More information

Rose Picotee III is a cultivar from the Cessna series, developed for cut flowers. The plant offers large, double white flowers delicately edged with pink, borne on long, sturdy stems from July to September. It grows without difficulty, even when conditions are not perfect. They are not very hardy, so they are usually grown as annuals. Sow from January to March under cover for summer flowering, or in August-September in very mild climates, with protection.

Description

Lisianthus F1 ‘Cessna Rose Picotee III’ displays beautiful double white corollas finely edged with pink and boasts excellent vase life. Much sought after for cut flower arrangements, this cultivar also thrives in flower beds or large pots, where it flowers all summer. The Cessna series is renowned for its ease of cultivation as well as its abundant and regular flowering.
The coated seeds are surrounded by a neutral film that gives them volume. They allow more precise sowing, make handling easier, reduce losses and promote more uniform germination.

Botanically, Lisianthus belongs to the Gentianaceae family. Eustoma grandiflorum is a commonly used synonym for Eustoma russellianum. The species, perennial but short-lived, is native to the Great Plains of North America as far as northern Mexico, where it is found in moist prairies, along streams and in sandy-loam plains, often slightly calcareous. In our gardens, it is grown as an annual or biennial, depending on the climate.

‘Cessna Rose Picotee III’ belongs to the Cessna series, a selection of F1 hybrids dedicated to cut flowers. This line produces well-filled double flowers in summer on long, sturdy stems, good for cutting.
The habit of the plants is upright, branched at the top. In the open ground, their height ranges between 70 and 90 cm, sometimes more under glass; in a 20–25 cm diameter pot, expect 40 to 60 cm in height. The stems are sturdy, bearing opposite leaves, ovate to lanceolate, slightly glaucous and waxy. The cup-shaped flowers, with several rows of petals, measure 5 to 7 cm in diameter; in this variety, they are white with a soft pink edge. Flowering takes place from July to September. After flowering, dry capsules form, containing many fine seeds. The root system is relatively fine, taprooted, sensitive to overwatering and repotting: avoid disturbing the root ball.

‘Cessna Rose Picotee III’ can be used in well-tended flower beds, contemporary-style borders and large containers to decorate the patio. In borders, combine its white flowers edged in pink with fine textures and soft shades: consider Pennisetum alopecuroides ‘Hameln’ for the soft spikes, Gaura lindheimeri ‘Whirling Butterflies’ for movement, and the shrubby sage Salvia microphylla ‘Anduus’ to echo the pink tones. A cloud of Gypsophila paniculata ‘Bristol Fairy’ will lighten the whole arrangement.

Planting and care

How to sow coated seeds of Lisianthus F1 Cessna Rose Picotee III: 
Under a bright, heated shelter: January to March for summer flowering (allow 12–15 weeks before planting out). Sowing is possible from December for well-equipped amateurs. Professionals under heated glass: in October-November to advance the season.
In very mild climates, a sowing in August-September can be attempted under protection for early planting out in spring.

Sow on the surface, without covering, in a fine, sterile compost (pH 6.3–6.8) kept uniformly moist but never waterlogged; they need light to germinate. Ideal temperatures: 20–22°C until emergence (10–20 days), under a lid or film to retain moisture, then 18–20°C with good ventilation and 14–16 hours of light.

Water from below, provide a gentle feed (low-dose balanced fertiliser) and prick out into plug plants when the young plants have 2–3 true leaves, handling the plug without breaking the roots. Harden them off for 10 to 14 days (gradually more light and air) before planting out after all risk of frost.
In open ground, choose a plot in full sun with well-drained, fertile soil, deeply loosened; plant at 15–20 cm spacing, mulch to keep moisture, install support netting if the site is exposed to wind, and water regularly at first, then more sparingly once the roots have established. Maintain steady growth with small applications of potassium-rich fertiliser (avoid excess ammoniacal nitrogen), monitor ventilation to limit Botrytis and damping off, and act quickly against aphids and thrips.
In pots, use a container of at least 25–30 cm, with drainage holes, filled with an airy substrate (quality compost + 20–30% perlite or pumice); water when the top 2 cm are dry, allow to drain, and feed every 2–3 weeks at a light dose or with a slow-release fertiliser. Pinching out is not useful for cutting (it delays flowering), but can be tried very early (4–6 pairs of leaves) on pot plants to encourage branching.

Growing temperatures after planting: 16–18°C at night and 18–24°C during the day; avoid heat stress and watering over the flowers.
For cutting, harvest when the first flower is open, or the buds are well coloured; remove the lower leaves, recut the stems and place them quickly in clean water: vase life is excellent if the plant has grown without water stress.
