Dahlia Showstopper Trio Collection

Dahlia Showstopper Trio Collection brings unmatched colour and grandeur to your late-season garden. Dahlias are renowned perennials from the Asteraceae family, prized for their bold, intricate flowers and extended blooming period. This collection features three premium cultivars, each supplied in a generous 3-litre pot for easy establishment and vigorous growth.

Why Choose This Dahlia Collection?

• 'Cafe Au Lait': Soft apricot-pink blooms fading to warm blush cream, ideal for elegant displays.
• 'Mango Madness': Vibrant pink, peach, and apricot tones deliver a lively splash of colour.
• 'Shiloh Noelle': Lavender-pink petals with white edges and a swirling effect add unique texture.

Growth & Performance:
Expect enormous, layered flowers up to 25cm (10in) across on robust stems. Each plant matures to approximately 120cm (48in) tall with a spread of 60cm (24in), making them standout features in borders or containers. These dahlias thrive in full sun and well-drained soil. Their strong stems make them excellent cut flowers—perfect for bouquets or vase arrangements that last indoors.

Planting & Care Guide

• Planting Time: Best planted after the last frost—typically late spring or early summer in the UK.
• Soil: Prefers fertile, well-drained soil; amend heavy clay with compost or grit for improved drainage.
• Light: Full sun is essential for abundant flowering.
• Watering: Keep soil moist but not waterlogged; water deeply during dry spells.
• Feeding: Apply a balanced liquid fertiliser every two weeks during the growing season.
• Maintenance: Deadhead spent blooms regularly to encourage continuous flowering. Stake taller stems if needed.
• Winter Care: In colder regions (below USDA Zone 8), lift tubers after the first frost and store in a frost-free place until spring.

Design Ideas & Companions

• Create dramatic late-summer borders by pairing with Rudbeckia, Salvia, or ornamental grasses.
• Add to patio pots with trailing lobelia or silver-leaved foliage plants for contrast.
• Cut for showstopping vase displays—these dahlias hold their form beautifully indoors.

FAQs

• When is the best time to plant these dahlias?
  The best time is after the risk of frost has passed—late spring through early summer.
• How long will they flower?
  Dahlias bloom from midsummer right through until the first autumn frosts with regular deadheading.
• Do they need special winter care?
  If your area experiences hard frosts, lift and store tubers in a cool, dry place over winter; otherwise, mulch well in milder regions.
