautiful Sweet William for anyone looking for romantic, multi-tonal pink flowers with excellent stems for cutting and floristry.
