Heirloom Tall Bearded Iris "CATERINA"

Perhaps one of my great finds in New Zealand this year is an Heirloom Iris of significant historical importance growing in an Auckland garden.

Sir Michael Foster is justly looked up to as the pioneer and founder of the modern cult and cultivation of the Iris, and in 1888 he crossed I. pallida with I. cypriana, both of these irises at the time being considered collected wild species. The result, a selected seedling 'Caterina' (named after the Queen of Cyprus) was introduced. It was one of the first tetraploid hybrids, and proved to be invaluable for introducing plant size, vigour, plants with taller well-branched stems, and larger flowers to the world of tall bearded iris breeding. The hybrid vigour of this hand-cross produced seedlings that in comparison to the predominant diploids of the day were spectacular. Many of the early pioneers of tall bearded iris breeding, including Amos Perry, Geoffrey Pilkington, Sir Arthur Hort, George Yeld, Louis Dennis, Grace Sturtevant, B. Y Morrison, William H Mohr, the Sass Brothers, Edward Essig used 'Caterina' in their breeding, making it an ancestor of some of the best irises. As an example, William Mohr used 'Caterina' in a cross with I. mesopotamica to raise a seedling he named 'Argentina' (1923) which he then crossed to 'Conquistador', (1923) (Juniata X I. mesopotamica) to produce 'Purissima' (1927) . This was considered to be one of the all time greats in the colour white and was used extensively in hybridising. When 'Purissima' was crossed with 'Thais' it passed on its genetics plus its pure white colour to the outstanding tall bearded iris 'Snow Flurry', (1939). Seventy years ago this must have seemed like a miracle in outstanding hybridisation. When I sent the above photo to Phil Edinger for conformation of its identity, his informative reply was , “CATERINA! And a very nice shot of her, too!! One almost-diagnostic feature is the stalk. Often, as it elongates, the upper part will bend over. Sometimes it remains that way to some extent, with the terminal blossom at an odd angle. More frequently, though, the stalk will recover from the bend and grow upright but leave a bend or "crook" in the stem. The "official" description in AIS Bulletin 6 notes "stalk apt to be flexuous."

The Dean lris Gardens, Growers and Importers of Choice Iris, 1914 Catalog, Moneta, California.
THE late Sir Michael Foster, of England, devoted many years to the study of the Iris, collecting from all parts of the world wherever they are to be found-and also produced a large number of hybrids. Had he been trying to produce an Iris among his hybrids, particularly adapted to our climate, he could not have done better than when he gave us Caterina. It is a queen among Irises beautiful for any climate.

'We quote from two of the leading Iris growers of England regarding this Iris.'

"A lovely hybrid raised by the late Sir Michael Foster, from I.Cypriana and I. Pallida; the flowers are of great size and borne on long, stout branching stems, standards light clear blue, falls soft lilac-blue, delicately fragrant, 4½ feet. Award of Merit R.H.S."

"A very pretty hybrid, one of the very best of the late Sir Michael Foster's pets; a cross between Cypriana X Pallida, having large, conspicuous pale mauve flowers, with a brownish marking at base and a very conspicuous yellow beard. A.M., R.H.S."

The foliage being persistent throughout the year, the plant is ornamental at all times, with its broad leaves some two feet tall. The growth of the plant being checked a part of the year in colder climates, no doubt the blooming period is not as long as it is with us. It comes into bloom here about the 6th of April, and with proper care remains in bloom for two months and more. Our own stock, although divided last year, has not been without bloom for three months and is still making new flowering stems at this writing. The flowers are borne on branching stems, some four feet tall; most of the stems produce from fifteen to twenty blossoms, often five flowers being open on a stem at a time. The flowers measure 5½ inches from top of standards to bottom of falls. The plants do not throw up a quantity of flowering stems simultaneously, as many Irises of this class do, but instead seem to court our attention and admiration, by modestly extending their blooming period over such a long season.
We can confidently recommend it to those who have room for but a few plants and want something choice, and also that will give increased pleasure from year to year, as well as to those with more ample space, and who can perhaps afford to plant more liberally of it. Our stock is guaranteed true to name. The price at which this Iris is held, both in Europe and by the growers in the Eastern States who list it, proves that its worth is appreciated. The grower from whom we secured our stock in England writes us that this plant is getting very scarce, and many forms are being sold, both in England and elsewhere, as Caterina. For this reason, and the fact that the stock does not multiply as rapidly as that of some of the more common bearded varieties, the price will not be much reduced for some time to come.

AIS Bulletin #6 October 1922, Description of Varieties Part 1
CATERINA 8.9 (19)
Self, V. (1). Foster, 1909
Brief. Bluish lavender the falls slightly flushed lavender violet; S. fluted, tips touching; F. drooping; stalk low and well-branched; growth very variable; to 4 ft.
Details. Haft reticulations broad, widely spaced, brownish; beard white.yellow tip; stalk apt to be flexuous.
Remarks. A. M. R. H. S., 1907. Very fine in California but in the North it requires the most thoro drainage as it is subject to rot and winter killing.

The Iris Society (BIS) Bulletin No.2 May, 1925 'Sir Michael Foster and his Irises'.
 Sir Arthur Hort discussed his good friend’s work, and wrote “Foster gave me a bit of his original plant of Cypriana a name to which there are several pretenders. It has if I remember right (for I fear it is no more) as a rather weak stem and a large floppy red-purple flower; like Mesopotamica its best use is perhaps for hybridising. From it Foster raised several fine things. The finest and the best known are Caterina and Lady Foster, the later named I think by Mr Wallace after Sir Michaels death; Mr Wallace and I both I believe, first saw it at Shelford the same day. Caterina well illustrates the wisdom of seeding from a good hybrid.”
Sir Arthur Hort also made the following observation in the same article in regards to I. pallida , “Foster's collected pallida forms are very numerous ; he showed me once a bed of thirty arranged in order of stature and exhibiting what he called, 'The degeneration of pallida.'”

W R Dykes 'Handbook of Garden Irises' published 1924 page 226
'Caterina (48ins., Foster, 1909), pale lavender, flowers large but a weak stem, often unable to hold itself erect;” and from page 232, 'In this country little had been done before 1900 to raise garden hybrids on a large scale. Foster had made a few experiments with new introductions and obtained such good hybrids as Caterina and Miss Willmott but they were produced rather as the result of other enquiries and not as an end in themselves'.

A Major Hat Tip to Audrey McCarrison for growing an iris she loves, and also to Phil Edinger for the interaction of thoughts and discussions concerning 'Caterina'. Perhaps one of the great outcomes when finding historic irises is the sharing of information and the friendships that are formed with those genuinely interested in historic Irises. As referred to above the merits and all the exciting contributions that Snow Flurry" made to the world of modern tall bearded irises will be elaborated in a separate post at a later date.
