When to Plant

Depending on the species, your bulbs will flower from February to March or May to June.
For example, if you have our Iris Reticulata Pixie or Alida, the bulbs should be planted mid-autumn to see them flower in early Springtime.

However, if you have our Iris Dutch Blue Pearl or Bronze Perfection, then you should plant them late autumn so that they flower in the summer.

Where to Plant Iris Bulbs

Like all iris plants, bulb variations still require a lot of sunlight to grow efficiently. With that in mind, ensure you plant your iris bulbs in well-drained soil that is in an optimum position to catch a lot of rays.

You can plant your irises in borders, containers, or pots. They can even be developed in a greenhouse to then become a houseplant. Irises can also be cut for bouquets, which will not affect the growth of your plant later.

How to Plant your Bulbs
