Description

Delphinium consolida DelQis 'Dark Blue Edge' is part of a series of annual larkspur plants selected for their magnificent, harmonious, and sturdy flower spikes, where large double flowers are tightly packed. 'Dark Blue Edge' quickly forms a dense plant that offers frilly, edged, and streaked blue-purple flowers in the year of sowing. Majestic at the back of borders, this delphinium provides excellent blooms for bouquets. The annual Larkspur is easy to grow, even in limestone soil, and can be sown directly in the ground, in borders or beds, in rich and moist soil.

 

Delphinium DelQis 'Dark Blue Edge' is one of the many hybrids obtained by cross-breeding the Consolida Larkspur, in Latin Delphinium consolida, an annual plant with a preference for winter germination that grows in cereal crops on clay-limestone soil. The DelQis 'Dark Blue Edge' selection is a hardy annual plant in its juvenile state, with rapid growth. It forms a wide clump of 35 to 40cm (14 to 16in), with finely divided palmate foliage, tender green, from which robust and branched flower spikes of 90cm (35in) to 1m (3ft) in height emerge in spring or summer depending on the climate, very uniform. Flowering occurs from June to September and is highly visited by pollinating insects. The double flowers, with spurs, are cup-shaped and gathered on tall, densely packed spikes. The flowering is followed by the formation of numerous seeds that will easily germinate in the garden. The plant develops from a woody rhizome that extends vertically into the soil.

 

The characteristic silhouette of Delphiniums always adds volume, verticality, and charm to perennial plant borders. The DelQis 'Dark Blue Edge' selection allows for the quick creation of a theatrical yet elegant display by sowing directly in the ground. Delphiniums are good companions for roses, with which they create charming and romantic compositions. You can also create another beautiful combination in a white garden with paniculate baby's breath, Crambe cordifolia, or Gillenia trifoliata. This variety is particularly suitable for making bouquets, as its flowers are long-lasting in a vase and can even be dried. To do this, cut open flowers into small bouquets, hang them upside down, store them away from the sun in a dry and well-ventilated place. Create a stunning bouquet with delphiniums and gladioli.

Planting and care

Sow the seeds of Delphinium DelQis 'Dark Blue Edge' directly outdoors from April to May, in full sun, on a fertile, light, well-drained soil, previously well-prepared. In mild climates, sowing can be done in late summer or early autumn (the young plants are relatively hardy), which allows for earlier flowering in the season.

Bury the fine seeds to a depth of 6mm in small holes spaced 30cm (12in) apart. Keep the soil moist by watering regularly, especially during dry periods. Germination usually takes 14 to 21 days. When the seedlings are large enough to handle, thin them out by planting only one plant every 15cm (6in).

To achieve earlier flowering, sow Delphinium seeds from August to October in 7.5cm (3in) pots filled with quality compost kept moist. Place the pots in a mini-greenhouse or inside a plastic bag at a temperature of 15-20°C (59-68°F) until germination. Once the seedlings have developed, move them to a bright, but cooler location. Overwinter the plants in a cool, bright place, protected from frost, by watering them sparingly. Transplant them to their final location in the following spring.

Water regularly until the plants are fully established. Insert sturdy stakes among the plants when they reach 10cm (4in) in height, which will allow them to grow while being supported. You can also stake the plants with bamboo canes. Regularly remove faded flowers to encourage renewed flowering. Delphiniums thrive in sunny locations, protected from the wind, as well as in fertile soil, rich in organic matter and well-drained.
