Visits and important events a t Shamrock in 2013 THE APJHN PRIZE www.arpjhn.net We were very proud and pleased to be awarded a prize by the Association des Parcs et Jardins de Haute-Normandie. All members of our society who have contributed in one way or another to this recognition must be conscious of what an honour it is to receive this prestigious award. It comes as a culmination of the support that this regional association has shown us in recent years, and we are most grateful for it. VISIT BY THE AMERICAN HYRANGEA SOCIETY, ATLANTA www.americanhydrangeasociety.org Going beyond the moral and financial support that the AHS showed us during our trip to Atlanta in April 2013, on 19 July we had the great pleasure of receiving a visit by members led by the society's president Sandy Jones. This year has therefore been an opportunity to strengthen the ties between our societies, who have been working together since 2001, thanks to Ozzie Johnson's unfailing friendship and Jean Astrop's generous hospitality. We were able to see Elizabeth Dean and Gene Griffith again (Wilkerson Mill Gardens), and discover the nursery of Scott McMahan (Gardenhood), an explorer we would also like to thank for his support. Note: Shamrock participated modestly in financing a Seed Collecting Trip to Vietnam 2013 with Ozzie Johnson. GROUP VISIT ORGANISED BY LUC NOËL [email protected] (presenter of the Belgian RTBF TV programme “Jardin-jardinier” who had produced a TV report about Shamrock in 2012 : www.youtube/com/user/jardinjardinier). SPEECH BY LYNDEN B. MILLER (4 July, Luneray) This great American landscape gardener, who transformed many of the public parks and gardens in New York City, told us about her adventure. You can read her book: Parks, Plants & People (W. W. Norton & Company 2009), and see her talking about her philosophy and message at : www.youtube.com/watch?v=xItapO_NJpg 2 New members 2013 We are pleased to welcome the following new members: Elisabeth BELLELGO Jacques BEMBERG (CH) Ghislaine & Jean-Pierre CRESCENTINI Anne-Marie DEL MARMOL Dominique EVRARD Marie-Claire GIRARDIN Gonzalo GONZALES (ES) Christine GUIGON Arnauld GUILLY Bob HOWARD (CN) Bernie & Janique BOUTRY Jean-Baptiste LEROY Marie-Madeleine BARLE Clothilde MARCHAND Dr. Jean-Claude MARZEC Joël MORDELET Sandrine & Philippe MOUTON Louis & Monnica ORIET Virginie REICHARDT Véronique SCHMIT Nadia SOUABRIA Roland & Sylvie STUTZMAN Marie-Odile THOUVENIN Elisabeth & Nicolas TRUELLE Dominique & Corinne VINCENS The Lemoines, breeders of genius Jean-François Gonot R/*2#d-5.64#W*<6-2*#9*5-9*9#.6#1*56<*#0#?049*2*4#A-=*#/-+#:0./*4,#/*#B*2.#6::#.6 A*042#/-+#.409*#0+#02#0KK4*2.-5*D#>*#:6729#67.#0167.#404*#KA02.#+K*5-*+#029#./* +*54*.+#6:#14**9-2?#B-./#./*#?4*0.*+.#%746K*02#/64.-57A.740A#+K*5-0A-+.+,#K4-<04-A3 d02#>67..*,#./*#-2.*420.-620AA3#4*26B2*9#e*A?-02#/64.-57A.74-+.D# S2#LO^M,#/*#:6729*9#/-+#:-4+.#56<K023#-2#c0253#HW6440-2*P#B/*4*#0.#:-4+.#/*#+6A9 6./*4#14**9*4+;#54*0.-62+#029#*_6.-5#KA02.+,#029#./*2#0#A-..A*#A0.*4#/-+#6B2#54*0G .-62+D#X/*#56<K023;+#*_K02+-62#A*9#.6#0#:-4+.#4*A650.-62#-2#LOJID#X/*#9*:*0.#6:#./* LON"#840256GU47++-02#B04#+.-<7A0.*9#./*#74102#*_K02+-62#6:#c0253,#:645-2?

It was the lime trees in the western alley at the collection that bore the brunt of the storm, with five of them blown down. The job of clearing and making everything safe took several weeks, but thanks to everyone's efforts, it was possible to keep the collection open to visitors (see photo on page 4). There remained the major concern of the excessive growth of the hazels, birches and hornbeams in Green Dragon Wood, which were depriving the hydrangeas of the light they desperately needed in order to grow. This was particularly true for the H. aspera at the top and some of the H. serrata at the bottom of the wood. There were also some Paulownias in the original part of the collection which had been planted too close together and needed to be cut back. This was the task of the weekend of 15/16 November when no fewer than 11 members worked hard to create shafts of light, cutting and storing the logs, while the leafy branches were brought down and dealt with separately. It is well worth repeating once again that without the generous help of Christiane Scanff and Jean-Marie Rouet, the Shamrock collection would not look nearly as good as it does today, since they began their regular and systematic work here three-years ago, with the goal of thoroughly weeding all the beds. CURRENT WORK Christiane Rouet, Robert, Hervé Lepetit, Madeleine Alves & Daniel Kuszak Jean-Marie Rouet J.-P Péan, Pierre Courquin, Pierre Le Clair Daniel Kuzsac & André Dieval Daniel Kuszak Christiane Le Scanff 8 More work in the Green Dragon Wood is planned for March, removing stumps to prevent the spread of honey fungus. We will also attempt to remove an ash tree whose rather too greedy roots are threatening new beds of H. serrata at the bottom of the wood. On the “crop circle”, with the agreement of the nurseries concerned, some cultivars will be replaced by new varieties to help continue the experimental work that the Shamrock collection has now been carrying out in this location for 3 years.

All this is a pleasure for our eyes, but for theirs too: insects of all kinds cannot resist them.The “browsers” are legion: honey bees, bumble bees, hoverflies, butterflies, and all the rest, revel in the nectar. Some insects find refuge in the flowers, others, predators, use them as a hideout.They are a real gift for this miniature living world. Evocative names pay homage to some of these insects: for Hydrangea paniculata 'Papillon' ('butterfly'), there is no need to comment. For the “Map” butterfly Araschnia Levana, which gives its name to a hydrangea, (H. paniculata 'Levana'), the insect is a faithful admirer of this plant The scent of some hydrangeas fills the atmosphere and attracts all these little creatures: a pleasure for our gardens and our beehives; bees abound on the species Hydrangea aspera, villosa, Kawakamii and Sargentiana, which all contain wholesome food for these guests. The late flowering of these species is a vital advantage for insects; a real godsend for them before they have to face the winter. How can we remain indifferent to this wonderful show? Nature is so beautiful and generous, and a joy for all of us, large and small, whether we have eight, six, four or only two legs!

Sargentiana 12 Philipp Franz Balthazar von Siebold Marion & Matthias Riedel (Continued from the article published in nos. 23 & 24) It has rightly been said that among German scientists, Siebold is one of the most remarkable personalities. His contribution to the introduction of hydrangeas to Europe constitutes a mere fraction of his immense work. Siebold came from a family of doctors in Wurzburg. He studied medicine, and then managed to enter the service of Holland through a friend of his father's, Christian Gottfried Nees von Esenbeck, president of the Leopoldina . He arrived in Batavia in 1823 with the Dutch East India Company and from there, the same year, went on to Japan where he was appointed chief physician on the artificial island of Deshima and also given responsibility for research into natural sciences. Responding to an appeal by a researcher into medicinal plants, he began daily excursions to investigate the plant and animal world. To this end he bought a house in the valley of Narutaki which he turned into a kind of “University” for his Japanese friends. At this site but also around his house on the island of Deshima, he created a botanical garden. Soon 1400 species were being grown. On the economic front, Siebold devised an original and efficient way of transporting the seeds of tea plants (in ferruginous clay) which was to form the basis for extensive plantations on the island of Java. But Siebold's main purpose was to describe the largest possible number of previously unknown Japanese plants following the Linnaean classification system. His Japanese students were given the task of constantly adding to this collection as much as possible. To continue with this purpose, Siebold had an absolute need to travel in the direction of Edo. His collecting fever and inventiveness led him to find an original way to continue: although confined by the authorities to his home, and only a few weeks away from his departure, he was still keen to increase his collection, so he asked for permission to keep a goat for milk: in this way his students could smuggle in precious plants in the bales of hay used as food for this goat . Suspected of espionage and imprisoned, Siebold was allowed to leave Japan in 1829. He was able to gather 1200 species of plants (of which 260 survived the sea voyage) and a herbarium of 12,000 dried specimens. One year later, back in Holland, Siebold received unlimited leave from King Willem I to look after his collections. His first shipment of plants to the Netherlands in 1829, accompanied by his illustrator K.H. de Villeneuve, had been destined by contract for the Leiden Botanical Garden, but there were no hydrangeas in this shipment. A second shipment arrived in Antwerp and was dispatched to Brussels (for herbarium specimens) and Ghent (for living plants). Among the 260 living plants, there was a Hydrangea serrata (Thunb. 'Syringe' Rosalba '(Siebold described it under the name of H. japonica flor. Roseis). During the disruption associated with the Belgian Revolution, although he was certainly able to transport his herbarium to Holland, the living plants had to remain in Ghent. But from as early as 1841, Siebold was on several occasions sent specimens of these plants grown by Donckelaer, the gardener of the Leuven Jardin des Plantes. Then in 1843 there was a new arrival in Leiden of Japanese plants from the Botanical Garden of Buitenzorg in Java, and among the 28 taxa that survived the sea voyage, there was, this time, a Hydrangea macrophylla (Thunb) Seringe, with flat inflorescences, to which Siebold gave the name H. aslsaï. The majority of the hydrangeas described by Siebold and cited in this article came from his second trip to Japan from 1859 to 1861, including, finally, the famous 'Otaksa', with blue flowers. 1: the German Academy of Sciences. 2: the same story is attributed to Thunberg, who was allowed much less freedom of movement than Siebold during the six years of his stay in Japan 13 Philipp Franz Balthazar von Siebold 14 Philipp Franz Balthazar von Siebold Siebold, with the intention of exploiting his collections in Holland, bought a house in the vicinity of Leiden, which he called 'Nippon'. There he created a garden of acclimatization where he installed his treasures, including the blue hydrangea 'Otaksa', which caused a sensation. His collaboration with Joseph Gerhard Zuccarini (17971848) on his return from his first trip was of great importance botanically. The latter was Curator of the Munich Botanical Garden, a systematic botanist, and a student of Siebold's acquaintance Nees von Esenbeck. Zuccarini based his work on Siebold's collections, supplemented by other plants sent by Heinrich Bürgers, culminating in the publication of the “Flora Japonica”. It contains the following hydrangeas: H. Azisai (now H. macrophylla 'Yodogama'), H. 'Otaksa' (now H. macrophylla 'Otaksa'), H. japonica (now H. serrata ssp japonica), H. petiolaris (unchanged), H. belzonii (a species that is now lost), H. acuminata (now H. serrata 'Acuminata'), H. thunbergii (now H. serrata 'Thunbergii'), H. stellata (now H. serrata 'Stellata'), H. cordifolia (now H. petiolaris 'Cordifolia'), H. virens (now H. scandens), H. paniculata (unchanged), H. hirta (unchanged), H. bracteata (now H. petiolaris) , H. involucrata (unchanged) In this way the majority of the East Asian species known today were discovered. Many of them are now known, not under the original species names, but as subspecies or even cultivars. A large part of Siebold's legacy can be found in the National Herbarium in Leiden. It is in fact possible from the descriptions in the Flora Japonica to recognize some of the actual specimens in the herbarium, which was then known as the Royal Herbarium, curated by Karl Ludwig Blume (1796-1862), who in 1826 was still Director of the Buitenzorg Botanical Garden in Java, and therefore a useful partner for Siebold in his research. Since the publication of his work had brought in substantial sums of money, together they founded an “Association for the introduction of animals and useful plants from Japan, Holland and Austria”. Siebold's students and colleagues in Japan gave massive support to this enterprise. Based on this success, a society was founded: “Society for the encouragement of horticulture through the use of Japanese and oriental plants”. This is how a large number of new plants were successfully introduced into European gardens. In the Hortus Botanicus of Leiden which was created in 1587 under the name “Garden of free thinking and belief”, the original plants introduced by Siebold can still be found.

It has white globular (temari) flowers growing all along its branches, which bow gracefully towards the ground. Cultivation in semi-shade does not seem to pose any particular problems. H. 'Trebah Silver' (centre photo): from Trebah Garden (right-hand photo)in Cornwall One of the series of H. macrophylla mutations of the 'Ayesha' type (also called 'Silver Slipper'), we know several other forms: H. 'Edouard Avdeew' and the fine plant bred by Koos et Wilko Hofstede from 'Mathilde Gütges' which they have archly named 'Hopcorn' (to go with 'Homigo', 'Hobergine', etc.). 'Silver Slipper' is a natural mutation discovered in the magnificent Trebah Gardens (http://www.trebahgarden.co.uk) and named on the spot by the Van Gelderens. Like that of a pure H. macrophylla (e.g. 'Otaksa'), its flowering is practically constant until the first frosts. It is still not very widespread and unprotected, which is why we recommend it. H. involucrata (a seedling) (see photo in the article on p. 19) Mark Libert of Ghent University tells us: “This is a selection from Ghent Botanical Garden, noticed for its suckering quality which could qualify it as a ground cover plant. Maurice Foster told me that for him it is the “best” of all the H. involucrata he grows. There is no better possible compliment for a new selection... as far as I'm concerned!” And the appreciation of Maurice himself: “...plant one metre tall, compact and suckering nicely. A very beautiful flower” Note: As this plant originates from a botanical garden, it cannot be commercialised. Growing it is restricted to private collections approved by the original botanical garden. It nevertheless deserves the utmost attention, for purposes of observation, conservation and possibly propagation in the required conditions. 16 letters From Winston Beck : North Carolina State University « I'm doing research on Hydrangea paniculata at North Carolina State University in the US, and I'm trying to track down as many cultivars of the species as possible. So far, Chicago Botanic Gardens has the best collection in the US of H. paniculata with 42 cultivars. Anyhow, access to your list would be very helpful to see what kind of progress I'm making in surveying cultivars of species. As the results come in, I'll be sure to let you know what kinds of results we're getting. We're checking the ploidy of all market-available cultivars, and there are some subsequent projects to do as well ». Merci encore, Winston De Maurice Foster (29 janvier 2014) “The involucratas I grow are as follows - I think you will have them all but if any are of interest, let me know. hortensis, Oshima, sterilis, Handemari, Yohraku, plena, viridescens, Mihara-Kokenoe, Ghent collection (ex Marc) Incidentally there is a form of viridescens at Herkenrode that flowers in the upper leaf axils as well as terminally. I saw it a few years ago but it might be worth checking with Koen that it is a consistent character. Interesting. The ' favorite' is from Ghent BG courtesy of Marc who gave it to me some years ago. By all means use my pics. It is about one metre, compact and quietly suckering. A beautiful flower.” About Hydrangea involucrata Ishii Chitose (Extracts from correspondence with Jean-Pierre Péan) Hello! Here is H. involucrata 'Sterilis' (= f. sterilis HAYASHI) The Japanese identify two types of cultivars: The first has many fertile flowers included in the ball-shaped inflorescence. We call this type of inflorescence "Han-temari", which means “half ball” (see photo opposite). The second type includes very few ornamental flowers (sterile florets); we simply call it "Temari-tama-ajisai". The young stage is more or less flat, and the mature stage is a cluster. Late season inflorescences are sometimes pale pink in colour. I have heard that there is an H. involucrata with virtually no H. involucrata ‘Han-temari’ ornamental flowers, like H. hirta or H. liukiuensis ... but I've never seen such an H. involucrata myself. The advantage of H. involucrata is that they flower on new shoots like H. paniculata (1) and H. arborescens … So I think the new cultivars should be better suited to cold conditions in Europe and the United States. Yet these plants are not so popular yet in the development of new varieties, as are hybrids of H. macrophylla. None of the new H. involucrata varieties are sold in Japan. I have only ever seen them on the Esveld online site: http://www.esveld.nl , where there is an H. involucrata x aspera from Heronswood and also an H. Kawakamii x involucrata. Coastal H. involucrata, such as H. involucrata 'Yôraku' (photo opposite) or 'Mihara Kokonoe' can be planted in a sunny position. In this they have the characteristics of H. macrophylla. Mountain H. involucrata, on the other hand, such as 'Tamakanzashsi' and the original 'Kokonoe' (to which the Latin name of f. plenissima was given by Professor Tuyama) are more akin to the growing conditions of H. serrata. H. involucrata ‘Yoraku’ Some researchers in the horticultural world compare H. involucrata to the Jomon people who were the original inhabitants of Japan throughout its territory. The J_mon were driven out by the Yayoi people who came from the Eurasian continent via the Korean peninsula. Jomon descendants survived only in the northern island (Hokkaido), in the most northerly areas of mainland Japan, and also at the southern end of the island of Kyushu. The J.-P. Péan & Ishii Chitose "Izumo" province is also "Jomon" because the dialect spoken there is the same as that found in the far north of Japan. Their god was persecuted by the goddess "Ise". This goddess "Ise" (Amaterasu O-Mikami) is considered the ancestor of the present imperial family. The Yayoi people would be in the world of hydrangeas what H. serrata and/or macrophylla were for the Jomon people: newcomers, even though they probably derive from each other (Professor Uemachi believes that H. macrophylla are derived from H. serrata). The Jomon people are therefore akin to the Celtic people in Europe who were driven out by the Germanic tribes to the edges of Wales, England, Ireland, Brittany and some coastal areas of Spain and Portugal. Some Celtic populations lived in seclusion in remote mountain areas, as do the mountain H. involucrata. 17 About Hydrangea involucrata H. involucrata 'Yôraku', 'Mihara Kokonoe' or ‘Kokonoe’ ? The colour of 'Yôraku' can vary from pale pink (Ohta-Yôraku) to white ('Kohfu-Yôraku'). I do not think that these colour differences depend on where the plant was collected. 'Yôraku' plants, found widely distributed throughout Japan, are derived from cuttings of the plant collected on the island of Oshima east of the Izu Peninsula. They are, therefore, identical, and yet their colour can vary. Perhaps the nature of the soil and its acidity level could be involved in this. I will try to change the acidity between two pots to see if this is true. H. involucrata 'Mihara Kokonoe' (photo opposite) also originates from the island of Oshima. My plant is almost pure white (then turns light green). Incidentally, the problem of the colour and shape of the inflorescence is often caused by the date the picture was taken. Each sterile flower gives birth to a new, sterile floret on the same stem. With regard to 'Kokonoe' (mountain plant) the same development process for sterile florets is involved, and the last flowers formed also take on a green colour, even if they are few in number (see p.477 Kawashima index). For both cultivars, inflorescences will differ between early and late flowering. In his 1979 book, Yamamoto gave the following explanations concerning 'Yôraku' and 'Kokonoe': “'Kokonoe' (photo opposite) was found by Prof. Tuyama in 1952 in Hakone. It has no single fertile flowers; all the fertile flowers and sterile florets are double. ... I possess a 'Kokonoe' which was collected near Hakone during the Taish_ period (1912-1926). Totally different is 'Yôraku' found by Professor Nakai in Oshima in 1948: it has a few single fertile flowers among double fertile flowers. The sterile florets are always of the double form. Another 'Yôraku' has recently been found near Kohfu. But this distinction regarding sterile florets of single or double form does not always seem to be relevant because I have a 'Mihara Kokonoe' which sometimes has single fertile flowers”. (1) Editor's Note: except for H. paniculata ssp yezoensis from northern Japan such as 'Daruma', that flowers on the previous year's growth. Annual pruning of H. involucrata during their dormant season seems to give better flowering regardless of the type.

Here are three examples, still anonymous, of probable "mutations" and a chance seedling, which make us wonder whether H. involucrata have a richer genetic heritage than we thought, which would explain this tendency towards diversification. Hydrangea involucrata (nameless seedling) This is a seedling selected by Ghent Botanical Garden for its suckering behaviour and ground covering propensity. It is a compact plant about one metre tall, with beautiful inflorescences. As it originates from a Botanical Garden, it cannot be traded commercially. H. involucrata 'Toraku Tama' (presented by Emmanuel de La Fonchais) A magnificent variety which won a prize at Courson in autumn 2009; it is a vigorous shrub, 1.5 to 2 metres tall, flowering from late August until the first frosts, with large globular inflorescences composed of pure white double sterile florets which are tinged with green at the end of the flowering season. Large oval and downy leaves are reminiscent of H. aspera. Probably a mutation of H. involucrata 'Mihara Kokonoe' (“Tous au Jardin” Nursery) A compact H. involucrata with star-shaped inflorescences The plant in the picture is probably a mutation of H. involucrata 'Yôraku' with less tightly packed inflorescences, differing from 'Yôraku' through its more or less pinkish fertile flowers, sharply dentate foliage, and small size and compact habit. (La Thyle Nursery) H. involucrata 'Hélène' A plant with white sterile florets and pale blue fertile flowers which was detected in a batch of Hydrangea involucrata and temporarily named by us (Kervilou Nursery) H. involucrata (Ghent) H. involucrata ‘Toraku-Tama’ Star-shaped H. involucrata H. involucrata ‘Hélène’ 19 Shamrock plant days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ew books A new book about the Hydrangea genus in Italy: Ortensie e idrangea: la storia, le varietà, la coltivazione (175 pages) L'Artistica, 2013 ISBN 978-88-7320-334-6 Published in September 2013, this book by Eva Boasso Ormezzano, a Natural Science teacher from Pinerolo, is interesting for a number of reasons; first of all a superb pictorial collection of the first introductions of hydrangeas to Europe in the 19th century (Curtis Botanical Magazine, coloured Flora Japonica from the National Herbarium in Leiden, among others); then 50 old and new cultivars and some Hydrangea species, presented on double-page spreads and photographed in Italian gardens therefore particularly interesting for the Italian public who until now did not have access to this kind of monograph in their own language.

Maximowiczii LEVEILLÉ (holotype),specimen kept at the Edinburgh Botanic Garden. A plant (right-hand photos, in Maurice Foster's collection) is grown by some collectors under the name H. robusta HOOKER F. & THOMSON . However, when we look at the sterile florets, we see that the sepals are entire or slightly crenate, unlike the specimen plant of H. robusta, whose sterile florets are distinctly dentate, whether in the herbarium of the New York Botanical Garden illustrated on page 10 of this journal or in the specimen type preserved at the Smithsonian. H. longipes FRANCHET, in vivo in the Shamrock Garden As the author of this article, I would like to express my sincere thanks to the Botanical Gardens of Paris, Edinburgh and New York, all of whom, by providing free scans of their herbarium specimens via internet, have enabled this article to be written. I also especially wish to thank the Biodiversity Heritage Library, which puts all the old botanical records on line free of charge, allowing researchers all over the world to carry out studies that would otherwise be almost impossible to achieve. Corinne Mallet. On the other hand this plant in vivo seems to correspond to the H. Maximoviczii LÉVEILLÉ (upper left photo), which was later grouped together with other plants under the name H. aspera ssp. robusta by Dr. McClintock, through both the general shape of the mature leaf, quite similar to the herbarium, and the resemblance of the sterile florets. The photo at lower left shows a living specimen of H. longipes FRANCHET growing in the Shamrock Collection. 23 Shamrock Events Plant Festivals Our annual "2000 hydrangeas for Shamrock" event will take place on 26 and 27 April 2014 in Varengeville.
