Description edit

Iris hyrcana has spherical bulbs,[1] that are coated with a solid brown fiberous network.[2]

The leaves appear after flowering,[2] it has 10 cm (3.9 in) high stems.[3][4]

In the Northern Hemisphere it blooms in the winter, between November and January,[5][3] or sometimes in February.[2] The flowers are around 2.5–3 cm (0.98–1.18 in) wide.[2][4] The flowers are much smaller than those of other Reticulata irises.[2]

Like other irises, it has two pairs of petals, three large sepals (outer petals), known as the "falls", and three inner, smaller petals (or tepals), known as the "standards".[6]: 17  They come in shades of blue, from clear blue,[5][3][7] to dark blue and purple.[2] The falls have a bright yellow ridge,[5] or orange mark.[2][7]

Biochemistry edit

As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings.[6]: 18  It was counted as 2n=20,[2]

Taxonomy edit

The specific epithet hyrcana, refers to Hyrcania, a historical region composed of the land south-east of the Caspian Sea in modern-day Iran.[8]

In 1848, specimens of the plant were originally collected in Azerbaijan.[9] It was described and published in 'Flora Kavkaza' by Alexander Grossheim in 1928.[10]

Iris hyrcana is now an accepted name by the RHS,[11] and it was verified by United States Department of Agriculture and the Agricultural Research Service on 4 April 2003, then updated on 11 December 2024.[12]

It is listed in 1995 in 'Vascular Plants of Russia and adjacent States (the former USSR)' by Czerepanov, S. K.[13]

It was once thought to be a variant of Iris reticulata,[2][5] except Iris hyrcana has spherical bulbs where as Iris reticulata bulbs are drop shaped.[1]

Distribution and habitat edit

Iris hyrcana is native to temperate areas of western Asia.[12][2]

Range edit

Originally found in the Hyrcanian woods,[3] along the southern coast of the Caspian Sea from Azerbaijan to Iran.[1][12][2]

Habitat edit

It is found growing in the mountains along the Caspian Sea.[2]

Cultivation edit

It prefers to grow in sunny sites, on rocky soils that dry out completely in summer.[2]

As it is not very hardy, but it can withstand strong frosts of short duration.[2] Although it is thought to be best grown in the UK and in America, within a bulb frame or alpine house,[5] to keep the soils dry.[2] It also needs a dry, summer dormancy of several months.[2]

A specimen of Iris hyrcana won the Farrer Medal at the AGS Caerleon Show, in South Wales, shown by Bob and Rannveig Wallis.[14]

Toxicity edit

Like many other irises, most parts of the plant are poisonous (rhizome and leaves), if mistakenly ingested can cause stomach pains and vomiting. Also handling the plant may cause a skin irritation or an allergic reaction.[15]
