Description
Le Tournesol Helianthus annuus F1 ProCut® 'White Lite’ offre de grandes corolles ivoire autour d’un disque doré-vert, très recherchées pour les bouquets de mariage. Hybride F1 à tige unique et fleurs dépourvues de pollen, il produit des hampes droites, solides et homogènes. Cette variété, destinée aux professionnels de la fleur coupée, se cultive sans difficulté dans le jardin d'un amateur.
Cette plante annuelle de la famille Asteracées est une sélection horticole de l’espèce botanique Helianthus annuus. Cette dernière est originaire d’Amérique du Nord, des Grandes Plaines aux régions du Sud et du Mexique, où elle colonise prairies ouvertes et terrains perturbés ; elle a été domestiquée par les peuples amérindiens puis largement diffusée.
Le cultivar ‘ProCut® White Lite’ a été sélectionné par Evanthia aux Pays-Bas au sein de la série ProCut®, dédiée à la fleur coupée. Les cultivars ProCut® offrent tous une floraison sans pollen, une tige unique bien droite et les plantes issues de semis sont uniformes.
La plante présente un port dressé et une croissance rapide : on compte 8 à 11 semaines du semis à la floraison. En pleine terre, ce tournesol atteint 1,50 m à 1,80 m de haut ; il sera plus compact en pot, entre 1,20 m et 1,50 m selon le volume. Les fleurs mesurent 10 à 15 cm de diamètre. Elles se composent de "pétales" ou ligules crème à ivoire entourant un disque central vert doré. Les floraisons s’échelonnent de juillet à septembre selon la date du semis. La tenue en vase est de 7 à 10 jours. Les feuilles sont grandes, ovales à cordiformes, vert moyen, légèrement rugueuses. La tige est robuste, striée, pubescente. Le système racinaire développe une racine pivotante profonde assurant une bonne tolérance aux périodes sèches une fois la plante bien installée.
‘ProCut® White Lite’ a toute sa place dans un jardin de fleurs à couper, en rangs au potager ou en grandes taches dans un massif ensoleillé. Dans un bouquet blanc, mariez-le à des Cosmos ‘Sensation Purity’, des Ammi visnaga 'Casablanca', des Echinacées purpurea 'Virgin', ou encore à des Dahlias ‘Lady Liberty’. Ajoutez quelques épis de Queue-de-lièvre 'Bunny Tails' pour alléger l'ensemble. Si vous le cultivez en pot, choisissez un contenant profond, de 40 cm de diamètre au minimum, réduisez la densité de plantation et tuteurez vos plants si nécessaire.
Nos conseils bouquets :
Échelonnez les semis toutes les deux semaines de 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.
Le tournesol, domestiqué il y a plus de 4 000 ans, servait à fournir graines, huile et teinture ; sa symbolique solaire lui a valu d’être diffusé en Europe dès le XVIᵉ siècle.

Planting and care
The Sunflower Pro-Cut F1 'White Lite' can be sown:
Either in March-April, in pots under cover, to prepare young plants that can be planted out in your borders after the last frosts.
Or from April-May to July, 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 vigorous 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. Also watch out for birds when the plants emerge and for aphid appearance.
Do not pinch ProCut® (single stem). Stake if the site is windy; mulch to retain moisture and limit weeds.
In a pot, allow 20–30 litres of well-draining substrate in a container 30–40 cm wide and provide regular watering. Crop rotation and watering at the base of the plants help to limit collar diseases.

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).
