Top Ten Favorite Irises in New Zealand

In the New Zealand Iris Society popularity poll in 1996, there were actually twelve on the "Top Ten" list. This was because eight irises tied for 5 th place, each receiving the same number of points. Tall bearded irises remained the most popular type of iris in New Zealand, receiving 35% of all votes cast. The cultivars that ended up getting the highest number of voting points, however, represent a great diversity of type. So here were the most popular irises in New Zealand last year:

 Rank

 Name

 Hybridizer & Introduction Yr

  Type of Iris

 1.

 Butter and Sugar  McEwen, 77  Siberian

 2.

Windrose  Blyth, 89/90  SDB

 3.

 Silverado  Schreiner's, 87  TB

 4.

 Kirigamine  Unregistered  Setosa

 5.

 Loudmouth  Rich, 70  AB
   Ingleside  R. Harvey, 91  TB
   Pure Allure  Richie, 87  SDB
   Harpswell Haze  McEwen, 77  Siberian
   Crown Sterling  Moldovan, 72  TB
   Silver Edge  McEwen, 74  Siberian
   Lucy's Blue Silk  Delaney, 86/87  IB
   Bumblebee Deelite  Norrick, 86  MTB
The Iris setosa cultivar "Kirigamine" is one of the loveliest I grow. It really should be registered. "Kirigamine" comes from Japan and is named for a famous Japanese mountain. The name means "foggy peak".

The British Iris Society Species Group and an Interesting Iris Species

The Species Group of the British Iris Society has an interesting Bulletin, and I always look forward to its arrival in the mail. For overseas members, the dues are ten pounds for three years. The dues may be submitted to the Treasurer, Mr. Charles Lyte, Carters Corner Place, Cowbeech Rd, nr. Hailsham, East Sussex, BN27 4HX, England. In the February 1997 issue of the Bulletin, there was an interesting item on an iris species not particularly well-known in North America by Mr. Chris Rose, who has been editor for the Bulletin.

In Brian Mathew's The Iris (London, 1989), the author states that "An unforgettable sight for me when I visited Iran one year was a scattering of clumps of this iris [Iris imbricata] amid red oriental poppies on the scree slopes of the high Elburz." For a long time botanists confused the yellow-flowered Iris imbricata with FLAVESCENS (or I. flavescens as it was called in former times). This species is native to Iran and northward into eastern Transcaucasia. Mr. Rose's article describes his success in growing this species from seed:

"Three seeds of Iris imbricata, Item 7 from the BIS 1990/1 seed distribution, recorded as originating from a French source, were obtained in 1991. "the seeds were soaked and 'peeled', then soaked for several days more--during which time they were rinsed every day or two. I found fingernails were the most easily used tools for getting the seed coat off. Don't worry if you've never done this before, unless the seed inside is rotten and unviable it is generally hard enough not to be damaged by doing this". By these processes the physical barrier of the seed coat and its associated chemical inhibitors of germination are removed as far as is possible with the aim of making it more rapid and even.
"The seeds were sown on 10/2/1991 in a predominantly soil-basedÖwell-drained compost in a plastic pot. They were covered to a depth of 2-3mmÖ.The pot was initially kept in an unheated conservatory and put outside in a sunny place on sunny days. All 3 seeds geminatedÖ.The second seedling to appear never really got going and rotted off, which led me to reduce the watering [of the remaining two seedlings].
"The two remaining ones were pricked out into standard-depth 6" plastic pots on 11/6/92Ö.Both flowered for the first time in April 1994Ö.A note of April 22nd extolled the virtues of what I regarded as the ëclassically shaped' flowers with ëproperly falling and superbly angled falls'Ö."

It was thought that this description of the experience of growing I. imbricata from seed might be useful to others who might like to try it. This could be quite beneficial considering that I. imbricata has not been widely used in breeding garden irises.

Festival Crown Plate Awarded to Dora Sparrow

The Festival Crown Plate, presented to the New Zealand Iris Society by Anne Blanco White, is awarded by that society for meritorious service. In 1996, this award went to Dora Sparrow, one of the founding members of the New Zealand Iris Society. Ms Sparrow has held many offices in various iris societies and is widely respected for her expertise in all aspects iris growing, hybridizing and showing. She has hybridized various types of irises, and in particular is known for her work with Pacific Coast Natives. Over the years she has imported many irises to New Zealand for donation to the Christchurch Botanic Garden and other public gardens. A long-time member of AIS, we congratulate Dora on the well-deserved honors bestowed upon her.

Update on the Iris Society of Southern Africa

The new Chairman of the Iris Society of Southern Africa, AndrË Buitendag, has advised me that the annual dues in that society for overseas members are $10.00, plus $2.00 if you wish to receive the Bulletin by airmail. Having had a number of items damaged or lost when surface mail was used, airmail is definitely recommended. AndrË also advised that the many friends of Graeme Morgan may correspond with him at this address: P.O. Box 71, Sterkstroom 5425, South Africa.

Three New Books on Irises from Europe

During my trip to England this spring I was able to obtain three recently published books on irises, all quite excellent for the material covered. If you do not have another means of acquiring these books, most book dealers will special order them for you.

The first book I will mention is in German, and is the work of a superb horticulturist, Susanne Weber. For fifty years, Susanne was the right-hand of Grafin Zeppelin at her famous nursery. Her book is Iris: Die besten Arten und Sorten f¸r den Garden (Verlag Eugen Ulmer GmbH & Co, Stuttgart, 1997). The publisher's address is Wollgrasweg 41, 70599 Stuttgart (Hohenheim), Germany. This is a lovely book with 107 beautiful color pictures. Even though I do not read German, I much enjoy looking through this book. It is a book intended for the gardener, not the botanist or the specialist; but the botanist and specialist will find much of interest. It has some excellent garden plans incorporating irises, and a list of European and American nurseries where one can obtain irises.

A Guide to Species Irises, Their Identification and Cultivation (Cambridge University Press, Cambridge, 1997) was produced under the auspices of the The Species Group of the British Iris Society. A number of iris authorities contributed to this monumental work, and I was fortunate enough to get the autographs of several of them in my treasured copy, i.e. Anne Banco White, Brian Mathew, Nigel Service and Peter Maynard. (Now I shall have to get Jim Waddick to sign it also, since he wrote the section on Iris pariensis.) There are a nice selection of color plates and some excellent maps by William R. Killens and line drawings by Christabel King. This is the definitive modern monograph on the subject. No one who wants to be an iris "expert" can be without this wonderful book.

The third book I found this spring is The Gardener's Guide to Growing Irises by Geoff Stebbings. This book was published jointly this year by David & Charles Publishers (UK) and Timber Press (USA). Geoff Stubbings is currently Features Editor of the Royal Horticultural Society's journal The Garden. With this sort of credential it is surely redundant to say that this book on irises is very well written. There are chapters on all types of irises and such topics as hybridizing, using irises as cut flowers, landscaping with irises and cultivation. This book has many useful appendices and many attractive color plates. A lovely work.

Hadlow, 1997

What can I say? For those of us fortunate enough to attend the 75 th anniversary fete of the British Iris Society at Hadlow in Kent, the garden of England, it was a marvelous experience. The tours were educational and delightful. The programs arranged by the British Iris Society were first-rate. The courtesies and kindness of our hosts were beyond any reasonable expectation. Most of us who attended this convention combined our attendance with a visit to the Chelsea flower show, about which I will only say that I now know what paradise must be.

Everyone was apologetic because a late freeze had damaged many irises and delayed bloom beyond normal expectations. But there were many irises to be seen in glorious gardens. I was fortunate enough to take the tour to Wisley with the learned Ray Jeffs as a guide. Many of the American median irises on trial there were doing quite well, and Dick Sparling's beautiful white border bearded iris ALLENDALE (1989) was near perfection.

The work that the Kent Group put into the planning and conduct of this convention was thoroughly evident. Thelma Naylor who served as registrar deserves a special thank you. The efforts she made to assist overseas visitors were extraordinary. Berney and Alice Baughen surely deserve a gold medal for their many contributions. To the fine people in the Kent Group who worked on this affair: "Thank you!" To the British Iris Society: "Happy 75 th Birthday!"
