Long-lasting Garden Delight

Iris 'Dutch Mixed' is a vibrant perennial bulb from the Iridaceae family, celebrated for its dazzling array of summer blooms. Each bulb produces upright stems topped with elegant flowers in shades of blue, yellow, white, and purple—adding instant impact to any garden.

Why Grow Dutch Iris?

  • Seasonal Colour: Enjoy a burst of colour in early to mid-summer when many spring bulbs have faded.
  • Perfect for Cutting: The sturdy stems and long-lasting blooms make these irises ideal for bouquets and vase displays.
  • Disease Resistant: Dutch Iris are known for their robust nature and ability to withstand common garden pests.

Growing Guide

  • Planting Time: Plant bulbs between September and November for summer flowering.
  • Soil Requirements: Prefers well-drained, moderately fertile soil; avoid waterlogged spots.
  • Sun Exposure: Performs best in full sun but tolerates light shade.
  • Mature Height: Reaches approximately 40–60cm (16–24 inches).
  • Hardiness: Hardy throughout the UK (RHS H5); suitable for USDA zones 6–9.

Caring for Your Irises

  • Watering: Water after planting and during dry spells; avoid overwatering once established.
  • Feeding: Apply a balanced fertiliser in early spring as shoots appear.
  • Aftercare: Allow foliage to die back naturally after flowering—this nourishes next year's blooms.

Garden Design Tips

  • Borders & Beds: Combine with perennials like daylilies or alliums for continuous colour.
  • Pots & Containers: Plant in groups for eye-catching displays on patios or balconies.
  • Cottage Gardens: Mix with classic English garden plants such as foxgloves and delphiniums.

FAQs

  • When is the best time to plant Dutch Iris bulbs?
    The ideal planting window is autumn—September through November—before the first frost arrives.
  • How deep should I plant the bulbs?
    Bury bulbs about 10cm (4 inches) deep with the pointed end facing up, spacing them 8–10cm apart.
  • Do they come back every year?
    Yes! Dutch Iris are hardy perennials that return each summer with proper care and well-drained soil.
