Eustoma grandiflorum Flare Deep Rose I-II F1 | Lisianthus | Pelleted Seeds

Professional spray-type Lisianthus with richly double, deep rose-pink flowers clustered at the top of long, strong stems – creating a naturally abundant bouquet effect on every stem. No pinching required.

Eustoma grandiflorum Flare Deep Rose I-II F1 is a professional cut flower Lisianthus from the exceptional Flare F1 Series, specially bred for its distinctive spray-type, top-flowering habit.

Unlike traditional Lisianthus, Flare produces several double flowers concentrated near the top of each stem. The flowers open within a relatively short window, giving every harvested stem the appearance of a naturally arranged miniature bouquet.

Flare Deep Rose I-II stands out with its beautiful deep, rich rose-pink flowers. The saturated colour gives bouquets depth and impact while remaining elegant enough for romantic and wedding floristry.

Another important advantage of the Flare Series is its reduced sensitivity to rosetting, helping to lower production risk when growing Lisianthus.

What Makes the Flare Series Special?

Flare has been bred as a professional spray-type Lisianthus Series with a flowering habit that is noticeably different from traditional Lisianthus.

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 stem.

This characteristic is especially valuable for cut flower growers and florists because a single Flare stem provides considerably more visual volume in a bouquet or floral arrangement.

The full spray effect can even mean that fewer stems are needed to create a lush, abundant arrangement.

Flare also offers two important production advantages:

No pinching required. Plants naturally develop the characteristic concentration of flowers at the top of each stem.

Reduced sensitivity to rosetting. The Flare Series has been specially selected to reduce the risk of rosetting and provide more reliable production.

Rich Deep Rose Flowers

Flare Deep Rose I-II F1 produces elegant, double flowers in a beautiful deep, saturated rose-pink colour.

The rich rose tone gives this variety a strong floral presence without being overly dark, making it exceptionally versatile for both romantic and contemporary arrangements.

Deep Rose combines beautifully with:

• blush and soft pink;
• white and ivory;
• cream and champagne;
• peach and apricot;
• burgundy and wine tones;
• lavender and soft lilac;
• green Lisianthus and other green flowers;
• eucalyptus and silvery foliage.

It is particularly beautiful for wedding bouquets, romantic arrangements, garden-style bouquets and sophisticated professional floristry.

Professional Spray-Type Cut Flower

Flare Deep Rose I-II F1 has been specially bred for professional cut flower production.

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

Thanks to this distinctive flower structure, Flare can be used both as a focal flower and as a secondary flower that adds volume and fullness to floral arrangements.

Key advantages include:

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

What Does Group I–II Mean?

Flare Deep Rose I-II belongs to the early to medium flowering range of Lisianthus.

Lisianthus flowering groups are used by professional growers to plan varieties with different flowering speeds and create a more continuous harvest throughout the season.

Group I–II varieties are positioned toward the earlier part of the Lisianthus flowering schedule, making Flare Deep Rose particularly useful for extending the beginning of the harvest season.

Actual flowering time will depend on season, temperature, day length, light intensity and growing conditions, so the group should be used as a crop-planning guide rather than an exact flowering date.

Excellent Vase Life

Flare Deep Rose I-II F1 combines its distinctive spray habit with excellent performance as a cut flower.

When harvested and conditioned correctly, flowers have a vase life of approximately 10–14 days.

Because each stem carries several flowers and buds near the top, it maintains a full and decorative appearance while additional flowers continue to open.

Sowing & Germination

Flare Deep Rose 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 substrate and gently press the pellet to ensure good contact with the moist growing medium.

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: Light cover
• Germination Temperature: approx. 20–22°C
• Germination Time: approx. 8–12 days
• Recommended Initial pH: 5.8–6.2
• Plug Crop Time: approx. 8–10 weeks

During germination, keep the substrate evenly moist but never waterlogged. It is particularly important that the seed pellet does not dry out after sowing.

After germination, 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 excessive heat.

Beginning in the early seedling stages, avoid prolonged growing-medium temperatures above approximately 22°C, as excessive heat can encourage rosetting.

Affected plants may remain compact and fail to develop normal long flowering stems after transplanting.

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 much more important.

How Long From Seed to Flower?

Lisianthus has a relatively long crop time, so it is best to start seeds well in advance of the desired flowering period.

The plug stage takes approximately 8–10 weeks.

After transplanting, flowering generally takes approximately:

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

During the main growing season, the total crop time is therefore approximately 18–24 weeks or 126–168 days (about 4.5–5.5 months) from sowing to flowering.

Winter production can extend the total crop time to approximately 154–196 days.

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

Light & Flowering

Flare Lisianthus is a facultative long-day plant.

This means plants can flower under different day lengths, but longer days can encourage faster flowering.

Good light intensity also promotes stronger plants and high-quality cut flower stems.

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

Growing

Flare Deep Rose I-II F1 is particularly well suited to growing in a greenhouse or high tunnel.

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

For professional cut flower production, an approximate planting density is:

• Summer: approx. 84 plants/m²
• Winter: approx. 64 plants/m²

Depending on the season and growing conditions, approximately 65–86 plants/m² can be used.

A support net is recommended to help produce long, straight cut flower stems and is particularly important when growing in tunnels.

Plants grown outdoors in full sun may produce shorter stems than greenhouse-grown plants.

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 several flowers concentrated near the top of each stem.

This reduces labour for professional growers while also making the variety more convenient for smaller cut flower farms.

Harvesting

Harvest Flare Deep Rose I-II F1 when the first flower on the stem is fully open.

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

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