Iris chrysographes 'Kew Black'



Habitat: sunny, open position


Soil: moist with plenty of humus


Height: 60 cm


Flowering: summer


Width: 30 cm



These irises are usually used in damp places and bog gardens, but they grow well also in drier places. They make robust clumps of long, narrow leaves, and the stems of narrow-petalled flowers stand up well above the foliage. There are just a few species, but many selected varieties.

Iris chrysographes 'Kew Black' is particularly good form with very, very dark purple, almost black, flowers on upright stems. It will grow best in full sun but with plenty of humus in the soil to conserve moisture.

Iris Sibiricae series (Siberian irises) - some other suggestions
iris_bulleyana.jpg Iris bulleyana is the normal, purple-flowered form of this species, propagated from a recent introduction. The flowers are mid purple, with darker purple veins on the standards and on the falls, which have a light yellow zone.
iris_bulleyana_black_form.jpg Iris bulleyana black-flowered are seedlings from two plants with black (very dark purple) flowers. They have very dark flowers.
iris_bulleyana.jpg Iris cf. bulleyana has not yet been identified, but it is clearly a member of this group. Probably it will have purple flowers with patterns of orange and blue and white on the falls.
iris_chrysographes_black.jpg Iris chrysographes black-flowered represents plants vegetatively propagated from a plant with extremely dark flowers, effectively black.
iris_clarkei.jpg Iris clarkei is one of the easily grown Sibirica irises, coming from the Himalaya, specifically in this case from West Bengal, near the border with Nepal. The flowers are described as violet or blue or purple, in practice a colour that is a mixture of these, with a large white patch on the falls, the patch having a network of violet veins.
iris_delavayi.jpg Iris delavayi is the largest of the species in this group, and this is an outstanding form, robust, up to 2 metres tall, with large, deep purple flowers, quickly forming a good clump of strong shoots.
iris_forrestii.jpg Iris forrestii was acquired as an unidentified species, and at that time we had never seen wild Iris forrestii, so it was a very pleasnt surprise when this flowered. Yellow flowers with red-brown veins appear in succession from early summer.
invisible.gif Iris sanguinea 'Snow Queen' is an outstanding variety, originating in Japan, with clear white flowers.
IMH_7435.jpg Iris SDR7962 is the most prolifically flowering iris I have ever come across. It was just in one meadow, which must be fantastic at flowering time. The local people said it had purple flowers, and it appears to be in the bulleyana/chrysographes group, but was several hundred miles from the usual home of these species.
iris_sibirica_pale_purple.jpg Iris sibirica has violet blue flowers, darkly veined.
invisible.gif Iris typhifolia is a species from northern China and Mongolia, where it is found in wet areas near lakes. It has long, narrow, twisted leaves (the name means that it has leaves like a bullrush - or cat-tail to an American), and large, deep violet flowers.
IMG_7493.jpg Iris wilsonii is one of two yellow-flowered members of this group. Some people think it should be combined with what we know as Iris forrestii amd possibly also with I. bulleyana (but under the oldest name I. wilsonii). It has rather narrow petals, bright yellow, with dark markings on the falls.
