"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -
HYDRANGEA CARE Hydrangeas Can Be Confusing When It Comes to Requirements and Especially Pruning
HYDRANGEA CARE Hydrangeas can be confusing when it comes to requirements and especially pruning. We’ve broken down the hydrangeas we carry into three basic groups to easily explain the differences. HYDRANGEA ARBORESCENS (SMOOTH HYDRANGEA) Smooth hydrangeas are some of the easiest to grow and lowest maintenance hydrangeas. They are known for their large flower heads, sturdy stems, and great cut flowers. They almost always bloom on new wood which means they should be pruned in late fall. Smooth hydrangeas can be cut back 6-8” from the ground in late fall if desired. Includes: Annabelle & Invincible Spirit II (and others) HYDRANGEA MACROPHYLLA (BIGLEAF HYDRANGEA) Bigleaf or “ever-blooming” hydrangeas are desired for their deep green leaves, numerous blooms, and easy care. Bigleaf hydrangeas bloom on both new and old wood, but most of their summer blooms occur on wood formed the previous summer. To encourage new blooms throughout the summer, remove spent blooms as soon as they’re done flowering. The sooner this is done, the longer the plant will be allowed to recover and set new buds for the next season. This will encourage larger and more numerous blooms. Bigleaf hydrangeas prefer a location where they receive morning sun (about 4 hours) but are shaded from the afternoon sun. If they are planted in an area with total shade, it is not likely that they will bloom. Includes: Endless Summer, Blushing Bride, Seaside Cape Cod, Grateful Red, & Bloomstruck (and others) HYDRANGEA PANICULATA (GRANDIFLORA HYDRANGEA) Grandiflora hydrangeas are some of the most commonly planted hydrangeas in this area. They are tolerant of numerous conditions and are easy to grow. -

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. -
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.

Wa Shan – Emei Shan, a Further Comparison

At its far left the mist-filled Dadu River gorge drops to 500-600m. To its right the 3048m high peak of Mao Kou Shan climbed by Ernest Wilson on 3 July 1903. “As seen from the top of Mount Omei, it resembles a huge Noah’s Ark, broadside on, perched high up amongst the clouds” (Wilson 1913, describing Wa Shan floating in the proverbial ‘sea of clouds’). Wa Shan – Emei Shan, a further comparison CHRIS CALLAGHAN of the Australian Bicentennial Arboretum 72 updates his woody plants comparison of Wa Shan and its sister mountain, World Heritage-listed Emei Shan, finding Wa Shan to be deserving of recognition as one of the planet’s top hotspots for biological diversity. The founding fathers of modern day botany in China all trained at western institutions in Europe and America during the early decades of last century. In particular, a number of these eminent Chinese botanists, Qian Songshu (Prof. S. S. Chien), Hu Xiansu (Dr H. H. Hu of Metasequoia fame), Chen Huanyong (Prof. W. Y. Chun, lead author of Cathaya argyrophylla), Zhong Xinxuan (Prof. H. H. Chung) and Prof. Yung Chen, undertook their training at various institutions at Harvard University between 1916 and 1926 before returning home to estab- lish the initial Chinese botanical research institutions, initiate botanical exploration and create the earliest botanical gardens of China (Li 1944). It is not too much to expect that at least some of them would have had personal encounters with Ernest ‘Chinese’ Wilson who was stationed at the Arnold Arboretum of Harvard between 1910 and 1930 for the final 20 years of his life. -

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.

(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. -
Landscaping Near Black Walnut Trees
Selecting juglone-tolerant plants Landscaping Near Black Walnut Trees Black walnut trees (Juglans nigra) can be very attractive in the home landscape when grown as shade trees, reaching a potential height of 100 feet. The walnuts they produce are a food source for squirrels, other wildlife and people as well. However, whether a black walnut tree already exists on your property or you are considering planting one, be aware that black walnuts produce juglone. This is a natural but toxic chemical they produce to reduce competition for resources from other plants. This natural self-defense mechanism can be harmful to nearby plants causing “walnut wilt.” Having a walnut tree in your landscape, however, certainly does not mean the landscape will be barren. Not all plants are sensitive to juglone. Many trees, vines, shrubs, ground covers, annuals and perennials will grow and even thrive in close proximity to a walnut tree. Production and Effect of Juglone Toxicity Juglone, which occurs in all parts of the black walnut tree, can affect other plants by several means: Stems Through root contact Leaves Through leakage or decay in the soil Through falling and decaying leaves When rain leaches and drips juglone from leaves Nuts and hulls and branches onto plants below. Juglone is most concentrated in the buds, nut hulls and All parts of the black walnut tree produce roots and, to a lesser degree, in leaves and stems. Plants toxic juglone to varying degrees. located beneath the canopy of walnut trees are most at risk. In general, the toxic zone around a mature walnut tree is within 50 to 60 feet of the trunk, but can extend to 80 feet. -
