Siberian Iris-Iris Sibirica 


The Siberian Iris also known as the Siberian Flag is a rhizomatous herbaceous perennial native to Central Asia and Europe. The classification rhizomatous means the plant has a mass of roots commonly referred to as rootstocks which are the modified subterranean stem of a plant which retains the ability to produce new shoots. Herbaceous perennial is a classification of a plant which returns the next year and has no persistent woody stem above ground. Meaning at the end of the season it will die and spring up from the root in the upcoming season.

The Siberian Iris is branch stemmed with green grass-like leaves that are ribbed and occasionally have a pink tinge at the base of some leaves. They usually are shorter than the flowering stems which at maturity measure between 50-100cm (20-47in) high. Each flowering stem of which there are often 1-3 per plant bears anywhere between 2-5 flowers during late spring to early summer. The flowers which themselves are 6-7cm (2-3in) in diameter are different shades of blue including blue-violet and occasionally white. Each flower has two pairs of petals consisting of 3 large outer petals (sepals) and three smaller inner petals (tepals). The sepals which measure 5-7cm (2-2.8in) long and have beautiful dark blue veining droop down exposing the tepals which have lighter veining, smoother texture and measure 4.5-5cm (1.3-2.0in) long.

The iris can tolerate temperatures as low as -20 degrees Celsius (-4F) and is hardy to USDA (United States Department of Agriculture) zone 2-8 as well as zone H1. It should be noted that if mulched the plant can withstand colder temperatures. This plant thrives in fertile and slightly acidic soil with a PH level higher than 5.6. If utilizing clay or sandy soil types, an organic fertilizer (manure or compost) should be applied at the time of planting. While this plant enjoys full sunlight, it can tolerate partial shade, especially in very hot and arid climates. Watering is needed during the growing season (spring and summer) for best blooms and can tolerate occasional flooding but should not be left in standing water.

These plants can be placed waterside and are ideal big garden plants. They also make beautiful additions to naturalized gardens by planting them alongside other perennials and grasses. The Siberian Iris also makes a pretty herbaceous border, and they are an excellent addition to gardens in general.
