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. -
Deutzia John Frett and Andrew Adams
Deutzia John Frett and Andrew Adams Deutzia is a large genus with more than 60 species and even more cultivars. It is a group of plants that is grown widely in the US, Europe and Asia primarily for its flowers. It has been popular in the US since its use in Victorian gardens, but the deutzia of today is nothing like that Deutzia ‘Mont Rose’ Deutzia ×kalmiiflora of days gone by. Old-fashioned Deutzia Photo: Andrew Adams Photo: Andrew Adams were more commonly large, 6–12 feet tall, upright shrubs frequently with vase Most of today’s popular Deutzia are smaller and more shape or arching habit. These plants were stunning with compact. Several of the selections offered in the sale grow typically white flowers in the spring garden, then fading 1–2 feet tall and wide, functioning more as a groundcover into the background during the summer and fall. Fruits are a than an individual shrub. These plants are best planted in dry capsule of little ornamental or wildlife value and foliage groups and are especially suitable for slopes. They are even becoming a dirty yellow before dropping in the autumn. They small enough to be integrated into the perennial border but were useful plants in larger gardens and shrub borders where do not cut them back in the fall as these shrubs flower in they could be combined with other shrubs to provide year- the spring. This means they flower on last year’s stems. If you round interest. want to tidy up these compact plants, cut them to the ground The traditional Deutzia are still after flowering and they will regrow and produce flowers very useful in today’s shrub the following spring. -
Fuzzy Pride-Of-Rochester Deutzia Scabra Thunb
Weed of the Week Fuzzy Pride-of-Rochester Deutzia scabra Thunb. Common Names: deutzia, fuzzy deutzia, pride-of- Rochester, fuzzy pride-of-Rochester Native Origin: Eastern Asia - China, Japan, Korea; introduced in 1880. Description: A large deciduous shrub in the hydrangea family (Hydrangeaceae) growing to a height 6 to 10 feet and width of 4 to 8 feet with an open, arching crown. The bark is reddish brown to orange-brown and exfoliates in large sheets. Slender stems are fuzzy/scabrous, red-brown to green, with hollow piths and pointed buds. Leaves are opposite, simple, serrate, and slightly pubescent on both surfaces, giving them a rough, fuzzy/scabrous feel. Light green leaves are 4 inches long and 2 inches wide with a rounded leaf base. Flowers are white tinged with a rosy- purple color on the outside of the corolla, fragrant, and borne on a panicle to 6 inches. Flowers are produced on the previous season’s wood and appear in late spring to early summer (April – July). The fruit is a 1/4 inch dry brown capsule that ripens in early fall and persists through the winter. It reproduces through seeds. Habitat: It grows in full sun, semi-shade, or moderately heavy shade. It tolerates most soils but prefers moist well- drained fertile soils. This ornamental plant can be found in landscaped gardens, open woodlands and shady forest edges. In Kentucky state parks fuzzy pride-of- Rochester invades woodlands areas of sugar maple, buckeye, and magnolia trees. Distribution: This species is reported from states shaded on Plants Database map. -

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. -
