What Makes the Flare Series Special?

Flare is a professional spray-type Lisianthus Series with a distinctive flower arrangement that sets it apart from traditional Lisianthus varieties.

Several double flowers develop close together near the top of each stem and open within a relatively short period.

The result is a beautiful natural bouquet effect on every individual stem.

This makes Flare especially valuable for cut flower growers and florists because one stem already provides considerable volume and visual impact in an arrangement.

The full spray effect may even mean that fewer stems are needed to create abundant, luxurious floral designs.

Flare also offers two important advantages for growers:

No pinching required. The plants naturally develop their characteristic top-flowering spray structure.

Reduced sensitivity to rosetting. Flare genetics have been selected for reduced sensitivity to rosette formation, helping to lower production risk.

Elegant White Double Flowers

Flare White I-II F1 produces sophisticated double white flowers with the soft, layered appearance for which Lisianthus is so highly valued in professional floristry.

White Lisianthus is exceptionally versatile. Its neutral colour works beautifully in minimalist monochromatic designs as well as soft pastel, romantic and natural garden-style arrangements.

The combination of white double flowers and Flare’s distinctive spray habit gives the variety a particularly airy yet abundant appearance.

Flare White combines beautifully with:

• blush and soft pink;
• cream and ivory;
• champagne;
• peach and apricot;
• pale yellow;
• lavender and soft lilac;
• green Lisianthus and green flowers;
• eucalyptus and silvery foliage;
• seasonal greenery and delicate filler flowers.

It is an especially beautiful choice for bridal bouquets, wedding arrangements, ceremony flowers, elegant event floristry and romantic garden-style bouquets.

A Valuable White Lisianthus for Wedding Floristry

White Lisianthus is one of the most useful flowers for wedding and event work because of its elegant, rose-like double flowers and excellent compatibility with many different colour palettes.

Flare adds another advantage: its multiple flowers concentrated at the top of each stem create volume naturally.

This makes Flare White particularly attractive for airy bridal bouquets and larger floral installations where a soft, abundant appearance is desired without making the arrangement look heavy.

The pure, neutral appearance of the white flowers also makes it easy to combine this variety with changing seasonal colour palettes.

Professional Spray-Type Cut Flower

Flare White I-II F1 was bred specifically for professional cut flower production.

Plants produce long, strong stems approximately 91–114 cm tall, with several double flowers concentrated toward the top.

Thanks to this distinctive flower structure, Flare can be used as both a focal and secondary flower, providing texture, volume and movement in floral arrangements.

Key advantages include:

• multiple flowers concentrated near the top of every stem;
• flowers open within a relatively short window;
• natural bouquet effect;
• elegant double white flowers;
• long professional-quality stems;
• considerable volume from a single stem;
• reduced sensitivity to rosetting;
• no pinching required.

What Does Group I–II Mean?

The current Flare Series is classified within approximately Group 1.5–2, placing it in the early-to-medium flowering range of professional Lisianthus production.

Lisianthus flowering groups help growers select varieties with different flowering speeds and plan successive harvests throughout the season.

Actual flowering time is influenced by temperature, day length, light intensity and overall growing conditions, so the group should be used as a production-planning guide rather than an exact flowering date.

Excellent Vase Life

Flare White I-II F1 combines its distinctive spray habit with excellent qualities as a professional cut flower.

When harvested and conditioned correctly, stems have an approximate vase life of 10–14 days.

Because several flowers and buds are carried in the upper part of each stem, Flare maintains an abundant decorative appearance while additional buds continue to open.

Sowing & Germination

Flare White I-II F1 is supplied as pelleted seed, making the naturally extremely small Lisianthus seeds much easier to handle and sow accurately.

Use a fine, high-quality seed-starting substrate and moisten it evenly before sowing.

Place 1 pelleted seed per cell on the surface of the growing medium and press it very gently to ensure good contact with the moist substrate.

Do not bury the seeds deeply. Only a very light covering is recommended; a thin layer of fine vermiculite can be used.

• Seeds per Cell: 1
• Seed Form: Pelleted
• Sowing: Surface sow
• Cover: Very lightly
• Germination Temperature: approx. 20–22°C
• Germination: approx. 8–12 days
• Recommended Initial pH: 5.8–6.2
• Plug Crop Time: approx. 8–10 weeks

During germination, keep the growing medium evenly moist but not waterlogged. It is particularly important that the pellet does not dry out after sowing.

Once seedlings emerge, provide plenty of light and good air circulation.

Important Temperature Tip for Young Plants

Although the Flare Series has been selected for reduced sensitivity to rosetting, young Lisianthus plants should still be protected from excessively high temperatures.

After the earliest germination stage, avoid prolonged growing-medium temperatures above approximately 22°C, as excessive heat can encourage rosette formation.

Affected plants may remain compact and fail to develop normal long flowering stems later in the crop.

Tip for first-time growers: Lisianthus seedlings are extremely small and naturally grow very slowly during their first weeks. This is completely normal.

Do not try to accelerate their growth with excessive heat, overwatering or heavy fertilisation. Consistent moisture, good light and moderate temperatures are far more important.

How Long From Seed to Flower?

Lisianthus has a relatively long growing cycle, so it should be sown well in advance of the desired flowering period.

The plug stage takes approximately 8–10 weeks.

After transplanting, approximate finishing times are:

• Summer: 10–12 weeks
• Spring / Autumn: 12–14 weeks
• Winter: 14–18 weeks

This gives an approximate total crop time from seed to bloom of:

• Summer: 18–22 weeks / 126–154 days
• Spring / Autumn: 20–24 weeks / 140–168 days
• Winter: 22–28 weeks / 154–196 days

For most spring-to-autumn production, a useful general estimate is approximately 126–168 days (around 4.5–5.5 months) from sowing to flowering.

Actual flowering time depends on temperature, day length, light intensity and overall growing conditions.

Light & Flowering

Flare Lisianthus is a facultative long-day plant.

Plants can flower under different day lengths, but longer days can accelerate flowering.

High-quality light also supports stronger plants and better-quality cut flower stems.

For small-scale flower growers and home gardeners, the practical rule is simple: provide as much good-quality light as possible while avoiding excessive heat during the early seedling stage.

Growing

Flare White I-II F1 is particularly suitable for production in a greenhouse or high tunnel.

Lisianthus prefers fertile but well-drained soil with consistent moisture. Avoid keeping the root zone continuously waterlogged.

For professional cut flower production, the current recommended planting range is approximately 65–85 plants/m².

For long, straight cut flower stems, a support net is recommended.

Plants grown outdoors in full sun can develop shorter stems than plants grown under protected greenhouse conditions.

No Pinching Required

One of the most practical advantages of the Flare Series is that no pinching is required.

Plants naturally develop their characteristic spray structure, with multiple flowers concentrated toward the top of each stem.

This reduces labour for professional growers while also making the variety particularly attractive for smaller specialty cut flower farms.

Harvesting

Harvest Flare White I-II F1 when the first flower on the stem has fully opened.

Use clean cutting tools and place freshly harvested stems into clean water as quickly as possible.

The remaining flowers and buds concentrated near the top of the stem create the abundant natural bouquet effect characteristic of the Flare Series.
