Description

Iris serotina grows to a maximum height of 60 cm (24 in) tall and the narrow leaves are 2–6 mm wide and grow between 30–60 cm (12–24 in) tall.[2] They appear in the autumn,[3][4] but then fade before flowering.[5]

It normally has 2 - 3 flowers per stem,[5] and generally blooms in late July, or August.[6]:287

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'.[6]:17 It has blue-violet flowers,[4] the petals are veined with a deeper violet colour, and the falls are marked with a yellow patch.[4][6]:287

Its seeds are small, yellow and semi-circular.[2]

Taxonomy

The specific epithet serotina, refers to the Latin word, 'serotina' meaning late in flowering.[7][8]

In 1861, Heinrich Moritz Willkomm described Iris serotina after seeing plants from Province of Jaén (Spain).[9] Originally, he called it Iris filifolia, but this was later corrected to Iris serotina.[10] Then published in 'Prodromus Florae Hispanicae' Vol.1 in 1861.[11][12] It was later illustrated in Curtis's Botanical Magazine No.733 in 1977.[5]

Iris serotina is an accepted name by the RHS,[13] and it was verified by United States Department of Agriculture and the Agricultural Research Service on 4 April 2003, then updated on 3 December 2004.[14]

Distribution and habitat

Iris serotina is native to temperate areas of Europe.[13][14]

Range

Originally found in South eastern Spain.[6][14] It has been found in Cuenca, Jaen and in the Province of Granada. It also has been found in Rif in Morocco.[9][14][15]

Habitat

It grows on rocks, on the shadow side of the mountains.[4]

Conservation

It is classed as 'Endangered',[4] and was on the 1997 IUCN Red List of Threatened Plants in Spain.[16]

Cultivation

It is best grown in a bulb frame or a very sheltered dry border, in the UK.[17]

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.[18]
