Description
Les Graines de Cosmos Colletta 'Pink-White' permettent de cultiver facilement cette plante annuelle élégante qui illumine les jardins avec ses fleurs semi-doubles délicatement panachées de blanc et de rose. Son port dressé et buissonnant, agrémenté d’un feuillage finement découpé, lui confère une légèreté incomparable. Idéal en massifs, bordures ou grandes potées, il se cultive aisément en sol bien drainé, sous une exposition ensoleillée, où il déploie une floraison généreuse du début de l’été jusqu’aux premières gelées. Peu exigeant et résistant à la sécheresse modérée, il est néanmoins sensible au vent et peut nécessiter un léger tuteurage pour préserver l’élégance de ses longues tiges souples. Cultivé en groupe, il crée un effet de flou romantique et aérien, parfait pour les jardins champêtres ou les compositions naturelles.
Le Cosmos Colletta Pink-White issu du Cosmos bipinnatus, appartient à la famille des Asteracées. Originaire du Mexique, cette espèce est couramment appelée cosmos des jardins ou cosmos bipenné. Le cultivar 'Colletta Pink White' se distingue par ses fleurs semi-doubles aux pétales blancs délicatement striés de rose. La plante présente un port dressé et buissonnant, atteignant généralement une hauteur de 75 cm à 1,25 m en pleine terre, avec une envergure d'environ 60 cm. En culture en pot, les dimensions peuvent être légèrement réduites, variant entre 60 cm et 1 m de hauteur. La croissance est rapide, permettant une floraison abondante quelques mois après le semis. Les tiges, fines et élancées, portent un feuillage finement découpé, de couleur vert moyen. Les feuilles sont caduques, opposées, bipennées, avec des segments filiformes mesurant entre 2 et 5 cm de longueur. Les fleurs, d'un diamètre de 5 à 8 cm, apparaissent de juin à octobre. Elles sont composées de ligules blanches striées de rose, entourant un disque central jaune. La pollinisation est principalement assurée par les insectes butineurs, notamment les abeilles et les papillons. Les fruits sont des akènes allongés, mesurant environ 1 cm de long, de couleur brunâtre à maturité, non comestibles. Semez vos cosmos dans un sol léger, au soleil, arrosez et puis laissez faire la nature. Ce sont des plantes presque inratables !
Le cosmos Colletta Pink-White ponctue les massifs de ses fleurs délicatement striées. Il apporte une touche de lumière et de mouvement aux jardins naturalistes, où il s’entrelace avec la verveine de Buenos Aires. En bordure, il accompagne la légèreté d’un Gaura lindheimeri ‘Whirling Butterflies’, dont les fleurs prolongent son effet aérien. Pour un jeu de couleurs harmonieux, il se marie à la profondeur du Cosmos bipinnatus ‘Rubenza’, aux teintes grenat. En pot sur une terrasse ensoleillée ou en pleine terre dans un jardin champêtre, il insuffle une atmosphère poétique, où la floraison s’étire tout l’été dans un foisonnement gracieux.
Le nom "cosmos" provient du grec ancien "kosmos", signifiant "ordre" ou "harmonie", en référence à l'arrangement symétrique des pétales. Au Mexique, son pays d'origine, le cosmos est souvent associé aux célébrations du "Día de los Muertos" (Jour des Morts), où ses fleurs sont utilisées pour décorer les autels en hommage aux défunts.

Planting and care
Sow 'Colletta Pink-White' Cosmos seeds from March to May, at a depth of 3mm, in fine compost and cover the seeds with a very fine pinch of vermiculite. Place the seed tray in a mini greenhouse at a temperature of 18-25°C or wrap it in a polyethylene bag. Keep the soil moist, but not waterlogged. Light promotes germination, which occurs 7 to 15 days after sowing.
When the seedlings are large enough to handle, transplant them into individual 7cm diameter pots. Grow them in cooler conditions until the young plants are sufficiently developed to be planted outdoors. When all risk of frost has passed, acclimatise the young plants gradually to outdoor conditions over 7 to 10 days. Plant them out in a very sunny position, in moist, well-drained soil, spaced 50cm apart. Pinch out the growing tips on each stem during transplanting to encourage branching of the stems and the production of numerous flowers.
Cosmos prefer soil with a pH between 6 and 8.5, corresponding to the soil of their native habitat, the alkaline regions of Central America. They prefer full sun, but tolerate partial shade. These plants are drought-resistant once established, they are rarely prone to diseases, but can be targeted by aphids. Self-seeding is common, but not always true to type, without becoming invasive.

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).
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 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.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
