Research Reports Response of Five Hydrangea Species to Foliar Salt Spray1
Research Reports Response of Five Hydrangea Species to Foliar Salt Spray1 N. Barbara Conolly2, Nina L. Bassuk3, and Patrick F. MacRae Jr.4 Urban Horticulture Institute, Department of Horticulture Cornell University, Ithaca, NY 14853 Abstract Hydrangeas are popular seaside plants; however, other than in anecdotal reports, there are no studies measuring their relative tolerance to salt spray. We examined response of ten cultivars and one subspecies of Hydrangea representing fi ve species to foliar-applied salt solutions to recommend selections for seaside landscapes. Objectives were to determine whether there are differences in responses to salt spray among cultivars and species, and to determine whether varying concentrations of sodium chloride differentially damaged the plants. Plants were treated with a full-strength (ion concentration approximate to seawater) salt solution, a half-strength salt solution, or a control of tap water. Plants were rated after seven once-weekly applications based on percentage necrotic leaf area, an aesthetically and physiologically important symptom of damage. Cultivars of Hydrangea macrophylla and Hydrangea serrata were more tolerant of full-strength salt spray than cultivars of H. paniculata, H. anomala and H. arborescens. At half strength but not full strength, H. anomala ssp. petiolaris was most tolerant. Hydrangea macrophylla and H. serrata were the second most tolerant of half-strength applications. Hydrangea macrophylla or Hydrangea serrata should be planted where maritime salt spray will occur. Index words: seawater aerosol, NaCl, Hydrangeaceae. Species used in this study: Smooth hydrangea (Hydrangea arborescens L.) cultivars ‘Annabelle’, ‘Dardom’ White Dome®, ‘Hayes Starburst’; bigleaf hydrangea (Hydrangea macrophylla (Thunb.) Ser.) cultivars ‘Paris’ (Cityline™ series), ‘Nikko Blue’, ‘All Summer Beauty’; panicle hydrangea (Hydrangea paniculata Sieb.) cultivars ‘Limelight’, ‘Tardiva’; Hydrangea serrata (Thunb.) Ser. -

At the Botanic Gardens, 2016 BENEFIT PLANT SALE CATALOG our primary focus is always students and learning, and 2015 was a great year. Students are integral to almost everything we do, from project installation to plant collections care, to grounds mainte- nance, plant records management, and plant propagation, to name but a few responsibilities. They are undergraduates, graduate stu- dents, master gardeners, and volunteers, and their work is seen and appreciated by industry professionals and visitors. While the sale is a key fundraiser, I hope it is also educational for our customers. This catalog is as much an educational reference as it is a sales inventory; new plants are featured along with old favorites, and the ornamental qualities of less familiar plants are highlighted through our specially selected, featured plants. I greatly appreciate the long-term support of our Friends members. In recognition and appreciation of this support, we will again offer members 10% off their entire purchase under $100, 15% off their purchase of $100 but less than $200, and 20% off their purchase of $200 or more, all plants, all day on Members Day, Thursday only. -

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. -
Threatened Lilies Reach for the Sky
Threatened Lilies Reach for the Sky I was thinking the other day about an old friend, conservationist Rusty Walton, who passed away last year. To say he was quiet would be an understatement. I could rarely make a smile bend on his face no matter how hard I tried. However, as I think back on the times I spent with him it always makes me smile. He was a dedicated naturalist and an accomplished ecologist. He introduced me to my first wild patch of wood lily on the Vineyard almost ten years ago. Recently I went back to the same spot, and surprisingly the lilies, like Rusty were gone. The wood lily (Lilium philadelphicum) has been drastically reduced on the Vineyard by large populations of deer. Wood lily has a natural distribution range across thirty seven US states. However similar to here on the Vineyard, they are losing ground across North American due to the over population of deer. Frequently I am asked about what it means when a plant goes extinct. On the Vineyard I am talking about “local” extinction, not the complete loss of a species from our planet. The underlying tragedy of local species extinction is the loss of the co-dependent species that have formed a mutualistic (beneficial) relationship with plants. These species include its insect pollinators that use it as a nectar source, and insects that may also feed on parts of the plant or lay their eggs on it to support their lifecycle. The dependence goes further with the birds that feed on those insects. -

The restoration plan was prepared by combining the diagnostic assessment for the damaged forest ecosystem and the reference information obtained from the conservation reserve with an intact forest ecosystem. The restoration plan includes the method for the amelioration of the acidified soil and the plant species to be introduced for restoration of the damaged vegetation depending on the degree of damage. Background and Objectives: The forest ecosystem around the Seokpo smelter was so severely damaged that denuded lands without any vegetation appear, and landslides continue. Therefore, Citation: Kim, R.A.; Lim, B.S.; Seol, restoration actions are urgently required to prevent more land degradation. -

De boerenhortensia (Hydrangea macrophylla) is bijna een deel van onze cultuurhistorie geworden en vrijwel iedereen kent ‘Annabelle’. Voor gebruik in de openbare ruimte zouden ze minder geschikt zijn omdat ze te veel water, voeding en onderhoud zouden vragen. Volgens de experts berust dit echter op een misverstand.

In May, August, and September 2019 and in May and July 2020, all of vascular plants were recorded, and endangered, Korea endemic, and exotic plant species were further identified. The study site contained a total of 418 floral taxa (98 families, 261 genera, 384 species, 4 subspecies, 27 variations, and 3 formations), in which Magnoliophyta accounted for larger proportion (95.2%) than Pteridophyta (3.6%) and Pinophyta (1.2%). In addition, 1 endangered (Cypripedium macranthos Sw.) and 5 Korea endemic species (Aconitum pseudolaeve Nakai, Eleutherococcus divaricatus var. chiisanensis [Nakai] C.H. Kim & B.-Y. Sun, Lonicera subsessilis Rehder, Paulownia coreana Uyeki, and Weigela subsessilis [Nakai] L.H. Bailey) were detected. The number of exotic species was 33, consisting of 4 invasive-exotic, 4 potentially invasive-exotic, and 25 non-invasive species. Compared to a previous assessment before the establishment of the center (in 2014), there were increases in total floral taxa (from 361 to 418), endangered species (from 0 to 1), and exotic species (from 26 to 33). -
