Delphinium 'Red Lark'

Delphinium 'Red Lark': A Rare Flame in the Delphinium World

Uncommon and unforgettable, Delphinium 'Red Lark' turns heads with its luminous coral-red to salmon-pink spires—an extraordinary colour break in a genus traditionally dominated by blues and purples. Blooming in early to midsummer, this bold selection brings both vertical structure and unexpected warmth to the perennial border. Its loose, open spikes and dusky, rose-hued tones make it a standout in cottage gardens and contemporary designs alike. With its generous height, pollinator appeal, and sunset-inspired colouring, 'Red Lark' blazes a fresh trail in the delphinium world.

Plant Characteristics:

• Height: 90–120 cm
• Spread: 45–60 cm, forming upright clumps with tall, loosely arranged spikes
• Flower Colour: Coral-red to salmon-pink with soft apricot undertones
• Flowering Period: Early to midsummer; may rebloom with deadheading
• Foliage: Deep green, deeply lobed leaves forming a compact basal mound
• Sunlight Requirements: Full sun to light shade

Uses and Benefits: Delphinium 'Red Lark' brings a unique splash of colour and upright elegance to early summer gardens. Its warm-toned flowers harmonize beautifully with both cool and hot colour palettes, making it highly versatile in design. This cultivar is ideal for back-of-border placement, mixed perennial beds, or cutting gardens. Its early-season bloom provides valuable nectar for bees and butterflies, while its tall spires add rhythm and grace to the planting.

Companion Plants: Pair Delphinium 'Red Lark' with Echinacea 'Adobe Orange', whose glowing orange blooms echo the coral tones while adding vibrant contrast and pollinator power. Add Panicum 'Prairie Fire' behind for upright structure and burgundy-flushed foliage that intensifies through the season, enriching the planting’s fiery palette. At the base, use Sedum 'Lime Zinger', whose succulent, lime-edged leaves provide a cool counterpoint and neat textural balance.

Care Instructions: Plant in full sun in fertile, moisture-retentive, well-drained soil. Stake early to support tall stems and prevent flopping in wind or rain. Water regularly, especially during dry periods, and mulch to conserve moisture. Deadhead after the first bloom to encourage a second flush. Cut back in late fall. Divide every 3–4 years to maintain vigor.

History: Delphinium 'Red Lark' is a relatively recent introduction that has made waves in horticulture for its rare colour range within the genus. Bred for compact height, strong stems, and floriferous display, it is part of a new generation of delphiniums selected for improved garden performance and broader colour diversity. Its warm-toned flowers are a true novelty and a prized addition to both classic and modern garden palettes.

Final Thoughts: With its unusual coral-pink blooms and graceful spires, Delphinium 'Red Lark' offers a refreshing alternative to the cooler tones typically associated with delphiniums. When paired with the fiery tones of Echinacea 'Adobe Orange', the smoky blades of Panicum 'Prairie Fire', and the bright texture of Sedum 'Lime Zinger', it forms a lively, pollinator-rich planting full of seasonal movement and warmth. A bold, beautiful choice for those seeking something truly unique in their summer garden.
