Description

Giant Larskpur 'Blauw Boeket' boasts numerous spikes of single or semi-double flowers in a lovely array of blue shades. The 1.20 m tall plants are well-branched. Annual delphiniums are hardy, easy-to-grow plants that are popular for cutting. The tall flower spikes stand out at the back of summer beds and borders, gorgeous in front of lower-growing perennials. Direct sow in spring in rich, cool soil, in a sunny, sheltered position.

Delphinium 'Blauw Boeket' is one of the many hybrids selected from Field Larkspur (D. consolida), a winter-germinating annual that occurs naturally in sandy or chalky cornfields. Annual delphiniums are hardy, fast-growing plants that form a wide 35-40 cm clump. The leaves are palmately divided or lobed, soft green in colour, topped with 120 cm tall floral stems in summer. From June to September, single or semi-double cup-shaped blooms appear, densely gathered on tall, erect spires. The display a wide array of harmonious blue shades including dark blue, sky blue, pale blue and greyish-white, sometimes highlighted with a touch of white. They are a magnet to foraging insects.

The characteristic silhouette of Delphiniums always brings an elegant fullness, verticality and charm to perennial beds. For a romantic touch, combine them with old roses and Baby's Breath. The long-lasting blooms are particularly suitable for cutting. For dried flower arrangements, hang small bouquets upside down in a dry, well-ventilated place, away from direct sunlight.

Planting and care

Semez directement à l'extérieur les graines du Delphinium Blauw Boeket, d'avril à mai, en plein soleil, sur un sol fertile, léger, bien drainé, bien ameubli au préalable.

Enterrez les graines fines à une profondeur de 6mm dans des petits trous espacées de 30cm. Maintenez le sol humide en arrosant régulièrement, surtout pendant les périodes sèches. La germination prend généralement de 14 à 21 jours. Lorsque les semis sont assez grands pour manipulés, éclaircissez en ne plantant qu'un plant tous les 15 cm.

Pour obtenir une floraison plus précoce, semer les graines de Delphinium d'août à octobre dans des pots de 7,5 cm dans un terreau de bonne qualité maintenu humide. Placez les pots dans une mini- serre ou à l'intérieur d'un sac en plastique à une température de 15-20 ° C jusqu'à la germination. Une fois que les plantules sont développées, installez-les dans un endroit lumineux, mais plus frais. Hiverner les plantes dans un endroit frais, lumineux mais l'abri du gel en les arrosant avec parcimonie. Transplantez-les à l'emplacement définitif au printemps suivant.

Arrosez régulièrement jusqu'à ce que les plants soient pleinement établis. Enterrez des bâtons solides parmi les plantes hautes de 10 cm, ce qui leur permettra de s'élever tout en étant soutenus. Vous pouvez également tuteurer les plantes avec des cannes de bambou. Enlevez régulièrement les fleurs fanées afin d'encourager le renouvellement de la floraison. Les Delphiniums apprécient les emplacements ensoleillés, protégés du vent, ainsi qu'un sol fertile, riche en matières organiques et bien drainé.
