Our "Bloom or Bust" Promise

Blue Planet, often admired for its pastel blue with yellow markings colouring, is a bulb variety especially well suited to containers.

Iris 'Blue Planet' (Reticulata) is a small treasure for the late-winter garden—soft, pastel-blue flowers neatly finished with a golden-yellow stripe, held above fine grey-green foliage. Compact and well-mannered, it slips beautifully into pots, gravel gardens and sunny edges, and will also naturalise with quiet ease where drainage is sharp.

Plant in autumn and look forward to a crisp, bright flourish from February to March. For the most refined display, tuck bulbs into a sheltered, sunny spot—especially welcome where winter colour is prized at close quarters near paths, steps and terraces.

  • Perfect for: containers, rockeries & gravel gardens, naturalising
  • Flowering: February–March
  • Character: pastel-blue with yellow markings; charmingly miniature

Where to Plant:

Iris 'Blue Planet' (Reticulata) 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 bulb from September to December once conditions are suitable. Set them at the correct depth for the variety, spacing 5cm 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 bulb 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!
