Delphinium 'Delgenius Shelby' – 'Delgenius Shelby' Larkspur

Delphinium 'Delgenius Shelby' reinvents this classic tall perennial by introducing exceptional sturdiness and outstanding branching. Its dense flower spikes bear a profusion of semi-double flowers in a soft lavender-pink, enhanced by a contrasting white bee. Its compact silhouette eliminates the need for staking, allowing this variety to stand proudly in borders from early to midsummer.

• Foliage : Deeply lobed and finely chiseled leaves display a rich dark green shade, forming a vigorous, stocky, and extremely dense basal rosette.
• Blooming / Fruiting / Stems : Multiple sturdy flower stems carry compact, generous spikes packed with pastel lavender-pink semi-double flowers from June to July.
• Light : Requires a full sun location to maximize flower production and ensure the perfect rigidity of its habit.
• Habit : Presents an erect, compact, vigorously branched, and exceptionally stable silhouette.
• Growth : Rapid growth allows it to reach a height of 60 to 75 cm and a spread of 45 to 60 cm at maturity.
• Soil : Thrives in rich, loose, fresh, and adéquately drained soil.
• Temperature : Exhibits excellent hardiness and easily tolerates zone 3 winters.
• Resistances : Offers superior resistance to powdery mildew compared to older varieties and naturally repels White-tailed deer as well as hares and rabbits.

• Types of use : Structures the midground or background of mixed flower beds, animates perennial borders, and integrates beautifully into large containers on the patio. Its solid stems provide excellent, long-lasting cut flowers for bouquets.
• Decorative advantages : Creates a massive visual impact thanks to its multitude of simultaneous flower stalks, while bringing a touch of softness with its pastel coloring and staking-free verticality.

• Watering : Maintain the soil uniformly moist, particularly during hot summer spells. Water directly at the base of the plant to avoid wetting the foliage.
• Fertilization : Incorporate a good amount of compost at planting. Apply a granular perennial fertilizer in early spring to support its generous bloom.
• Pruning : Cut back flower stalks as soon as they fade to stimulate new growth and encourage a second bloom later in the season.
• Planting : Install the plant in spring, respecting a spacing of 50 cm, and ensure you keep the crown at ground level.
• Winter protection : Let accumulated snow serve as a natural insulator. Spread an organic mulch in autumn to protect the crown from freeze-thaw cycles.
