Plant Profile: Dwarf Iris (Iris reticulata)


Dwarf IrisThe official start of spring is less than 8 weeks away but most gardeners consider March 1 to be their beginning of spring. And it’s around this time of the year that you’ll find Iris reticulata, or Dwarf Iris, blooming in your garden if you’re fortunate enough to have a planting.

Dwarf Iris are delightful little early spring bloomers with purple to blue flowers with a yellow highlight on the falls. They are often seen poking through a light layer of late winter snow with no bother. At 6″-8″ tall, they can fit in nearly every garden and are often used in rock gardens. I think they look great along pathways or by doorways where they can be viewed up close. If allowed to naturalize into a colony, they can make quite a show even from afar.

Dwarf Iris require no special cultural conditions other than well-drained soil. They prefer full sun and that is easily achieved under deciduous trees even in an otherwise shady landscape. They will tolerate light to moderate shade but shouldn’t be planted underneath dense evergreens such as spruce or hemlock. Their foliage, as with other spring blooming bulbs, should be left intact until it turns brown on its own. With such a small stature, the drying foliage shouldn’t cause much of a distraction in the garden.

Dwarf Iris originate from a bulb instead of a rhizome like the popular German Iris. This makes it easy to propagate them to plant in other areas of the garden or to share with a friend. The bulbs should be planted in autumn so if you didn’t plant them last fall, you’ll have to wait a few more months before you can add them to your gardening palette.

Other noteworthy characteristics of these spring bloomers is that their blooms are fragrant and the plants are deer resistant. Remember, deer resistant doesn’t equal deer proof! Plant them in an area where their sweet fragrance can be enjoyed and you’ll be rewarded for years to come.
