Description
Le Tournesol ProCut® F1 Plum (ou Helianthus annuus) séduit par ses pétales crème largement lavés de prune qui mettent en valeur son grand disque brun très foncé. Sa tige non ramifiée, de couleur sombre, est très solide. Dépourvue de pollen, la fleur placée dans un vase ne sème pas de "poussière" à la maison. Au jardin, il se cultive aussi bien en massifs qu’en rangs dédiés à la fleur coupée et fleurit tout l'été, 50 à 60 jours après le semis.
L'Helianthus annuus est une plante annuelle de la famille des Asteracées originaire d’Amérique du Nord ; elle y est spontanée dans les prairies, plaines et friches ensoleillées.
'Plum’ (prune) fait partie de la série ProCut®, développée pour la production de fleurs coupées. Cette lignée a été sélectionnée par le généticien américain Dr Tom Heaton ; la diffusion européenne est assurée par Evanthia. La plante adopte un port érigé. En pleine terre, comptez 1,50 à 1,80 m de haut ; en pot profond (au moins 30–40 cm), la hauteur se situe plutôt entre 1,20 et 1,50 m. La tige ne se ramifie pas en l'absence de taille ou de pincement. Elle est robuste, légèrement pubescente et de couleur brun violacé, une coloration naturelle liée à la présence d'anthocyanes. Le feuillage est vert moyen, rêche au toucher, composé de feuilles triangulaires à cordiformes de 10 à 30 cm de long. Le système racinaire développe un pivot puissant qui s’enfonce profondément. Pour cette raison, il est préférable de semer directement en pleine terre, dans un sol meuble, profond et non compacté.
Les capitules de 10 à 15 cm de diamètre portent des ligules crème à base jaune pâle nuancées de prune rosé vers le cœur brun sombre. La floraison a lieu entre juillet et septembre, selon la date du semis.
Dans un potager fleuri ou un massif d’été, semez ProCut® F1 Plum en lignes espacées de 20–30 cm. Son coloris prune et crème se marie très bien avec des teintes sourdes et des verts frais : choisissez le Cosmos ‘Antiquity’ pour ses corolles bourgogne devenant saumon, la Scabiosa atropurpurea ‘Cherry Vanilla Scoop’ pour ses pompons crème/cerise et l’Amarante ‘Coral Fountain’ aux chandelles retombantes couleur corail. L'indispensable touche de vert peut être apportée par la Moluccella laevis 'Bells of Ireland'. Pour habiller le fond du massif, optez pour une graminée pourpre comme le Pennisetum glaucum ‘Purple Majesty’.
Nos conseils bouquets :
Échelonnez les semis toutes les deux semaines de fin mai à début juillet. Coupez les tiges le matin juste après l’ouverture des fleurs. Supprimez les feuilles en partant du bas pour ne conserver que 2 ou 3 feuilles sous la fleur. Chaque jour, changez l’eau du vase.
Helianthus annuus est une plante annuelle de la famille des Astéracées. Le nom Helianthus associe hélios (soleil) et anthos (fleur), tandis qu'annuus rappelle son cycle annuel. Originaire des grandes plaines d’Amérique du Nord, naturalisé ensuite en Europe dès le XVIᵉ siècle, le tournesol a été domestiqué par les peuples autochtones pour l’alimentation et l’huile.

Planting and care
The 'Pro-Cut F1 Plum' sunflower can be sown:
Either in March-April, in pots under cover, to prepare young plants that can be placed in your borders after the last frosts.
Or from April to June, after the frosts, directly in position. In a sunny spot in your garden. To enjoy beautiful fresh flowers throughout the season, we recommend staggering your sowings as much as possible.
Sow your seeds in groups of 2 at a depth of 1 cm and spaced 50 cm apart. After 20 days, remove the weakest shoot to keep only one per location. The strong growth of the sunflower will require regular watering. When the plant has reached about 1.20 m, you can stop watering and let it make do with rainfall, even if it is scarce. Protect your sowings from snail and slug attacks, as they are fond of these young plants.

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).
