Native Herbaceous Perennials and Ferns for Shade Gardens
Green Spring Gardens 4603 Green Spring Rd ● Alexandria ● VA 22312 Phone: 703-642-5173 ● TTY: 703-803-3354 www.fairfaxcounty.gov/parks/greenspring NATIVE HERBACEOUS PERENNIALS AND FERNS FOR � SHADE GARDENS IN THE WASHINGTON, D.C. AREA � Native plants are species that existed in Virginia before Jamestown, Virginia was founded in 1607. They are uniquely adapted to local conditions. Native plants provide food and shelter for a myriad of birds, butterflies, and other wildlife. Best of all, gardeners can feel the satisfaction of preserving a part of our natural heritage while enjoying the beauty of native plants in the garden. Hardy herbaceous perennials form little or no woody tissue and live for several years. Some of these plants are short-lived and may live only three years, such as wild columbine, while others can live for decades. They are a group of plants that gardeners are very passionate about because of their lovely foliage and flowers, as well as their wide variety of textures, forms, and heights. Most of these plants are deciduous and die back to the ground in the winter. Ferns, in contrast, have no flowers but grace our gardens with their beautiful foliage. Herbaceous perennials and ferns are a joy to garden with because they are easily moved to create new design combinations and provide an ever-changing scene in the garden. They are appropriate for a wide range of shade gardens, from more formal gardens to naturalistic woodland gardens. The following are useful definitions: Cultivar (cv.) – a cultivated variety designated by single quotes, such as ‘Autumn Bride’. -
"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. -

Topping Trees Is Not Proper Pruning - Chuck Schmitt Think before you top your tree... Homeowners often feel that their trees have become too large and now pose a hazard to their house or other structures, so they have their trees topped, believing this will not only reduce the tree's size but that it will also decrease potential hazards. What they do not realize is that though they now have a smaller tree, it is probably a greater hazard than before it was cut. -

This comprises the largest and highest area of montane habitat in Britain, much of which is in a relatively pristine condition. It contains the main summits and plateaux with their associated corries, rocky cliffs, crags, boulder fields, scree slopes and the higher parts of some glens and passes. The vegeta- tion is influenced by factors such as exposure, snow cover and soil type. The main zone is considered to be one of the most spectacular mountain areas in Britain and is recognised nationally and internationally for the quality of its geology, geomorphology and topographic features, and associated soils and biodiversity. c14.5% of the Cairngorms Partnership area (75,000ha) is land above 600m asl. Upland heathland is the most extensive habitat type in the Cairngorms Partnership area, covering c41% of the area, frequently in mosaics with blanket bog. -

TALL BEECH FERN a New Beech
TALL BEECH FERN A new beech fern in New England, New York, and Canada Arthur V. Gilman 16 January 2020 This document is meant to be an aid to identification of Phegopteris excelsior, tall beech fern, which has recently been recognized as a new, but cryptic, species. As outlined below, evidence shows it is of hybrid origin, with half or even three quarters of its genome contributed by long beech fern and the rest by another beech fern species—but what (and where) that species may be, is yet unknown. Its resemblance to the long beech fern in its heritage means tall beech fern can be difficult to identify. My experience over the past 25 years, however, is that it can be field-identified—at least, if plants are relatively well-grown and robust. I have found it in approximately 15–20 locations, more or less evenly divided between central Maine and northern Vermont, where most of my field work has been done. This guide is primarily visual, showing well-grown plants and giving some pointers on the diagnostic characters. Unfortunately, no completely unequivocal visual characters have emerged and only chromosome number and molecular markers are one hundred percent diagnostic. Nevertheless, avid pteridologists should be able to confidently identify a large majority of plants encountered, based on the images presented here. I wish to thank Niki Patel and Susan Fawcett, my co-authors on the paper that formalized P. excelsior, with special thanks also extended to David Barrington and Heather Driscoll. These botanists accomplished laboratory work and data analysis far beyond my capabilities, which are mainly those of a field botanist. -
Review of Selected Literature and Epiphyte Classification
--------- -- ---------· 4 CHAPTER 1 REVIEW OF SELECTED LITERATURE AND EPIPHYTE CLASSIFICATION 1.1 Review of Selected, Relevant Literature (p. 5) Several important aspects of epiphyte biology and ecology that are not investigated as part of this work, are reviewed, particularly those published on more. recently. 1.2 Epiphyte Classification and Terminology (p.11) is reviewed and the system used here is outlined and defined. A glossary of terms, as used here, is given. 5 1.1 Review of Selected, Relevant Li.terature Since the main works of Schimper were published (1884, 1888, 1898), particularly Die Epiphytische Vegetation Amerikas (1888), many workers have written on many aspects of epiphyte biology and ecology. Most of these will not be reviewed here because they are not directly relevant to the present study or have been effectively reviewed by others. A few papers that are keys to the earlier literature will be mentioned but most of the review will deal with topics that have not been reviewed separately within the chapters of this project where relevant (i.e. epiphyte classification and terminology, aspects of epiphyte synecology and CAM in the epiphyt~s). Reviewed here are some special problems of epiphytes, particularly water and mineral availability, uptake and cycling, general nutritional strategies and matters related to these. Also, all Australian works of any substance on vascular epiphytes are briefly discussed. some key earlier papers include that of Pessin (1925), an autecology of an epiphytic fern, which investigated a number of factors specifically related to epiphytism; he also reviewed more than 20 papers written from the early 1880 1 s onwards. -
