Our "Bloom or Bust" Promise

Cactus dahlias are distinguished by their narrower, pointed petals, which give the flowers a more energetic, spidery outline and a striking texture in garden planting.

Dahlia 'Hollyhill Cotton Candy' is an eye-catching cactus dahlia with frosted pink petals fading to creamy white, creating a light, feathery effect across large summer blooms.

The more pointed, twisted petals give the flowers extra movement and texture, while tall stems make this a standout choice for cutting and for adding height to sunny borders.

Plant in rich, well-drained soil in full sun after frost has passed, and provide sturdy support early so the stems stay upright as the plant fills out.

Deadhead to encourage continued flowering and lift tubers for safe winter storage in colder areas after the first frost blackens the foliage.

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.

The bulbs arrived beautifully packaged and you could just tell they were excellent quality. We had the most wonderful display of daffodils this spring on our patio. Simply stunning. Will definitely be ordering again

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!
