Description
La Célosie crête-de-coq ‘Bar Bossa' (Celosia argentea var. cristata) arbore des têtes en forme de crête charnue abricot clair à base vert tendre. Un coloris "Champagne" élégant pour une plante vigoureuse, aux tiges épaisses, sélectionnée pour les professionnels du bouquet. On l'utilise aussi dans les massifs d’été et dans de grandes potées. Sa floraison s'étale de juin jusqu'aux gelées, et elle fournit d'excellentes fleurs séchées.
Cette variété 'Bar Bossa' appartient à la famille des Amaranthacées. Botaniquement, la crête-de-coq correspond à Celosia argentea var. cristata, synonyme de C. cristata ou C. argentea f. cristata. L’espèce C. argentea est indigène d’Afrique tropicale, aujourd’hui largement naturalisée et cultivée dans les régions chaudes du monde. La forme cristée a été maintenue en culture depuis des siècles en Asie.
‘Bar Bossa’ est un cultivar horticole récent issu des programmes de sélection d’Evanthia aux Pays-Bas. Comparée à d’autres célosies de type cristata, la série Bar demande une culture un peu plus longue, mais offre une crête plus large, un port robuste, des tiges extrêmement solides et une très longue tenue en vase ; elle est en outre moins sensible aux thrips. Dans de bonnes conditions, 9 à 13 semaines s'écoulent entre la plantation et la récolte de fleurs coupées. Celle-ci est possible du printemps à l’automne sous abri chauffé.
De croissance rapide, généralement non ramifiée ou peu, cette variété atteint en pleine terre 60 à 80 cm de haut, un peu moins en pot (40–60 cm selon le volume). Son port est dressé, compact, son feuillage elliptique à lancéolé est d'un vert franc. Les inflorescences sont des crêtes épaisses, très veloutées, au socle vert clair virant au crème, puis à l’abricot-pêche en bordure ; chaque crête peut atteindre 10–15 cm de large. La floraison se renouvelle de juin jusqu’aux gelées. Après la floraison, se forment de petites capsules contenant une multitude de graines noires très fines. Cette célosie est gélive ; sa croissance est optimale par temps chaud. On utilise ses fleurs coupées fraîches et séchées. Pour les faire sécher, on les suspend la tête en bas, dans un endroit chaud et sombre.
En Inde, en Birmanie et en Chine, la célosie crête-de-coq est traditionnellement plantée près des temples, et l’espèce C. argentea est aussi un légume-feuille apprécié en Afrique de l’Ouest.
Au jardin, installez ‘Bar Bossa’ dans un massif très ensoleillé ou dans de grandes potées. Espacez les plants de 30–35 cm, plantez-les en sol léger, que vous enrichirez d’un peu de compost ; binez et arrosez régulièrement par temps chaud, en évitant de mouiller les têtes. En vase, mariez ses fleurs à des zinnias comme ‘Queeny Lime Orange’, des dahlias à fleur moyennes ‘Cornel Bronz’, des amarantes plumeuses ‘Hot Biscuits’ ou des cosmos ‘Apricot Lemonade’ par exemple. Elle se combine très bien avec des célosies comme ‘Bar Bora’ (pourpre), ‘Red Ace’ ou la série Act (ex. ‘Act Dara’) pour jouer sur les volumes et les nuances chaudes tout l’été.

Planting and care
Sow 'Bar Bossa' cockscomb Celosia from February to April in a tray, in warm conditions.
Use a fine special sowing compost, sow on the surface as the seeds are photosensitive, press down very lightly, moisten with a fine spray or by capillary action and, if needed, sprinkle with a thin layer of vermiculite.
Maintain a temperature of 22 to 25°C under bright light without direct sun; germination occurs within 7 to 14 days. Transplant at the two to three true leaf stage into pots and continue cultivation at 17 to 20°C, keeping the substrate moist but not waterlogged.
Begin hardening off the young plants ten to fifteen days before planting and avoid temperatures below 15°C.
Plant in open ground in late May or early June, in full sun, in a well-drained and fertile soil with a pH between 6.0 and 6.4, enriched with mature compost.
To obtain long stems for cutting, space the plants 12 to 15 cm apart and do not pinch; allow eight to thirteen weeks of cultivation before the first cuts.
In flower beds, a light pinching of the plants at 15 to 20 cm can encourage branching. Water regularly during warm periods, hoe or mulch to maintain soil moisture, and provide a net or thin stake in windy sites to obtain straight stems.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
