Iris Evansia, Iris Japonica, Crested Iris, FAIRYLAND



Dainty white speckled florets smother this plant making a truly welcome display that starts in late winter and continues until the Tall Bearded Iris. Flowers are listed as in the checklist as B7 (Pink to Red toned self) which is just so completely wide of the mark. This plant has smaller growing sword like glossy green leaves, has no canes but sheathed stolons spread from plants traveling close to the surface quickly establish new plants that lead to form a large clump. In New Zealand  'Fairyland' grows best in semi shade as our harsh sun tends to badly burn the leaves. Registered by James C. Stevens of New York and introduced by Samuel Berry of Redlands, Southern California, who specialised in species Iris. My 'Fairyland' plant was gifted to me by Mary Richardson of Upper Hutt, whose garden is just full of New Zealand Iris History and also pleasantly packed with Iridaceae bulbs that put on a bold complementary display in the spring and early summer.

Iris Evansia, Iris Japonica, Crested Iris, BOURNE GRACEFUL



Medium size flower which is deep lilac-blue with strong orange-yellow signal surrounded by old gold to dark violet flecks and a violet border around the white signal area. The flowers are borne on distinctive green stems that become darker towards the bottom, but the plant itself has no canes. The long glossy leaves are ribbed and coloured purple at the base (PBF)

The Iris Yearbook (BIS), 1975,"An Iris Japonica Seedling", J.R.Ellis.
From pollination's of the Ledgers variety of Iris japonica with pollen from the plant recorded as the Capri form of Iris japonica ( B I S Yearbook 1966 page 138) a vigorous hybrid has been obtained which has been registered as 'Borne Graceful'. For the last two years this hybrid has been grown in a cool greenhouse where it has flowered profusely from the end of March to the beginning of June. The flowering spikes reaches a height of 4 feet and the flowers which are 2
½ inches to 3 inches across are pale mauve in colour with a deep yellow crests surrounded by deep mauve spots.
Cytologically, the hybrid has approximately 61 chromosomes and this is the highest chromosome number recorded in Evansia irises. The parental species, Ledgers variety and the 'Capri form' have a 54 and 31 chromosomes respectively and the higher chromosome number in the hybrids stems from the fact that neither parent forms are cytologically true species. Ledgers variety with 54 chromosomes has been reported by Chimphamba (Cytologia 38:501-514, 1973) to have a triploid chromosomal constitution and in crosses with I.cofusa give gametes with different chromosome which range from 24 to 30 chromosomes (unpublished data). The 'Capri form' of I.japonica was also by Chimphamba to have a chromosome complement indicative of hybrid origin. It is highly sterile because of meiotic difficulties, but produces a few functional pollen grains which, in all probability have not been reduced in chromosome number. An unreduced gamete with 31 chromosomes from the 'Capri form' together with a 30-chromosome gamete from Ledgers variety have almost certainly combined to give the hybrid 'Bourne Graceful'.

Iris Evansia, Crested Iris, CHENGDU.




The Evansia or Crested Irises are a interesting group of different irises all with different chromosome counts. 'We at home' are just starting a collection of these plants now that the trees we planted some 18 years ago are starting to give the mottled shade habitat that evansias like so much to grow in. Evansias do like growing in many places in New Zealand and these delightful and distinctive irises add great value to the garden, although they are not used as much in gardens as they deserve to be. 
 Much has been said and written about the 'DNA' of 'Chengdu', some have suggest it is a natural form of I.confusa and other more enlightened folk have suggested it is a species of its own. What we do know for sure that it was collected in Sichuan, South West China by Jean Gardiner and sent to Jean Witt in America. It forms a dense clump of glossy rich green leaves that are held in fans, bottom of this foliage strongly tinted purple-black, Historic Iris aficionados refer to this as PBF. The branching bloom stalks rise to a height of 102cm (42"). Blooms for several months in Spring with exquisite almost orchid-like 4-4.5cm blooms in contrasting shades of deep lavender that have a bright yellow crest surrounded with white which in turn is surrounded with a prominent purple zone which extends as veins towards the blade of the fall. Slight vanilla fragrance.
 
The Iris Yearbook (BIS), 1991,  “Evansia Irises : Two New Species”,  page 96, Dr. Jack R. Ellis.
The second potential new species I. "wittii", is named (without permission) after Mrs Jean Witt of Seattle who kindly sent a plant approximately ten years ago, with details of its origin/location in south west China. It was received as a probable form of I. confusa. With smaller growth form, more delicate inflorescence and with mid violet-purple flowers, it is morphologically quite distinct from all previously introduced forms of I.confusa. It has recently been cytologically studied by Young Lim, who has noted chromosomal differences from I."confusa', I. "wattii" and I. "nova". The cytogenetic evidence combined with the morphological differences would justify its recognition as a different species in the cane bearing Evansias assigned to group 1.

Gardening with Iris Species, Proceedings of an International Symposium, Edited by James W. Waddick, 1995.
'Following the Evansia Trail, From a Question Mark', Revie Harvey, New Zealand.
The latest edition to our Evansia collections has not to our knowledge been given an official title. It is very popular with all growers and viewers and is commonly called "Chengdu" in honour of the district in China from whence it was discovered in recent days. In this Southern Hemisphere, it has adapted well to seasonal climatic conditions. The bright green foliage is attractive in the off-season. The florets are small but neatly proportioned in mid-violet-blue and by far the most colourful of the range. For a period there was a theory that it was another form of I. confusa, a view that I refuse to accept and I felt was proven when I grew the two plants in close proximity. Like all Evansia forms brought into cultivation from the wild, it is a reluctant pod parent. However seedlings raised from a bee pod have been true to the blue parent. At this time the first blooms are being from a cross of "Kilkivan" with 'Chengdu" showing some variance from both of the parents.

Evansia or Crested Irises
Two evansias more recently available are I.'Nova' and I. 'Chengdu'. The first of these two is a tall plant that sets seed reliably and has large white blooms marked with gold. It was found in a garden in the U.K., but has not yet been found in the wild. I. 'Chengdu', however, came from China, and it appears from a recent study that it might be a species in its own right. It has glossy dark green leaves and deep lavender flowers with a prominent purple zone surrounding the white area adjacent to the the deep yellow crest. Its growth habit is similar to I. confusa and is very similar to a variety named 'Martyn Rix'.

Iris Bucharica a really wild show




Introduced in England in 1902, having all the airs and graces of antiquities with it's very Persian look is delighting us with it's start of bloom today. Very easy to grow just plant and forget but please remember where you planted it as you could pull it out as a strange weed!
 As a reference for your information I have copied below the expansive writings of Sir Michael Foster regarding these bulbs collected by others in Bokhara (the capital of the Bukhara Province,Uzbekistan) published in The Gardeners’ Chronicle 1902, the article is also noted as a source of information regarding the identification of Iris Bucharica in the American Iris Society Checklist of 1929.

The Gardeners’ Chronicle, June 14th, 1902.

NEW OR NOTEWORTHY PLANTS. 
NEW  I R I S E S. 
In the course of last year Messrs. Van  Tubergen received from their collector in Bokhara a consignment of bulbs obviously belonging to the Juno group of Irises, collected in that country. They arrived in several numbered collections, presumably gathered from different spots; but on flowering proved to belong to two forms only, to which, for reasons given below, I have ventured to apply the above names.

Iris Bucharica, Foster, sp. n.
Bulb similar to that of I. orchioides, but in the specimens received more globose. Stem, about 1 foot or 1½ foot high, bearing six or seven leaves, each of which sheathes the stem at its base, and three, four, or more flowers. So far the plant in its general features resembles I. orchioides, but the leaves are somewhat shorter and less gradually pointed, and more distinctly striated on the under surface. Moreover, while in I. orchioides each flower is set on a distinct peduncle, in this plant the peduncle is quite short, or the flower is actually sessile. The horny margin of the leaf bears, as in I. orchioides, a number of inconspicuous setæ. The plants are smaller, shorter, and more slender than those of I. orchioides, but this difference may disappear on further cultivation. Spathe valves, as in I. orchioides, longer than the tube, narrow, not inflated, slightly scarious at the tip.
The outer petal, fall, consists of a strap- shaped claw, -which, after an inconspicuous constriction, expands into a much broader, obovate, emarginate blade, which bears on its hinder two-thirds a large plicate crest, continued along the claw as an inconspicuous median ridge.
The claw is pare white in colour, the blade with the crest a rich golden yellow, which suddenly ceases where the blade joins the claw. By the side of the crest over the blade are a few diverging dark purple, almost black veins, varying in intensity in different flowers. Messrs. Van Tubergen inform me that some of the plants show variations in the markings.
The inner petal, standard, small, pure white, extended horizontally, consists of a caniculate claw expanding into a broader, flat, distinctly mucronate blade.
Styles large, pure white, with large white, quadrate, or in some plants deltoid crests. Anthers as long as, or slightly longer than the filament.
Tube about three times as long as the rounded, trigonal, thin-walled ovary.
Seeds not as yet seen. Ripening capsule, like that of I. orchioides, long, rounded trigonial
 Habitat, Eastern Bokhara, on mountain slopes, altitude 5000 to 6000 feet, on sides of river Sureh-ab, a tributary of the Amu Darya.
The points of specific difference between this plant and I. orchioides lie in the flower. In I. orchioides the outer petal is simply strap-shaped, with no obvious distinction between claw and blade ; and the crest is less conspicuous. In I. orchioides the inner petal is lanceolate, and never, so far as I have seen, distinctly mucronate, as in the plant now described. In I. orchioides the crests of the style are smaller, and the anthers are apparently always shorter than the filaments.

HOME CORRESPONDENCE
IRIS BUCHARICA
I find that my description of Iris bucharica (Gardeners’ Chronicle June 14th 1902, p 385), I underated it's, at least possible, dimensions. I have now in flower a plant whose stem is 22 inches high ; the lower leaves are 1 foot long, and 2½ inches wide at the broadest part. It bears no less than 10 flowers and in the flower the outer petal (fall) is 2⅞ inches long, by 1½ inches at its broadest, whilst the style is 2¼ inches long by 1⅛ inches at its broadest. It is really a very fine plant. M. Foster, Shelford.

Iris biliottii, Collected 1887, Sir Michael Foster, Part 2




     So as not to detract from the writings of Sir Michael Foster I have kept seperate the following additional information.

A HANDBOOK OF GARDEN IRISES By W. R. DYKES, M.A., L.-ès-L.
SECRETARY OF THE ROYAL HORTICULTURAL SOCIETY. AUTHOR OF "THE GENUS IRIS," Chapter 16, CERTAIN TALL BEARDED IRISES.
Under this heading it seems advisable to group and to attempt to describe and distinguish a number of Irises, which may or may not have an equally good claim to specific rank as those already described. It has already been explained that they are nowhere known to be certainly wild but, as the names are in frequent use among gardeners, it seems best to give particulars which it is hoped will enable each one to be recognised.
I. Biliotti. Foster, 1887. Named after Alfred Biliotti, a British Consul at Trebizond on the Black Sea, from whom Foster received plants in 1884. This is practically a germanica with long, narrow green spathes, not scarious. The falls are red-purple with brownish veins on white on the haft and the standards are of a bluer shade. The style crests are of an opal colour. The leaves are of a peculiar shape, being narrow at the base and having their widest point above the middle.

THE IRIS Brian Mathew.
The Species of Iris.

I. Biliottii
Foster. This grows in the Black Sea region of Turkey, especially in the valley leading from Trabzon to Gümüşhane where it is much use on graves. It has stems about 60-80cm in height with two or three branches 5-10cm long. The acute bracts are grey-green with transparent papery tips. Like I.germanica the flowers are scented and purple, the falls are rather reddish purple and the standards of a bluer-purple shade. The haft of the falls is veined brown-purple on white ground and the beard is white with yellow tips to the hairs.
I was shown this plant growing near Gümüşhane by T Baytop and can confirm that it is apparently confined to cemeteries and does not produce seeds. Rhizomes collected by us were brought back to England where they grow vigourously and flower freely a few weeks after I.germanica.

Iris albicans






Growing at home and a welcome addition blooming this morning, I.albicans is an early flowering, slightly fragrant heirloom iris of historical significance and could be classified as an Intermediate Iris. I. albicans is a natural hybrid that has found favour with gardeners for at least the last 800 years. Marc Simonet in his published thesis ‘The Genus Iris, Cytological and Genetic Research’ states that I.albicans among other listed species possesses (2n= 44) number of somatic chromosomes indicating that this species arose through a cross with a 40 chromosome species and a 48 chromosome species making it a hybrid.

There is a lot of conjecture about what ‘albicans’ parents are likely to be and to the precise origin of its homeland. No real proof has been forthcoming supporting any of these theories, and should there still be an interest in Irises in another 200 years not much will have changed regarding the current status of I.albicans.

I.albicans along with, Florentina, I. pallida, and I. germanica were all used in the production of Orris Root. The following could give much for the reader to consider;

CORNELL MEMOIR 100 Study of Pogoniris Varieties Austin W.W. Sand July 1926
I. albicans (species, Lange 1860)
Distribution; Perhaps native of Yemen in Arabia and widely distributed by, the Mohammedan’s, Spain, France, Crete, Cyprus, Asia Minor. Colour effect a self, standards and falls, white. Standards pure white; shape, rounded oblong, narrowing suddenly; haft short, canaliculate, without hairs, faintly veined with yellow. Falls, white; haft white; faintly reticulated with greenish yellow veins which do not extend to blade; blade obovate, haft wedge- shaped. Minor parts; beards, front white hairs with yellow, base deep yellow; style-branches ovoid, white, keeled; Crest narrow, pointed, serrate; pollen cream-coloured; spathe-valves navicular, broad green, hardly scarious at all or only in upper third when the first flowers open, 1½ inches long. Growth; rootstock a stout rhizome; habit compact; foliage leaves ensiform, somewhat wider than those of, I. germanica but the 15-18 inch long, branched, inflorescence resembling that of I. germanica but the lateral flowers more closely set on shorter branches which are almost entirely concealed in broad green bracts, terminal head sometimes 3-flowered; tube equal to or slightly longer than ovary; pedicle very short; ovary ¾ inch long, trigonal, with slight group on each face; stigma entire; filaments white, about equal links to the cream-coloured anthers.
Outstanding qualities; Compact branches of inflorescence, foliage stiff and broader and more twisted than in I. germanica no hairs on haft of standards falls appear pointed due to curling. Synonyms; I. florentina 1789, I. alba 1798 (might be I. germanica var. florentina),
I. albicans var. Madonna, 1892, differs from the type only in its blue color and its purple flushed spathes

'The Unconventional Garden', Sir Arthur Hort, published 1928. Pages 206-207
To complete the account of wild T.B.’s, mention should be made of the lovely pure white Iris called albicans, which is fairly common in our gardens and which does not come under any of the three clans just described. This plant seems to set no seed and to produce no effect upon, wherefore (unhappily) it has no place in the record of the origin of the garden hybrids. (In 1927 I for the first time obtained a few apparently sound seeds; what may come of them remains to be seen) But it has an interesting story to tell. It was conjectured by Dykes to be an albino form of an Arabian species called Iris Madonna, whose flower is of a bluish purple shade. Now this typical form is not common anywhere, but albicans is found all along the Mediterranean coast where ever the Moslem invaders from Arabia penetrated, having been planted by the Mohammedan in their cemeteries. It looks as though they had bought it with them as they wandered westward. I have grown forms of it, from Egypt, Greece, Sicily, Spain, Madeira ; the finest perhaps is one which I begged from the hotel garden in Syracuse which overlooks the “quarry” where the ill-fated Athenians were starved to death in B.C. 413. I have recently had some confirmation of Dykes' surmise having noticed a flower of albicans with the purplish streak on the pure white, a reminiscence of the purple-flowered Madonna from which it sported centuries ago.

'Rainbow Fragments', Chapter 2, Historical and Otherwise, J Marion Shull, 1931.
The lack of certainty as to place or time of origin or native habitat in case of indigenous species, leaving all to veriest conjecture, is due no doubt to various causes. All history of every kind is lost in a sufficient degree of antiquity, and doubtless some of these plants were cultivated longer ago than there were records to bear out. Then the very nature of the rhizomes, so constituted that they can withstand months of ill treatment and still retain the spark of life, capable of quick recovery when conditions again are right, has made both purposed and accidental distribution relatively easy. Thus Iris albicans, whose origin is likewise lost beyond recovery, is known to have made a special appeal to the Mohammedan’s faithful who, whether they invested it with sacred character or merely adopted it as a conventional ornamentation, made habitual use of it upon the graves of their dead, and so it spread where ever the roving character of the fiery followers of the Prophet lead them to live and die. Thus it doubtless spread westward from Asia Minor across northern Africa and into Spain, whence it must have been carried to the New World, since it is found, apparently escaped from cultivation, in the region of the Sierra Madre in Mexico.

 Hardy Bulbs, Volume I, 'Iridaceae', Lt.Col.Charles Hervey Grey, Published Williams & Norgate, London, 1937.
albicans, Lange. VII. Often listed as I.
florentina. It is of obscure origin, as it is widely distributed as a cultivated and a naturalised plant throughout southern Europe. In all probability it was introduced from Arabia the Mahomedans, who always use it as a cemetery plant. The rhizome is solid, compact; the leaves thick, rigid, those in the centre of the clump having a spiral twist; the blade of the falls obovate, pure white, the haft cuneiform, with a few pale green lines, the beard mainly deep yellow, with a few white hairs, yellow tipped in front; the standards oblong, pure white, of good substance, with a narrow, canaliculate haft; the styles White, ovate; the crests narrow, acute. The flowers are produced in May. It requires a warm situation and a fairly stiff, well-drained soil.
 var. Madonna, hort. Sprengel. A form with blue purple flowers. Its needs are identical with those of the type.


'IRIS' Fritz Köhlein pg.196
Iris albicans Lange
In 1860, Lange gave this name to the white Iris which he found in the vicinity of Almeria, Spain. The actual homeland of this Iris is probably the Arabian Peninsula; it was disseminated during the wave of Islam expansion over Africa and South West Europe, carried along to be planted on graves of former Muslim warriors. Grows all over the Near East, in Libya, Tunisia, Algeria, and Morocco. The Spaniards carried it to Mexico. Thus I. albicans is also found growing wild all over these countries as a volunteer from gardens. It grows on sunny embankments and slopes. Planted on graves in many Moslem regions.
I. albicans can easily be distinguished from I. florentina the other old, white Iris by its branching habit. While I. florentina has good branching, the blossoms of I. albicans are held quite close to the stem. I. albicans also has no hair at all at the base of the standards, and its spathes are more or less papery at the top when the plant blossoms. I. albicans has somewhat wider leaves that tend to twist, a bit giving the plant and unusual appearance. The bottom colour is pure white in the beard is yellow.
Lange called this widespread white form I. albicans; a less common form was blue-violet blossoms, found in Yemen, has been called I. albicans ‘Madonna’ or I. albicans var. madonna. Except for the blossom colour, both variants are practically identical.
This Iris is for collectors or a welcome souvenir from a vacation. It is very robust and warm regions with good drainage, but acts like a “spoiled brat” in cold areas. More prone to rhizome rot than I. florentina. New leaves develop fairly late in the fall, so that either the tips or the whole leaf suffers in the cold winters. Blooms freely in the right location. Division is preferable; rarely propagated by seed. Number of chromosomes 2n= 44 (M. Simonet 1932).

'The Iris', Brian Mathew, 2nd. Edition. 1989
Iris albicans Lange. There has frequently been some confusion between the species, which occurs wild in Arabia, and Florentina, the albino version of I. germanica. In 1802 it was beautifully figured by Redouté under the name of I. florentina and it was not until 1860 that it was given specific status, when Lange named it I. albicans.
It is a stocky plant usually 30 to 60 cm in height in the wild, with short broad (1.5-2.5cm wide), very green-grey over wintering leaves which are abruptly narrowed to an incurving tip. The scheme has one to three terminal flowers and is often unbranched but may have one in either sessile lateral flower head. The sweetly scented flowers are about 8 to 9 cm in either pure white or blue, produced from very broad blunt bracts which are green or purplish tinted in the lower half or two thirds, and papery-transparent in the upper part. The beard is a white hairs, tipped with yellow, and there is a greenish-yellow flush to the hafts of both the falls and the standards. It is the blue-flowered form has been given the name ‘Madonna’.
‘Florentina’ is easily distinguished from I. albicans because the bracts are almost wholly brown and papery at flowering time, the lateral flowers are stemmed and the flowers are very slightly flushed with pale blue, not is pure white as in the white form of I. albicans. Additionally, ‘Florentina’ has narrower leaves which are green in colour.
I. albicans is a native of Saudi Arabia and the Yemen Arab Republic where it grows in dry rocky places or on banks at altitudes up to 2700 metres. New material has been collected in recent years and introduced into cultivation and it seems to be a ‘good’ wild species. Both the blue and white forms occur in natural populations, although the latter seems to be much the most common. It seems fairly certain that I. albicans has been distributed through western Asia by man as a plant to adorn graveyards.

'The Book of Iris' by R. Lynch published in 1907 listed 'Florentina' as I.florentina a species, and surprisingly lists albicans as Var.albicans a hybrid of florentina.
Var. albicans (Lange) Ic.Plant. Hisp., t. 33. Flowers pure white; perianth tube ¾ in. long; limb 3 in; beard pale yellow. The spathe-valves are shorter than those of the type, and the inflorescence is more compact. Flowers later than I.florentina. There is a garden form named “Princess of Wales.” Native from Spain to Cyprus.

Siberian Iris "GOLYBAYA LAGUNA"




When I asked if I could use this photo, Sergey's reply was certainly but he could not understand why as he did not like it much but qualified the statement by adding "but its all a matter of taste". I myself think it most certainly is a mighty good looking Siberian and the dark blue veining on the standards and the falls give the bloom another dimension in taste.

The pod parent is "China Bitone" which has the species Iris I.typhifolia on both sides of it's parentage and is registered as a species X. The pollen parent is unknown.

As always, clicking the image will take you to the larger, higher resolution version.

Iris variegata 'var.Reginae'




Iris variegata 'var.Reginae', collected in Hungary in 1947 but I am most sure that this natural clone has been around many century's before the date it was collected. There must be huge amounts of these types of Irises in parts of Europe and Russia that western gardeners are still oblivious to.
Plant is about 40cm tall and the flowers size is approx. 6cm in height. Flowers just above the foliage and usually bears two or three lateral heads. Glaucous green ribbed foliage. It's one tough little plant.
Super species type for Heritage gardens.
I have no idea where this plant can be purchased from in New Zealand.
