Bloom or Bust Guarantee

Compact bedding dahlias are ideal where you want the long flowering power of dahlias without the extra height, making them especially useful for smaller gardens and pots.

Dahlia 'Hartenaas' brings sugar-pink flowers with pale tips to borders and containers, offering a lighter, more playful look than many large border dahlias.

Its relatively compact habit makes it easy to place in mixed planting, while the plentiful blooms still provide plenty of stems for small arrangements and regular cutting.

Plant into fertile, well-drained soil in a sunny, sheltered position once frosts have passed, and keep the soil evenly moist while plants are establishing.

Remove spent flowers often to keep new buds forming, and lift tubers in autumn in colder regions for winter protection.

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!
