Our "Bloom or Bust" Promise

Strongly contrasting decorative dahlias are ideal for adding definition to late-season borders, where their bold colouring continues right through the warm months.

Dahlia 'Purple Explosion' produces bold decorative blooms in deep purple edged white, creating a crisp, high-contrast effect that stands out from a distance and adds drama to summer planting.

The flowers are full and rounded, held above a strong, bushy plant that provides dependable colour from midsummer until frost and plenty of stems for cutting.

Plant in a sunny, sheltered position after the danger of frost has passed, using fertile, well-drained soil and giving the plant support if conditions are windy.

Keep deadheading and watering through dry spells to maintain flowering, then lift and store the tubers once autumn frosts arrive.

Where to Plant:

Choose a sunny, sheltered position with fertile, moisture-retentive but well-drained soil. Dahlias thrive in warmth and perform best where they receive plenty of light and good air movement.

How to Plant:

Start tubers under cover in spring or plant out once frosts have passed. Set the crown just below the soil surface, spacing plants well so stems have room to develop. Add support early for taller varieties and improve soil with compost before planting.

Aftercare:

Water regularly in dry spells and feed through the growing season to support repeat flowering. Deadhead often to keep new buds coming, and lift tubers after the first frost in colder areas for frost-free winter storage.

I ordered the mixed hyacinth collection and the scent in my garden this April was absolutely heavenly. Every single bulb produced a strong, beautiful flower and the colours were stunning together. A fantastic purchase, I'll be back for more next year!
