Description

The Delphinium x belladonna 'Bellamosum' is a variety of larkspur that combines many qualities. With a beautiful stature for a belladonna, it offers fabulous gentian blue flowering, highlighted by a small almost black eye in the heart of each flower. Its flower stems appear in early summer, then again in September if care is taken to remove faded flowers. It also stands out for its increased resistance to mildew and the appetite of slugs which too often disfigure or destroy other larkspur plants. Being perennial and cold-resistant, it will flower again each year in romantic or country-style flowerbeds, with its head in the sun and its feet in fertile and moist soil.

 

The Delphinium belladonna 'Bellamosum' is a plant in the family Ranunculaceae belonging to a group of perennial varieties obtained through the cross-breeding of Delphinium elatum and Delphinium grandiflorum. 'Bellamosum' will reach a height of approximately 1.2m (4ft) when in bloom, under optimal growing conditions. In ordinary garden soil without fertilizer or water, it will reach a height of 70-80cm (28-32in),  without the need for staking when sheltered from the wind. Floral stems emerge from a tuft of large palmate and finely divided leaves, first in June-July, then again in September-October. This variety produces branched and slightly loose spikes, 30cm (12in) long, adorned with small flowers measuring 2 to 5cm (1 to 2in) in diameter, usually single, graceful, and light, with a puckered spur that appears frosty. They are an extraordinary blue, bright, striking, almost electric, enhanced by an iridescent and pearly texture, and an almost black centre. The plant develops from a woody rootstock that plunges vertically into the soil, which must be flexible and deep enough to accommodate it.

 

Delphiniums are highly floriferous perennial plants that always stand out in a garden. Belladonna hybrid delphiniums offer a unique way to appreciate these plants. They bring the joy of consistent and faithful blooming, reliably appearing in the expected locations for several years, eliminating the need for regular use of slug pellets. Their characteristic silhouette always adds volume, height, and a lot of charm to perennial plant beds, with an added brightness. They are also good companions for moss or gallica roses, with which they form charming and romantic compositions. You can also create another beautiful combination with soft orange daylilies, chamomiles, and the baby's breath Rosenschleier. Their long-lasting flowers blend well with peonies, roses, white Arum lilies, scabious, foxgloves...

Note: From March to September, the stems of our delphiniums are pruned short to promote better branching of the stump and achieve optimal rooting. This pruning also prevents the stems from breaking during transportation.

Planting and care

Delphinium belladonna Bellamosum prefers to be planted in full sun and sheltered from strong winds. Plant it in a rich, moist, but well-drained soil. It dislikes heavy and wet soils, as well as poor and dry soils, but tolerates a small amount of limestone. Plant it in autumn or spring, after the last frost. While very easy to grow, be sure to provide regular watering to maintain vegetation and apply liquid fertilizer every two to three weeks during growth. Avoid very windy exposures. Stake when the plant reaches 30cm (12in) in height as the stems are fragile and easily break under the weight of the flowers. Remove faded flowers by cutting the spikes at the level of the small lateral flowering shoots. Cut the entire plant back to ground level in autumn. Leave a minimum of two or three shoots on young plants and five to seven on well-established delphiniums. Remove flower stems as soon as they no longer have flowers for a second flowering in late summer. Slugs are to be monitored (use slug repellents from February). This belladonna species is more resistant to diseases than other Delphinium species and seems less appetizing to slugs and snails.
