Siberian irises

Siberian irises come from the specie iris Iris sibirica and produce some of the most delicate flowers of all the large and varied iris family. Although they will grow anywhere, they are ideal for gardeners who have a wet or acidic soil where bearded irises tend to rot off and fail to grow.

What Are Sibirica Or Siberian Irises

The Flowers Of Siberian Irises

They flower around the same time as bearded irises but the blooms are smaller. Some have delicate slim petals, more modern varieties have petals that are thicker and flare outwards. Often these produce more flowers than older hybrids and last longer. When it comes to flower colour, this is less diverse than Bearded Irises with shades of white, lilac and blue with lots of yellow varieties are becoming available. The blooms are carried on stiff, slender stems above the leaves creating a graceful plant.

The Leaves Of Siberian Irises

Sibirica, or siberian irises as they are often called, have slender leaves, which can form a very upright clump. Some varieties have thicker leaves that might arch out slightly, but generally, like all irises, the foliage is well behaved.

Where Do Siberian Irises Grow

These are very tough plants thriving in almost any condition from sand to thick clay soils. In lighter, less moist soils they may take a while to establish, and need frequent watering to start with.

What To Grow With Siberian Irises

Because most Siberian irises are robust they can be combined in borders with other perennial plants. The rhizomes, from which the roots grow, at the base of the plant.

How To Care Siberian Irises

Unlike Bearded irises, Siberian irises do not need to be regularly divided. The rhizomes are much smaller and therefore don't clamber over each other unlike the large rhizomes of Bearded irises, which over a three or four years will sap the soil of nutrients. Remove the leaves that die back in autumn at any time before the new leaf shoots emerge in spring.
