A real turning point was the installationJardin ofacarparkcompatiblewiththe Remarqua- ble label we were awarded in 2015. Tangible support fromourmembersandfriends, the skill and hard work of the unbeatable duoofHenriGuyomard and Dominique Hébert (see page 4) helped solve this long-standingproblem. We are very grateful to the mayor and council ofVarengeville,whoputupsignsshowing the way to the collection, and also accommodatedourannualsale last April. Slightly lower visitor numbers due to the ‘state ofemergency’werecompensatedbyhigher sales of specialised books on hydrangeas, includingasmallbook by Corinne Mallet bought from Editions Ulmer and a brochure onpruningkindlygiventous by André Diéval.

All about kokedama Bernard Schumpp † 3 At the Hydrangea 2012 symposium organised by HW² in the superb infrastructure of Terra Botanica in Angers, Sophie Le Berre spoke about trends in the hydrangea market in Japan and the birth of a new segment: the “kokedama”. Kokedama (苔玉; in English, literally “moss ball” – ed.) is a sort of bonsai created with small plants in a ball of substrate surrounded by moss, able to live indoors or outdoors, depending on the choice of plants. Hydrangea serrata adapt well to being grown in kokedama, with some cultivars particularly suitable for growing as miniature plants. About Hydrangea serrata ‘Hakuryu’ The mountain hydrangea (Hydrangea serrata) is a cold-resistant plant which prefers to be grown in places with bright shade and moisture throughout the year. H. serrata ‘Hakuryu’ is a plant with very high resistance to cold and heat which is well suited to growing in kokedama. In summer, if the ball of moss becomes too light, simply soak it in water once a day; otherwise watering every two days is enough. This kokedama is very easy to grow, even for beginners. This hydrangea’s pretty flowers can be appreciated from mid-May onwards. The foliage is resplendent from spring to autumn, but ‘Hakuryu’ benefits from fine foliage throughout the year, although it can lose its leaves in winter. For city dwellers who do not have a garden, growing the plant indoors like this is a pretty and convenient method which should satisfy a large number of enthusiasts. It is even small enough to take with you on holiday. For the more enterprising, here is a link to a video showing how to make your own Kokedama: http://www.youtube.com/watch?v=pdI_WiHuEH0 From top to bottom: Hydrangea serrata as bonsai, seen by Jean-Pierre Péan and me on 15 June, 2013 at the Kyoto Botanical Garden during our trip to Japan. The craze for kokedamas was confirmed during our shopping trip in the Kyoto department stores near the central station: some kokedama H. serrata we found there. H. serrata ‘Hakuryu’ in kokedama placed in a bowl. A new car park for ‘Shamrock’ Some great teamwork 4 The highlight of 2016 was the construction of a 500-square- metre parking space, which was added to the old car park, where access was no longer possible. After brush clear- ing and wood cutting done by the indefatigable Madeleine Alves, Anne Nicolle, Daniel Kuszak and André Dieval, it was once again Henri Guyomard with his friend Dominique Hébert who worked for twelve days using public works equipment to achieve this successful result. Finishing touches were given by Jean-Marie Rouet, marking out the parking spaces, and Christophe Pannequin, this year’s bril- liant trainee, who was in charge of creating an entrance portico and finishing off some of the earthworks. Funding for this indispensable work was provided by many friends, both members and non-members of the Association, in the form of gifts or personal loans. Note that since 2016, thanks to an initiative by our treasurer Henri Pavie, the Associa- tion has obtained tax approval, allowing donors to deduct a significant percentage of their donations from their taxes.

The two large photos on the right show the finished work. Hydrangeas: Updates on new cultivars and research. Michael Dirr 1 5 Hydrangeas, particularly H. macrophylla*, have accelerated in popularity and numbers in the last de- cade, the impetus being Endless Summer®The Original®, a remontant cultivar that injected excite- ment and hope into the genus, first introduced in 2004. Along with‘Blushing Bride’, Twist-n-Shout® and BloomStruck®, over 23 million plants have been sold as of December 31, 2016 (…) Several newer releases include: BloomStruck®, a complex H. macrophylla x H. serrata hybrid with red stems, petioles and veins, superior dark green summer foliage with red-purple autumnal tints, continuous reblooming, rose to violet-blue mop head flowers, was bred by Plant Introductions, and introduced by Bailey Nursery, in the Endless Summer® brand. Enchantress®, a ruby-black stem rebloomer, a sport of Endless Summer® (verified by DNA molecular markers), is offered by Monro- via Nursery. Electric Rouge™ (‘KOLMARU’) is a reblooming mop head with reddish pink fluorescent flowers from Ball Ornamentals (now Star Roses and Plants) and introduced via the HGTV Home Plant Collection. Dear Delores™, a rebloomer, from the Southern Living Collection, lines up genetically with Endless Summer® The Original as determined by molecular markers. Fuchsia Glow™, a red mop head, from Garden Debut®, Let’s Dance Rave™ and Let’s Dance Rhythmic Blue™ are 2015 introduc- tions (Proven Winners) described as formidable rebloomers. Fuchsia Glow™

A Gap Analysis of the Morris Arboretum Hydrangea Collection: Sections Asperae and Chinensis This report is available at ScholarlyCommons: https://repository.upenn.edu/morrisarboretum_internreports/68 Title: A Gap Analysis of the Morris Arboretum Hydrangea Collection: Sections Asperae and Chinensis Author: Emily Conn The Martha J. Wallace Endowed Plant Propagation Intern Date: January 2020 Abstract: In this gap analysis of the Morris Arboretum’s Hydrangea collection, I will assess the hydrangea collection with a focus on the “fuzzy leaf” varieties that fall under two classifications: Section Asperae and Section Chinenses. Within these fuzzy leaf groupings, this project will include an analysis of the collection at the species and cultivar level and will outline which hydrangeas are missing from or underrepresented in our collection, as well as recommendations for suitable additions. These recommendations favor wild collected species and species available from the collections at regional arboreta. Discussion of the controversy over nomenclature verification methods, phylogenic treatments, and theories of biological classification systems are explored in the body of this paper. This project also entails seed propagation of target species growing at the Arboretum, and cutting propagation of desired species from local institutions to diversify this growing collection.

  • Hydrangeas More Than You Ever Wanted to Know (MTYEWTK)
    Hydrangeas More Than You Ever Wanted to Know (MTYEWTK) When I first got interested in hydrangeas, I have to admit I considered the ones I had seen to be kind of “grandma plants” not worth a place in my garden. Then one day at the Washington Park Arboretum I ran into a magnificent hydrangea aspera in peak flower and a new “kick” was born. Maybe it was the hydrangea and maybe it was the fact that I am now a grandpa, but I fell in love. Since then, Bethany and I have scoured wholesale nurseries and botanical gardens to find beautiful hydrangeas for Lael’s Moon Garden and some of our favorites are described below. Hydrangea aspera ‘Macrophylla’ has stunning lace cap flowers of soft purple with stark white sterile florets surrounding them. The plant has large, dark green fuzzy leaves and the flowers extend above the leaves giving it a distinctive look. (A friend called it the Hydrangea from Mars.) This is a large shrub growing to eight feet tall and wide. Afternoon shade is a must; it will sunburn in hot sun. Prune hard when young to develop good branching; thereafter prune lightly to remove dead, crossing or poorly formed branches in late winter or early spring. Hydrangea macrophylla ‘Oregon Pride’ is a stunner. It has dark burgundy stems and strong pink mop head flowers. But there’s more! In our slightly acid soil it has a variety of flower colors all on one plant. Some flowers are the expected strong pink, some are a vibrant purple and some are shades in between.

  • A Plantsman's Observations on the Genus Hydrangea
    Davidsonia 14:2 31 A Plantsman’s Observations on the Genus Hydrangea The hydrangea family, Hydrangeaceae, is a respectable conglomeration of shrubs, vines and herbaceous perennials resulting from a recent extraction from a behemoth institution known as the Saxifragaceae. The herbaceous components, in the respective genera of Cardiandra and Deinanthe proffer ornamental species for cultivation although it is the woody taxa of shrubs and lianas of this family, in the genera Hydrangea, Deutzia, Philadelphus, Platycrater and Schizophragma, that are by far the most familiar. Other than the exceptions of Hydrangea paniculata and H. quercifolia, the prototypical hydrangea inflorescence is a corymb; a rounded disc of numerous small, fertile flowers that possess insignificant sepals and four or five small often white, pink or blue petals. This cluster of ‘utility’ is surrounded by the advertising agency of sterile florets, or ray flowers, that provide the stuff of ornament. The ovaries are, as a rule, inferior (i.e., enclosed in the receptacle), while the dehiscent capsules, sometimes in the shape of a Grecian water jar, gave rise to the genus name; hydro, water and angeion, a vessel. The foliage is, without exception, arranged in pairs. This floral strategy of sacrificing the fertility of a few flowers to provoke a bit of curiosity by commuting pollinators has co-evolved in other non- related groups, most notably in the genus Viburnum. Thus, it would not come as a complete surprise to those who have grown a double-file viburnum, Viburnum plicatum, that the second Asiatic hydrangea to be noted by Western botanists (in Japan, in 1777) was named Viburnum serratum.
