Product Information

Full details

The Thompson and Morgan Iris Dutch Mixed Spring Planting Bulbs are an ideal choice for gardeners looking to add vertical interest and vibrant color to their landscape during the transition from late spring to early summer. These elegant, orchid-like blooms in shades of blue, purple, yellow, and white are perfect for those who enjoy fresh cut flowers, as their sturdy, straight stems make them excellent for indoor floral arrangements. While they provide a stunning architectural display, success relies on planting them in well-drained soil, as they are susceptible to rotting in overly damp conditions.

FAQs

When is the best time to plant these bulbs?

These bulbs are intended for autumn planting to ensure they establish root systems before the spring growth cycle.

Can I grow these in containers?

Yes, they thrive in pots provided you use a well-draining soil mix and ensure the container has adequate drainage holes.

How deep should I plant the bulbs?

Plant the bulbs at a depth of approximately 10 to 15cm with the pointed end facing up.

Do I need to lift the bulbs every year?

No, they can be left in the ground if the soil drainage is excellent, but lifting is recommended in areas with very wet winters.

Are these bulbs deer or rabbit resistant?

While generally less preferred by herbivores than tulips, no bulb is entirely immune; consider deterrents if you have high pest activity.

How long do the cut flowers last?

If cut at the proper stage and placed in fresh water, they can last up to a week in a vase.

Troubleshooting

Bulbs failing to sprout

Check if the soil was too wet during winter, which can cause the bulb to rot before growth begins.

Weak or floppy stems

Ensure the planting location receives adequate full sun; insufficient light often leads to leggy, weak growth.

Flowers not blooming

Verify that the bulbs were not planted too shallow or too deep; the standard planting depth is roughly 10-15cm.

Pros and Cons

Pros

  • High-quality, long stems suitable for cut flower arrangements
  • Stunning architectural appearance in garden beds
  • Generous 160-pack quantity for expansive landscape projects
  • Thrives in full sun conditions
  • Easy to establish in standard garden soil

Cons

  • Requires very well-drained soil to prevent bulb rot
  • Flowering window is limited to late spring/early summer
  • Not suitable for heavy, waterlogged clay soils without amendment

Setup, Compatibility & Care

To ensure healthy growth, plant the bulbs in autumn in well-drained soil, ideally in a location that receives full sun. Dig a hole approximately 10 to 15cm deep, placing the bulb with the pointed end facing upward. Space each bulb about 10cm apart to allow for proper airflow and root development. During the active growing season, keep the soil moderately moist but never waterlogged. After the foliage begins to yellow and die back naturally after flowering, allow it to remain for a few weeks; this process helps the bulb store energy for the following year before you tidy the area.
