Contents

Description

Iris danfordiae has a narrowly ovoid, [3] bulb, [4] with whitish netted coats. [5]

It has 2 leaves (per bulb), [5] [6] 30–45 cm (12–18 in) tall. [7] They are linear, [8] four-angled in cross section, [6] [9] and gray-green, [8] or bluish green. [5] The leaves sometimes appear together with the flowers, [8] and sometimes after the flowers. [6]

It has a slender stem, that can grow up to between 7–15 cm (3–6 in) tall. [6] [7] [8] They hold 1 flower each. [5] [8]

It is one of the first reticulata irises to bloom, [10] [11] even blooming through the snow. [12] In early spring, [4] [7] between January, [7] and March. [9]

It has fragrant (scented of honey, [10] ) flowers, [13] in shades of yellow. [14] From bright yellow, [10] [15] [16] deep yellow, [8] to orange. [9] The flowers are 3–6 cm (1–2 in) in diameter. [8]

Like other irises, it has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals), known as the 'standards'. [17] : 17  The falls are spathulate (spoon shaped), [8] and spotted olive-green, [8] [9] or green. [6] [11] [16] In the centre of the falls is a deep yellow or orange crest. [14] [10] The standards are vert short, [8] [14] in some cases just bristles. [6] [16]

Later after flowering, it produces a seed capsule. [8]

Genetics

As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings. [17] : 18  It was counted in 1959 by Randolph & Mitra as 2n=27, then in 1997 by Johnson & Brandham as 2n=18 and 27. [3] [14]

Taxonomy

It is pronounced as (Iris) EYE-ris (aphylla) dan-FORD-ee-ay (danfordiae). [15] It is commonly known as dwarf iris, [18] buttercup Iris, [15] or Danford's iris. [15] [9] [19]

This species was introduced from Cilicia, [20] Turkey in 1876, by Mrs C. G. Danford (an English plant hunter of the Asia minor regions). [16] [21]

It was first published and described as Xiphion danfordiae Baker and described by John Gilbert Baker in J. Bot. Vol.14 n page 265 in 1876. [3] It was then reclassified and published as Iris danfordiae by Pierre Edmond Boissier in 'Fl. Orient.' Vol.5 on page 124 in July 1882. [1] [20]

Iris danfordiae is an accepted name by the RHS, [22] and it was verified by United States Department of Agriculture and the Agricultural Research Service on 23 January 1989, then updated on 2 December 2004. [2]

Distribution and habitat

It is native to temperate Asia, [2] mainly Asia Minor. [9]

Range

It grows in the Taurus Mountains of southern Turkey. [10] [6] [14]

Habitat

It grows on exposed dry rocky and sunny slopes, at the edges of coniferous forests or woods, [14] close to the snowline. [8] [6] It is normally found at an altitude of 1,000–2,000 m (3,300–6,600 ft) above sea level. [8] [6]

Cultivation

It is cold hardy, [14] to between USDA Zones 5 - 9. [18] [9] [15] It is sometimes deemed less reliably perennial than other bulbs. [11]

It prefers to grow in neutral to alkaline soils, which are high in potassium and phosphate. It prefers sandy and well drained soils both in summer and winter. [12] It prefers positions in full sun. [8] [15]

It is suitable for a rock or gravel garden or front of border. [23]

During mild season the bulb and plant is susceptible to slug damage. [6]

Propagation

It can be propagated by division or by seed growing. Seeds are best grown by collecting dry, mature seed capsules, and sowing the seeds. [15]

Division, is carried out by lifting the main bulb and splitting into many bulblets, [6] that (once replanted) can take many years to reach flowering size. [6] [24] This is best carried out when the foliage has died down. [25]

The bulbs should be planted deeply to flower reliably in later seasons. [10]

Hybrids and cultivars

Iris danfordiae has the following cultivars: 'Atilla', 'Bornmülleri', 'Danfordiae Hort'. [3]

Toxicity

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] [26]
