Iris 'Frozen Planet'

iris reticulata bulbs

Product Image
Ice-white flowers appear in late winter and early spring, each tipped with a flush of cool blue. Originating from alpine meadows, 'Frozen Planet' looks great when planted in drifts in a gravel garden or alpine bed. They're also easy to grow in pots, and will make a really gorgeous tabletop or windowsill arrangement.

How to care for Iris Frozen Planet:

Plant Iris reticulata bulbs in autumn, around 8-10cm (3-4in) deep and 8-10cm (3-4in) apart, in well-drained soil and a sunny position. They thrive in rock gardens, gravel areas, or pots where excess moisture can drain freely. Water after planting and allow the soil to dry slightly between waterings, as the bulbs dislike sitting wet.

After flowering, allow the leaves to die back naturally so the bulbs can store energy for next year. Once the foliage has withered, reduce watering and keep the soil on the dry side through summer dormancy. In pots, you can move the containers to a sheltered, dry spot over summer or lift and store the bulbs until autumn replanting.
