Bishop of Canterbury Dahlia

Bishop of Canterbury Dahlia (Dahlia 'Bishop of Canterbury')

Bishop of Canterbury Dahlia brings rich plum to magenta-red flowers together with dark dramatic foliage for a look that feels both bold and refined. Its open, peony-flowered blooms add strong summer color while still keeping a lighter, more natural feel than fully double dahlias. This variety is especially useful where you want vivid contrast in mixed borders, cutting gardens, or statement containers. From midsummer into fall, it helps keep the garden colorful, layered, and visually sharp.

Distinctive Features

Bishop of Canterbury Dahlia is prized for its cherry-plum to magenta-red flowers, dark stems, and purple-bronze to near-black foliage. The blooms are open-centered, which gives them a lighter, pollinator-friendly character and allows the darker central eye to show clearly against the vivid petals. Plants typically mature to about 30 to 36 inches tall and around 16 to 24 inches wide, forming a bushy upright clump with strong seasonal presence. Its dark foliage makes this cultivar just as valuable before bloom as it is during peak flowering.

Growing Conditions

• Sun: Plant in full sun for the best flowering, strongest stems, and richest foliage color.
• Soil: Grow in fertile, humusy, well-drained soil with consistent moisture and good organic content.
• Water: Provide regular water during active growth, especially in hot weather, but avoid soggy soil.
• Zones: Hardy in USDA Zones 8 to 11, or lift and store tubers in colder climates after frost.
• Habit: Expect an upright, bushy, tuberous perennial with branching stems and a strong seasonal habit.

Ideal Uses

• Perennial Borders: Use it in sunny mixed borders where the dark foliage can add contrast and depth among greener companions.
• Focal Point: Place it in a prominent bed or large container where the vivid flowers and dark leaves can create a bold seasonal highlight.
• Cutting Gardens: Grow it where the long stems and repeat bloom can be cut regularly for arrangements.
• Containers: Use it in large patio containers where its dramatic foliage and flowers can be enjoyed up close.
• Pollinator Plantings: Include it in sunny borders where the open flower centers can welcome bees and other pollinators.

Low Maintenance Care

• Watering: Keep the soil evenly moist during the growing season to support stronger flowering and healthier foliage.
• Deadheading: Remove spent blooms regularly to encourage continued flowering from summer into fall.
• Staking: Provide light support if needed in windy sites or rich soils where stems may become heavier in bloom.
• Feeding: Apply a balanced fertilizer during active growth, but avoid excessive nitrogen that can reduce flower production.
• Winter Care: In colder climates, lift and store tubers after frost once the foliage has been cut back.

Why Choose Bishop of Canterbury Dahlia?
