Tall Bearded Iris CASCADE

A cross of two irises attributed to Fernand Denis the pod parent was the violet rose with a white ground claw heavily striated brown purple named 'J. B. DUMAS'  and this was crossed with the very rich coloured neglecta named 'AURELLE' with its light purplish blue standards, rich luminous purple falls with a a heavy gold beard. The result of this cross was the lavender purple self  named 'Cascade'.
'Cascade' was the first iris to be catalogued by Jean and the Iris was introduced in the 1930 A.H.Burgess Irises Catalogue "as a seedling of our own raising". It continued to be listed in the Stevens Bros. catalogues until 1942. It is a terrific iris of classic style and form, grows well with high plant health. Super large flowers that last well in both garden and the vase. Have no idea and can find no clues to why this iris never made the pages of a Checklist, but because it is not registered does not mean it does not exist.

Cascade This is a seedling of our own raising that was much admired by visitors to our gardens last season. It is a huge flower, measuring over six inches from the tip of the standards to the bottom of the falls. Colour is an even tone of light lavender purple : a true self ; 3½ ft................12/6

The reason why I have been hesitant  in posting this iris is the deluge of nincompoops that will find an iris that looks something like this iris and then list it on that collective madness known as Trade Me. So if you see an iris listed on Trade Me as 'Cascade' you can bet it most likely is not.

THE LAEVIGATA SECTION - Iris Laevigata

 Some Lesser Known Irises

  PART IV

THE LAEVIGATA SECTION

By Miss J. Burgess, Waikanae.

THE NEW ZEALAND SMALLHOLDER, May 16th, 1935.

The laevigata section of irises embraces the well known Japanese or Kaempferi hybrids. These hybrids have all been obtained from the single species Kaempferi, one of the four true species which comprise the group. Although essentially water lovers, the laevigatas, in common with all other irises, and with the sole exception of pseudacorus, dislike a badly drained soil.
Much confusion has existed between laevigata and Kaempferi, since they were first known to the European botanists a century ago. This is due to the fact that both species come from the same districts. They are found in swampy places near Lake Baikal, and along the banks of the River Amur. Thence, they occur eastwards through Manchuria, Northern China, to Korea and Japan. I wish to make it clear that where I write of Kaempferi, the reference is to the species Kaempferi, the source from which the Japanese have obtained their marvellous, but, I fear, rather monstrous, hybrids. By what means they have succeeded in modifying the wild type, and obtaining those huge double freak flowers, is a mystery. From the fact that they have obtained a double form of laevigata as well, we are forced to conclude that it was not merely a natural chance freak which gave them their first break, but a carefully guarded horticultural secret. And no part of the world, and in no section of the genus, has nature evolved for herself this form of freak flower. The double laevigata and the double Kaempferi of the Japanese are the only double irises in existence. In passing, it is interesting to note that the Japanese have done the same by the chrysanthemum and the cherry. But nature receipts the interference of these Oriental hybridists, and if their double hybrids are allowed to naturalise and seed, in a few generations the seedlings will throw back to the type of the wild species. Though first discovered to the Occident in 1837, the true laevigata is still uncommon in English gardens, and it is almost unknown here. This is no doubt due to the fact that until fairly recently it was taken to be synonymous with Kaempferi. Laevigata is chiefly distinguished from Kaempferi by the characteristic, which earned for it the name laevigata, which means "smoothed". The tall, sword shaped leaves are quite smooth, differing therein from Kaempferi, which carries down each leaf a distinct ribbing, or ridged veining. The colour of laevigata is a deep, rich blue, of a shade not seen in any other Iris. The standards are upright, and the falls tongue like, long and drooping. 

There is a garden form of the type under the name L. albopurpurea, having, as the name suggests, white and blue flowers. The standards and style arms are white, and the falls are white heavily mottled with blue. Strangely enough, this quasi-albino characteristic acts as a Mendellian recessive, and albopurpurea breeds quite true to colour. In recent years there has been on the market and Iris, which is called laevigata 'Rose Queen'. This is apparently a hybrid between laevigata and Kaempferi , as although the shape of the flower is like laevigata, the leaves posses the ridged veining of Kaempferi. The colour of Rose Queen is an even tone of Peach Blossom or rose pink. It is easily grown, and very effective when massed.
The cultivation of laevigata is quite simple. Like all the group, it dislikes lime, but can be grown successfully in any good garden soil, provided that it is not allowed to dry out during the summer months.

Kaempferi, as mentioned, comes from the same districts of Northern and Eastern Asia as does laevigata. It was first noted by a Western botanists as a species in 1858, but has been in cultivation in Japanese gardens for centuries. The shape of the flowers is somewhat similar to laevigata, but the standards are not so tall, and the falls are perhaps a little broader. The colour is a rich, deep purple, relieved on the half of the fall by a narrow stripe of Golden yellow. There is also a white form. Cultivation is the same as for laevigata, but the Japanese hybrids require more attention. These latter should be given plenty of manure, preferably well rotted garden compost or animal manure, which is best applied during winter when growth is inactive.

Pseudacorus, the English 'Water Flag' is botanically classed in the laevigata section. This act is surprising to the casual observer, but careful examination of the plants will discover many liberties with the species laevigata and Kaempferi. Pseudacorus, is too well known to come within the scope of  this series of articles, but, I might mention in passing, that it is well worth the attention of any Gardener with plenty of "background"  space, and it will grow anywhere, though it does best in a rich, moist soil. Its natural habitat is over the whole of Europe, North Africa, and Asia Minor. The flowers are bright yellow, varying considerably in colour, size, and height, as would be expected where distribution is over so wide an area.

There is an American representative of the section in versicolor (syn. Virginica). This is the American "Water Flag," and although quite different from Pseudacorus, it has much in common with that species. Versicolor grows wild from Hudson Bay in the North to the Gulf of Mexico in the South. The usual colour is a pale blue purple, though there is a natural red-purple form called kermesina. Both are very desirable waterside subjects, and at easy to grow. Culture is the same as for other members of the section - a damp, lime free soil, rich in humus.
Botanical affinities between the four species of the laevigata section suggests that inter-crossing should not be a difficult matter, but with the possible exception of Rose Queen, no hybrid is known. In inter-crossing it is necessary to de-antherise the seed bearer as soon as the flower opens, as the flowers of all the members of the section are so constructed that self fertilisation is naturally effected.

CRESTED IRISES OF EVANSIA SECTION

Some Lesser Known Irises 

  PART III

CRESTED IRISES OF EVANSIA SECTION

By Miss J. Burgess, Waikanae.

THE NEW ZEALAND SMALLHOLDER, April 16th, 1935.

 Although one or two of the crested irises are known to the New Zealand gardener, there are several species of this interesting section which are rarely if ever seen in this country. It is generally believed that the Iris genus is divided into two divisions, the bearded and the beardless irises. However, there is a group intermediate between these two divisions, a group that is distinguished by possessing a crest in place of a beard on the fall. All the members of this group are rhizomatous rooted, though the different species vary greatly in the shape and size of the flowers and the height to which the plant grows.

The name Evansia was given to the section in 1812, in honour of a Mr Thomas Evans, of the India House, who had introduced Japonica into England a year or two previously. Japonica, which has two synonyms, fimbriata and chinensis, is the best known member of the crested section. It is a native of China and Japan. In England, Japonica can only be grown and flowered successfully in a greenhouse, but in many parts of New Zealand it has proved almost hardy. It will stand quite a heavy frost as far as the foliage is concerned, but I frost of six or more degrees may catch the flower spike before it emerges from the foliage, so that in most districts some slight protection is advisable towards the end of winter when the buds are forming. A lover of lime and a sunny aspect, this species is by no means difficult of culture. The flowers are a delicate and delightful shade of lavender blue, lightened by a light freckling of gold at the throat. They are borne on gracefully branched stems about two feet in height. Each stem carries a large number of buds, which give a succession of bloom over several weeks. There is an entirely hardy form called Ledger's variety which has slightly larger flowers of nearly the same shade of lavender blue. Both Japonica and this hardy form flower in the early spring.

From the Himalayas comes Millesii, named after Mr Frank Miles, who introduced it into cultivation about 1880. It is a distinctly handsome Iris, and the tallest of this section. Perfectly hardy and easily grown, it requires like Japonica, lime and a sunny position. The flowers, which appear at the end of October, are borne on 3ft. well branched stems, which continue to develop flower after flower over a period of eight or ten weeks, a surprising long period for a single species. The flowers themselves are about 3 inches across, and are a delicate lilac, spotted on the fall with a deeper shade of the same colour. The foliage which is extremely ornamental, is a clear light green which shows up as a distinct contrast among most other plants.

Better known, perhaps, is tectorum, from China and Japan. The Chinese grow this Iris on the roofs of their houses, whence the name tectorum and the popular name of "roof garden Iris". It was introduced in 1874 by Mr William Bull. The flowers which are flattened, as in Iris Kaempferi, are from 3 to 5 inches across, and are borne on 12 inch stems, each of which carries from two to three flowers. The colour is a deep lavender blue, with a conspicuous white crest on the fall.
There is also a really charming white form of tectorum whose purity is enhanced by a soft yellow signal patch. This white form sets seed readily and comes to colour. Both the blue and white tectorum are perfectly hardy, and the culture is the same as for japonica and milesii.
A dainty little Iris of less easy culture is gracilipes, from Northern Japan, where it grows on wooded slopes with a cool aspect, and in loose vegetable soil, in much the same conditions in which primroses thrive. This and speculatrix, about which later little is yet known, are the only grassy leaved species of the section. They are delicately fringed flowers of gracilipes, which are borne on 6 inch stems, are a pale lilac pink, lightly touched with orange on the fall.

There are two American representatives of the Evansia section, cristata and its Canadian form, lacustris. These are dainty little miniatures, cristata being 4 inches, and lacustris two inches in height. The flowers are lilac, and in cristata about one and a half inches across, in lacustris one inch. Culture for both is the same as for gracilipes. Cristata, comes from the Southern States of North America.

(Update Notes;  The only evasia that has no crest I.tenuis was transferred into the genus Evansia, Lenz, 1959, originally classed as a Pacific coast iris, its closely related to cristata and lacustris and also needs to be included in this American group. Also I. speculatrix has been removed from the evansia section. TJ.)

IRIS SPURIA

 Some Lesser Known Irises
  PART II

IRIS SPURIA
By Miss J. Burgess, Waikanae.
THE NEW ZEALAND SMALLHOLDER, March 16th, 1935.

The Spuria group of irises is for the most part tall growing, and prefers a moist, loamy soil. With but one or two exceptions they object to the presence of lime. However, in common with most other irises, they are really adaptable, and will do quite well and flower freely and good guard soil, provided they can be supplied with water during the main growing season, which is from the blooming in November and December until April. Moving and dividing is best carried out immediately after flowering.
The tall species of this group have long, sword shaped leaves, and are very handsome and exotic in effect when clumps are grown in their correct setting. They look at their best growing by the waterside or an a low lying swampy area. To get the best effect they should be grown in spacious surroundings, where one may stand away from them and view them in combination with other waterside growth. The colour range is through many shades of blue and purple to white, primrose, sulphur, and golden yellow. The flowers are produced on tall, stiffly upright stems, usually bearing several lateral branches, which are, however, held erect close to the main stem, thereby giving the appearance of a single head of bloom. In shape the flowers themselves bear are really strong resemblance to the Xipion (English/ Dutch) or Spanish Iris group.
There is no one form to which the name Spuria can be specially applied. Many differing forms collected from Spain, France, Germany, Austria, Hungary, and through Asia to the Kashmir district have been given the specific name during the last 400 years. The section has been for many years and cultivation, and the botanist, Clusius, mentions in his horticultural work, published in the 16th century, that he had found the form to which he had given the name Spuria growing wild near Oppenheim on the Rhine in 1563.
It is very difficult to distinguish between the various forms, though many have been given varietal rank. They all agree in having blue or purple flowers of varying depth of colour, relieved more less by white or creamy yellow markings at the base of the falls. The European forms are fairly dwarf, 1 foot to 2 feet in height, but the form usually catalogue by nurseryman as Spuria was collected at Sringar, in Kashmir,and grows to a height of 3 to 4 feet.
Sintenisii, a species belonging to the Spuria group, is distributed through southern Italy, the Balkans, and Turkey. It is a dainty little thing of rich, royal purple, with decided white veining on the blade of the falls.
Sintenisii is sometimes confused with Graminea, a species from central Europe. Graminea is a fascinating little Iris some 15 inches in height. Standards and falls are a bright China blue, with the style arms dealing a decided contrast of red-purple. This species is distinguished by its sweet scent, which resembles strongly the centre of a ripe peach or apricots.
One of the tallest irises of the group, and the easiest to grow in a section notably easy, is Ochroleuca, which grows to a height of 5 feet, and bears large stiff white flowers, very pure in effect, with a gold signal patch on the fall. It has been sent out by nurseryman even so recently as 15 years ago, under its old synonyms of Gigantea and Orientalis. It is a native of Asia Minor.
Monnieri is the same height as Ochroleuca,but is somewhat larger in the flower and the colour is a bright yellow. The habit of Monnieri is not known. It was found in the garden of Mons. Lemonnier, of Versailles, where it was believed to have come from Rhodes or Crete. It has not however, been collected since by botanists in those islands. Dykes, in 'The Genus Iris', doubts whether it is entitled to specific rank, rather inclining to the belief that it, with Ochroleuca, is merely a natural colour variety of some form of Spuria.
Aurea is a native of Kashmir, and has flowers of a slightly different shape from the foregoing. The colour is richest golden yellow, and the flowers are borne on 3 foot stems. It is one of the last of the group to flower.
There are some very fine hybrids of these tall spurias, outstanding varieties being 'Shelford Giant', 'Monspur', and 'Monaurea'. They were raised by Sir Michael Foster in his garden at Shelford.

Footnote
It is interesting to note that the author Miss J. Burgess [Jean Stevens] refers above to Orientalis as a synonym for Ochroleuca which at the time of publication (1935) was most likely correct but today because the name I.ochroleuca unfortunately came later than I.orientalis the reverse applies and under the International Rules of Nomenclature it is now referenced as, I.orientalis Miller (Syn. I.ochroleuca).
Also generally the practice of dividing is done nowadays at the start of the Autumn Rain.

Tall Bearded Heirloom Iris "NEW DAWN"

HAPPY NEW YEAR TO YOU ALL!!!
I thought this an appropriately named heirloom iris to celebrate the New Year.

NEW DAWN' is an Iris with star quality in both parentage and colouration. In 1928 Emily Jean Burgess (later Jean Stevens) somehow crossed the early flowering William Rickatson Dykes-bred, pearly white coloured 'Moonlight' with Sir Arthur Horts' late flowering purple bi-colour iris ‘Hermione’.  The resultant seedling with no description of colour or form was only ever labelled  'E97' and in 1931 Jean  crossed it with Arthur Bliss’s 'Mrs Valerie West' to produce the clean and finely textured primrose yellow cultivar. On its release in England, 'New Dawn' was often compared with 'Helios' which in the early 1930s, along with W .R. Dykes were the standard-bearers for yellow irises.  These had clean yellow standards with yellow falls that were reticulated, generally in a tone of light purple brown.'New Dawn' was a triumph in light yellow breeding because of its clean colouration on the standards and falls and was without doubt at least the equal to the introductions of the late 1930s in the same colour range, such as 'Happy Days', 'Golden Bear','Lady Paramount', and 'Primrose'. Jean had a firm opinion on striation or reticulation and often noted that it was a fault in Irises, as its presence almost invariably detracted from the purity of the colour tone.  She also used the term 'rough' in reference to veining.
'New Dawn' is an Iris with vigour, large numbers of bloom and has excellent increase, outperforming most of the more modern Irises. The large buds of intense primrose are a feature in themselves. Found growing in a garden in Carterton, my plants were given to me by the garden owner who had surplus plants established over the fence, growing alongside the railway line. Vigour is as good as 'Magnolia". Its the pollen parent to the New Zealand heirloom white iris 'Wychnor' featured on the blog last November.
Last years bloom season (2011) it was no match for the 140 km an hour winds that attacked our gardens in October, the blooms stalks just fell over, but all I had to do was stake the very numerous stalks and  'New Dawn' just continued flowering through the season for another four weeks  -  it was just like nothing had happened. The above photo was taken after the storms

The Iris Yearbook 1937 (BIS)
Seedlings Seen, R.E.S.Spender writes
New Dawn (Stevens)-- A seedling raised in New Zealand. It is a splendid grower, and is much improved Helios in colour,a pale lemon-yellow without streaks, and a fine shapely flower of real merit. It is I am told a Moonlight -Valerie West derivative.

The Iris Yearbook 1940 (BIS)
Some promising New Zealand Irises, Mr G P Baker writes
New Dawn, a straw coloured white, was particularly strong with three very massive flowering stems. The others were not quite of the same substance

The Iris Yearbook 1942 (BIS)
Discursions of an Iris Breeder, R. E. S.Spender writes; [Ref 1]
"The truth is Golden Hind (and its numerous descendants) has now given me all the yellows I could want or even find room for and I for one shall not attempt any further crosses with what is nevertheless the best parent for yellows I have yet come across, so just why it should be so, in view of its distinctly plebeian parentage, is one of those mysteries of  hereditary which is impossible to fathom.
About the same time that I started on these crosses I received the big yellowish-cream New Zealander, New Dawn from its raiser Mrs W. R. Stevens. New Dawn is (Moonlight x Hermione) X Mrs Valerie West, and is therefore, I should judge-assuming Moonlight to have had a good deal to do with the production of W.R. Dykes-not wholly unconnected with Golden Hind. No two yellows could be much more dissimilar, however, in build, and I should certainly not have used it except for lack of other material. It too proved an easy as well as valuable seed parent, though, unlike Golden Hind, it is not apt to produce the shapeliest of seedlings. But they have substance, they are always large and stout growers, and now and then one may get a perfect seedling from it. Crossed with Purple Dusk, it produced a really superb white, spangled with a gold dust, which is different from any other I know. I should think it may prove one of the best seed-parents now available although a good many of the seedlings from it may be inferior in form. But Mr Long, who has used Valerie West far more than I have may very likely have a good reason to challenge that."

NEW DAWN (Stevens)
Another outstanding seedling of our own raising which already has been highly commented upon in England. Of particularly heavy substance and finest texture, this Iris will stand up to a adverse weather conditions better than any variety we know. It has a vigorous constitution and a long flowering period. The large well formed flowers are a clear lemon entirely unveined. One leading English Iris critic has described New Dawn as "Superb in every respect" 3ft.
