Our "Bloom or Bust" Promise

Mixed, often admired for its multi-color colouring, is a bulb variety especially well suited to borders.

Iris hollandica ‘Mixed’ is a charming blend of Dutch iris in harmonising tones, chosen for elegant, upright flowers that lend a composed, architectural note to late spring planting schemes. Tuck them through borders for refined colour punctuation, or pot up in generous groups for a clean, modern look on terraces and steps.

With slender stems and a naturally poised silhouette, this mixture is also a lovely choice for the cutting garden—particularly when you’d like a succession of stems that feel effortless rather than over-styled. Where conditions suit, it will also settle in and return, quietly improving year on year.

Where to Plant:

Iris 'Mixed' needs full-sun, partial 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 10-15cm 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.
