Our "Bloom or Bust" Promise

Grand Prix, often admired for its yellow, white, green colouring, is a tuber variety especially well suited to borders.

For a late-summer border with a touch of theatre, Dahlia ‘Grand Prix’ is a superb choice. A robust, bushy variety, it produces bright lemon-yellow, double blooms neatly tipped in white, held above handsome dark green foliage. Flowering from summer until the first frosts, it is equally at home in the border and in a vase.

  • Colour: lemon-yellow with crisp white tips
  • Flower form: double
  • Habit: clump-forming, bushy
  • Use: borders and cut flowers

Where to Plant:

Dahlia 'Grand Prix' needs full-sun and a warm, sheltered position for the best flowering. Plant into fertile, humus-rich soil that drains well, and choose a spot protected from strong winds, especially for taller varieties.

How to Plant:

Plant tuber from February to June once conditions are suitable. Set them at the correct depth for the variety, spacing the recommended spacing for the variety apart where relevant, then firm in gently and water well after planting.

Aftercare:

Water regularly in dry weather and feed every two to three weeks once buds appear. Stake taller stems early and deadhead to keep plants flowering. After flowering, allow foliage to die back naturally before lifting or protecting tuber according to local conditions.

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!
