This majestic variety adds drama and elegance to garden landscapes with its commanding presence and rich, regal color. Let's explore the captivating features and maintenance guidelines for cultivating Delphinium 'Black Knight' in your garden oasis.

Characteristics:

• Height: Delphinium 'Black Knight' reaches impressive heights of 4 to 6 feet (120 to 180 cm), making it a standout focal point in any garden setting.
• Spread: The spread of 'Black Knight' typically ranges from 18 to 24 inches (45 to 60 cm), forming dense clumps of lush, deeply lobed foliage that provide a striking contrast to its towering flower spikes.

Maintenance:

Maintaining the beauty and vigor of Delphinium 'Black Knight' requires proper care and attention throughout the growing season. Here are some maintenance tips to help you cultivate this magnificent perennial:

• Sunlight: Plant 'Black Knight' in a location that receives full sun to partial shade. While it thrives in full sun, providing some afternoon shade in hot climates can help protect the delicate blooms from scorching.
• Soil: Ensure well-draining soil with good fertility and organic matter content. Amend heavy clay soil with compost or aged manure to improve drainage and nutrient availability.
• Watering: Keep the soil consistently moist, especially during periods of active growth and flowering. Provide deep, regular watering to ensure the roots receive adequate moisture, but avoid waterlogging, as this can lead to root rot.
• Mulching: Apply a layer of organic mulch, such as shredded bark or compost, around the base of 'Black Knight' to conserve soil moisture, suppress weed growth, and maintain a cool root environment. Mulching also adds nutrients to the soil as it decomposes.
• Fertilization: Feed Delphinium 'Black Knight' with a balanced, slow-release fertilizer in early spring, just as new growth emerges. Repeat applications every 4 to 6 weeks during the growing season to support vigorous growth and abundant flowering.
• Staking: Provide sturdy support, such as stakes or rings, to prevent the tall flower spikes of 'Black Knight' from flopping over in windy conditions or heavy rain. Install supports early in the season to avoid damaging the plant's roots.
• Deadheading: Remove spent flower spikes promptly to encourage continuous blooming and prevent self-seeding. Cut the flower stalks back to the base of the plant once the blooms fade, using clean, sharp pruners.
• Division: Every few years, divide overcrowded clumps of Delphinium 'Black Knight' in early spring or fall to rejuvenate the plants and maintain their vigor. Replant the divided sections in fresh, well-prepared soil enriched with compost.
