Tubestock Trader September 2018 Dichroa febrifuga 'Blue Cap' Aquilegia 'Songbird Blue' Clive’s Comments I started writing this article in mid-August whilst I was in Shanghai. I was there as Vice President of IPPS International and working with local Chinese to set up IPPS China. I was also working with director of Shanghai Real Estate and Garden Company on their plans for the major China Plant and Flower Expo in 2021. As I have mentioned in prior articles the whole way China approaches owering plants is inspiring. When we were there Gaillardia x grandiora 'Mesa Yellow' in May for initial IPPS China conference we were astounded by the rose plantings along the freeways of Hangzhou. We think there was 100km plus of freeway all lined with perfect roses in full ower. Stunning! Wish we could do the same here. I was only in Shanghai for three days of meetings but two of those were cancelled due to typhoons. So whilst sitting in hotel lobby working on laptop I started writing. The way the Chinese responded to the call by the president to ‘Color China with Plants’ was amazing. It made us (Australian nurserymen) jealous due to the increased demand for plants. However as a free thinking Australian, I (and others in the group) felt somewhat uncomfortable at the eorts local Chinese went to ‘obey’ the president. The nurseries benetted from the call but it shows the level of governmental control over the community...

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. -

Toxicological Evaluation of the Ultrasonic Extract from Dichroae Radix in Mice and Wistar Rats
www.nature.com/scientificreports OPEN Toxicological evaluation of the ultrasonic extract from Dichroae radix in mice and wistar rats Ling Wang *, Zhiting Guo *, Dongan Cui, Shahbaz Ul Haq, Wenzhu Guo, Feng Yang & Hang Zhang This study was aimed at evaluating the acute and subchronic toxicity of ultrasonic extract of Dichroae radix (UEDR) in mice and rats. High performance liquid chromatography (HPLC) and thin layer chromatogrephy (TLC) were used to detect β-dichroine and α-dichroine in UEDR for quality control. The levels of β-dichroine and α-dichroine in UEDR were 1.46 and 1.53 mg/g, respectively. An oral LD50 of 2.43 g/kg BW was observed in acute toxicity test. After 28-day repeated oral administration, compared with the control group, treatment-related changes in body weight (BW) and body weight gain (BWG), lymphocyte counts and ratios, as well as in the relative organ weights (ROWs) of liver, kidney, lung, and heart, were detected in the middle- and high-dose groups (P < 0.05, P < 0.01), no diferences were noted in the serum biochemical parameters and necropsy examinations in both sexes at all doses. Histopathological examinations exhibited UEDR-associated signs of toxicity or abnormalities. After 14 days withdrawal, no statistically signifcant or toxicologically relevant diferences were observed in any of the UEDR-treated groups, and the hispathological lesions in the high-dose group were alleviated. Findings showed that long-course and high-dose of UEDR administration was toxic, and showed dose-dependence, the toxic damage was reversible. -

French Hydrangea for Gardens in North and Central Florida1 Gary W
ENH1069 French Hydrangea for Gardens in North and Central Florida1 Gary W. Knox2 French hydrangea (Hydrangea macrophylla) is a shade- preferring shrub producing ball-shaped or flat clusters of white, pink, blue or purple flowers, depending on soil conditions and cultivar. “Mophead” or “hortensia” hydran- geas (Figure 1) have ball-shaped flower clusters, whereas “lacecap” hydrangeas have flat clusters of tiny, spidery flowers surrounded by a ring of prominent flowers (Figure 2). French hydrangea, also known as bigleaf hydrangea, is the most widely grown species of Hydrangea. Figure 2. The lacecap flower of ‘Mowe’ in its pink form. Origin and Development of French Hydrangea Two forms of Hydrangea macrophylla are native to eastern Asia. Bigleaf hydrangea, Hydrangea macrophylla var. macrophylla, is native to China and coastal areas of Japan. Mountain hydrangea, H. macrophylla var. serrata, is native to China and upland areas of Japan and Korea. Mountain Figure 1. The mophead flower of ‘Decatur Blue’ in its blue form. hydrangea is generally smaller in size and flowers earlier. Some experts consider it more cold-hardy than bigleaf hydrangea. The two natural varieties are otherwise very similar, and both types may produce mophead or lacecap flowers, depending on the selection. 1.

Hydrangeas, Garden Tours, Plant Sale and Autumn in the Country
Page 1 of 6 Lael's Moon Garden Nursery From: "Lael's Moon Garden Nursery" <[email protected]> To: "Bethany Lael" <[email protected]> Sent: Tuesday, September 01, 2009 7:10 PM Subject: Hydrangeas, Garden Tours, Plant Sale and Autumn in the Country Lael's Moon Garden Greetings Fellow Gardeners: Finally some cooler weather so we can play in our gardens again! I am in awe of people like Dan Hinkley who have the time, energy and knowledge (not to mention money) to travel to the four corners of the world observing rare plants in their native habitats and introducing them to horticulture. My admiration is not diminished by the fact that he writes a little like Frazier Crane talks. My own study of horticulture has consisted of going on "kicks" where I try to learn as much as I can about a particular genus that piques my interest until I get jaded with it and move on to another. Over time, this has given me knowledge of lots of groups of plants with vast chasms of ignorance in between. 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. -
Trees, Shrubs, and Perennials That Intrigue Me (Gymnosperms First
Big-picture, evolutionary view of trees and shrubs (and a few of my favorite herbaceous perennials), ver. 2007-11-04 Descriptions of the trees and shrubs taken (stolen!!!) from online sources, from my own observations in and around Greenwood Lake, NY, and from these books: • Dirr’s Hardy Trees and Shrubs, Michael A. Dirr, Timber Press, © 1997 • Trees of North America (Golden field guide), C. Frank Brockman, St. Martin’s Press, © 2001 • Smithsonian Handbooks, Trees, Allen J. Coombes, Dorling Kindersley, © 2002 • Native Trees for North American Landscapes, Guy Sternberg with Jim Wilson, Timber Press, © 2004 • Complete Trees, Shrubs, and Hedges, Jacqueline Hériteau, © 2006 They are generally listed from most ancient to most recently evolved. (I’m not sure if this is true for the rosids and asterids, starting on page 30. I just listed them in the same order as Angiosperm Phylogeny Group II.) This document started out as my personal landscaping plan and morphed into something almost unwieldy and phantasmagorical. Key to symbols and colored text: Checkboxes indicate species and/or cultivars that I want. Checkmarks indicate those that I have (or that one of my neighbors has). Text in blue indicates shrub or hedge. (Unfinished task – there is no text in blue other than this text right here.) Text in red indicates that the species or cultivar is undesirable: • Out of range climatically (either wrong zone, or won’t do well because of differences in moisture or seasons, even though it is in the “right” zone). • Will grow too tall or wide and simply won’t fit well on my property. -
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. -
