Professional Campana F1 Cut Flower Series

Campana is a high-quality professional series bred specifically for cut flower production.

One of its most important characteristics is 100% top-flowering, with flowers developing attractively towards the upper part of the stem.

The Campana series is valued for:

• Strong, upright stems
• Good-quality foliage
• Excellent uniformity
• Well-matched flowering time and habit
• 100% top-flowering
• Professional cut flower quality
• Suitability for both Summer and Winter production
• Relatively low-energy production

Campana White is an excellent choice for professional growers as well as gardeners who want to grow florist-quality flowers for cutting at home.

Sowing & Germination

Campana White F1 is supplied as pelleted seed, making the naturally tiny Campanula seeds much easier to handle and sow accurately.

Sow 1 pelleted seed per cell onto the surface of a fine, moist seed-starting substrate.

Do not cover the seeds, as light is beneficial for germination.

• Sowing: Surface sow
• Seeds per cell: 1
• Cover seed: No
• Germination temperature: approximately 20–22°C
• Germination: approximately 4–5 days
• Plug crop time: approximately 7–8 weeks

Keep the substrate evenly moist but not waterlogged during germination. Pelleted seeds should not be allowed to dry out after sowing.

After germination, grow the young plants at slightly cooler temperatures of approximately 16–18°C to encourage compact, strong development.

How Long From Seed to Flower?

Allow approximately 7–8 weeks for plug production, followed by approximately 10–14 weeks from transplanting to flowering.

The total growing time is therefore approximately:

17–22 weeks, or around 119–154 days from seed to flower.

Flowering time can vary depending on temperature, light levels, daylength and growing conditions.

Important – Daylength

Campana is sensitive to daylength, and managing light correctly helps produce long, high-quality stems for cutting.

Young plants should first be allowed to establish good vegetative growth and develop strong stems. Longer days later encourage flower initiation.

In professional production, Campana is initially grown under shorter days, followed by daylengths longer than approximately 14 hours to encourage flowering.

For smaller growers, the most important point is to avoid encouraging flowering too early. Premature flower initiation can result in shorter stems.

Campana is therefore particularly well suited to greenhouse or tunnel production, where growing conditions can be managed more easily.

Growing

Plant Campana White in fertile, well-drained soil in a sunny position.

Maintain consistent moisture throughout active growth, particularly while plants are developing their long flowering stems.

Avoid repeated drying, as dry conditions can encourage earlier flowering and shorter stems. At the same time, avoid waterlogged soil, which can weaken the root system and stems.

For professional cut flower production, space plants approximately 10–13 cm apart, or around 64–80 plants per m².

Feeding

Regular nutrition helps Campana produce long, strong and high-quality stems.

Use a balanced complete fertiliser containing micronutrients during active growth.

Consistent feeding and moisture are more important than very heavy fertilisation. Water or nutrient stress can encourage premature flowering and reduce stem length.

Support

Because Campana produces long flowering stems, a support net is recommended when growing it for cut flowers.

Support helps keep stems straight and protects them from bending as the flowers develop.

Harvesting

Harvest Campana when approximately 2–3 flowers on the stem are fully open.

Place freshly cut stems into clean, cool water as soon as possible.

With good post-harvest care, Campana can provide a vase life of up to approximately 10 days.
