Product Information

Full details

The Thompson and Morgan Iris Metallic Mixture is ideal for gardeners looking to add sophisticated, rich color to their outdoor spaces during late spring and early summer. This 160-bulb collection offers a striking blend of purple, maroon, and yellow blooms, providing excellent versatility for use in borders, garden beds, or patio containers. While these irises are hardy and relatively low-maintenance, they do require consistent access to well-drained soil and plenty of sunlight to thrive, meaning they may not be suitable for heavily shaded or waterlogged areas of the landscape.

FAQs

When is the best time to plant these irises?

These bulbs should be planted in the autumn to allow them to establish roots before the winter dormancy period.

Can I plant these in pots?

Yes, they thrive in containers provided you use a well-draining, loam-based compost.

How deep should I plant them?

Plant the bulbs at a depth equivalent to twice their height.

Are these perennial flowers?

Yes, they are hardy bulbs that will return and bloom each year provided they are cared for correctly.

How far apart should I space them?

For best results, space your bulbs 10cm apart.

Will they grow in the shade?

These irises perform best in sunny spots; they are unlikely to bloom well in deep or constant shade.

Troubleshooting

Poor or non-existent flowering

Check if the planting site receives enough sunlight; iris bulbs require consistent full sun to initiate blooms.

Bulbs rotting in the soil

Ensure the soil is well-drained. If the soil is waterlogged, move the bulbs to a raised bed or a container with improved drainage components.

Weak, leaning stems

This is often a sign of insufficient sunlight, causing the plant to stretch (etiolate) toward light sources.

Pros and Cons

Pros

  • High-impact color contrast
  • Suitable for both ground planting and container gardening
  • Excellent for home-grown cut flowers
  • Hardy variety that returns annually
  • Easy to establish in the correct conditions

Cons

  • Requires full sun for optimal flowering
  • Cannot tolerate poorly drained soil
  • Specific autumn planting window required
  • Height is limited to 50cm, which may be too short for the back of deep borders

Setup, Compatibility & Care

For the best results, plant these bulbs in autumn at a depth equal to twice the height of the bulb. Space each bulb approximately 10cm apart to allow for adequate airflow and root expansion.

  • Soil Quality: Prioritize well-drained soil. If you have heavy clay, add grit or sand to improve drainage before planting.
  • Sunlight: Ensure the site receives full sun for the majority of the day to prevent weak stems and sparse flowering.
  • Maintenance: During the growing season, keep the area weed-free. After the flowers have faded, allow the foliage to die back naturally; this ensures the bulb stores enough energy for the following year's growth.
