Group 3 Lisianthus

Corelli™ Light Pink belongs to Group 3, which indicates its flowering group.

Lisianthus flowering groups help growers plan successive crops and harvest periods throughout the season. Group 3 varieties are later than Group 1 and Group 2 types and are particularly useful for production during the warmer, higher-light part of the growing season.

For growers producing Lisianthus throughout the season, combining different flowering groups makes it possible to extend the harvest period.

Elegant Light Pink Flowers

The outstanding feature of Corelli™ Light Pink is its large, fully double flowers in a delicate light pink shade.

The softly ruffled petals give the blooms a full, romantic appearance, while the pale pink colour works particularly well for:

Wedding floristry • Bridal bouquets • Romantic arrangements • Pastel colour palettes • Premium cut-flower production

Light Pink combines beautifully with white, cream, blush, champagne, apricot, lavender and fresh green, making it one of the most versatile colours for floral design.

How to Sow Lisianthus Seeds

Lisianthus seeds are extremely small and are supplied as pelleted seeds, making them easier to sow individually.

Sow 1 pelleted seed per cell into a fine, moist and well-drained seed-starting substrate.

Place the pellet directly on the surface and do not bury it, as Lisianthus requires light for germination. Gently press the pellet against the moist substrate to ensure good contact.

After sowing, water carefully so the pellet becomes thoroughly moist and begins to dissolve.

Maintain approximately 18–20°C during germination. Under suitable conditions, germination usually takes approximately 10–14 days.

Do not allow the pellet or substrate to dry out during germination.

Growing the Seedlings

After germination, provide the seedlings with plenty of light and good air circulation.

Lisianthus seedlings develop slowly during their early stages. Keep the substrate evenly moist but never waterlogged.

Avoid excessive heat during the young seedling stage. High temperatures can encourage rosetting, where the plant remains compact at the base rather than developing a normal flowering stem.

Allow approximately 7–9 weeks for seedling production, depending on temperature, light and growing conditions.

When to Transplant

Transplant when the seedlings have developed approximately 4 true leaves and a healthy root system.

This is generally around 50–60 days after sowing, although growth speed varies according to environmental conditions.

Avoid keeping established seedlings in small plug cells for too long. Timely transplanting allows the root system to establish quickly in its final growing position.

Planting & Growing

Plant Corelli™ Light Pink in fertile, well-drained soil in full sun.

For cut-flower production, space plants approximately 12–15 cm apart. Relatively close spacing helps encourage long, upright stems suitable for cutting.

For best growth, provide:

• Plenty of light
• Consistent moisture
• Fertile, well-drained soil
• Good air circulation
• Protection from excessive heat during the young seedling stage

Water regularly after transplanting while the root system establishes. Avoid both prolonged drought and waterlogged soil.

Support netting is recommended for cut-flower production to help keep the long stems straight.

Light & Temperature

Lisianthus requires light for germination, so seeds should remain on the surface rather than being buried.

Good light remains important throughout the growing period, particularly as plants begin producing stems and flower buds.

Avoid prolonged cold conditions during active growth, as low temperatures can significantly slow plant development and stem elongation.

Days to Bloom

Lisianthus is a relatively slow-growing cut flower, and the exact time from sowing to flowering depends strongly on sowing date, temperature, light levels and growing conditions.

For Corelli™ Light Pink, its classification as a Group 3 Lisianthus is more useful for crop planning than one fixed number of days from seed to flower.

Allow approximately:

7–9 weeks for seedling production, followed by the main growing period after transplanting.

For this reason, Lisianthus should be sown well in advance of the desired flowering and harvest period.

Harvesting for Cut Flowers

Harvest stems when the first one or two flowers have opened and several additional buds are well developed.

Cut long stems with clean, sharp secateurs and place them immediately into clean water.

The combination of large double light pink flowers, strong stems and an elegant pastel colour makes Corelli™ Light Pink especially suitable for wedding floristry, bouquets and premium floral arrangements.
