The University of Connecticut has developed this site dedicated to the ornamental attributes, appropriate use and identification of landscape plants. This site is geared toward the teaching of landscape plants and contains valuable information for students, homeowners and plant professionals. At the core of this site are plant information pages that contain text, photographs, illustrations and latin name pronounciations. The plants listed in this resource are meant to create an awareness of the great variety of ornamental plants that will grow in USDA hardiness zone 6 or colder, and to encourage people to think about planting a greater variety of ornamentals. The interactive Plant Selector is available to allow users to search the University of Connecticut Plant Database to find trees, shrubs and vines which meet specific landscape situations and express particular ornamental traits. ...

Die Webpräsenz "Arboles ornamentales" bietet in spanischer Sprache Beschreibungen und Fotos zu Ziergehölzen Spaniens (sowohl Bäume als auch Sträucher). Derzeit sind etwa 700 bis 800 Baumarten enthalten; weitere sollen noch hinzugefügt werden. Der Urheber ist Herausgeber der auf insgesamt 12 Bände angelegten "Flora Ornamental Espanola" und bietet auf den Webseiten, abgesehen von Holzgewächsen, auch Beschreibungen einiger anderer nichtholziger Gewächse. ...

"Seeds of Woody Plants in the United States", USDA Agric. Handbk. 450, was published in 1974. Seed data were presented for about 800 species, varieties, and sub-species in 188 genera, considerable more than the 420 species and 140 genera in the 1948 edition. The 1974 Handbook proved to be very popular both in this country and abroad, leading to five printings and translations in several other languages. More than a quarter-century after its publication, however, numerous advances in tree seed technology have dictated that a new revision is needed; the result is the current volume. ...

This atlas explores the continental-scale relations between the geographic ranges of woody plant species and climate in North America. A 25-km equal-area grid of modern climatic and bioclimatic parameters was constructed from instrumental weather records. The geographic distributions of selected tree and shrub species were digitized, and the presence or absence of each species was determined for each cell on the 25-km grid, thus providing a basis for comparing climatic data and species' distributions. The relations between climate and plant distributions are explored in graphical and tabular form. The results of this effort are primarily intended for use in biogeographic, paleoclimatic, and global-change research. These web pages provide access to the text, digital representations of figures, and supplemental data files from USGS Professional Paper 1650, chapters A and B. A printed set of these volumes can be ordered from the USGS at a cost of US$ 63.00. ... [Information of the supplier]
This interactive key to the perennial woody plants of Minnesota was developed with the goal of providing an easy-to-use guide to identification of all woody plant species occurring in the state. The key includes native species as well as naturalized introduced and commonly cultivated woody plants. [Information of the supplier]
Maps of the ranges of tree species in North America compiled by Elbert Little, of the U.S. Department of Agriculture, Forest Service, and others (see references below) were digitized for use in USGS' vegetation-climate modeling studies. These digital map files are available here for download. The maps are available in ArcView® shapefile format. Geographic ranges are represented as polygons. There is one shapefile (with associated data files) for each tree species. At present, not all of the maps have been digitized, quality checked, and made available here, but we plan to make most or all of the digitized maps available over time. ...

Virginia Tech's Tree Fact Sheets provide concise information on approximately 800 tree species of North America. Fact sheets (with morphological descriptions and photographs) are printable on one sheet of paper. [Editorial staff vifabio]
The InsideWood project integrates wood anatomical information from the literature and original observations into an internet-accessible database useful for research and teaching. The InsideWood database contains brief descriptions of woody dicots (hardwoods) from more than 200 plant families, and is searchable by an interactive, multiple-entry key. The InsideWood collection has 5,686 descriptions and 28,576 images. ... [Information of the supplier]
Dendrome is a collection of forest tree genome databases and other forest genetic information resources for the international forest genetics community. Dendrome is part of a larger collaborative effort to construct genome databases for major crop and forest species. [Information of the supplier]
The Central Database for Cultivated Woody Plants in Europe Ginkgo (www.uni-duisburg-essen.de/ginkgo) now comes into existence, after many years of preparatory work, and at the instigation of the Board of the German Dendrological Society (DDG), and in co-operation with several universities, nurseries, arboretums, botanical gardens, park administrations, nature protection and memorial garden authorities. The homepage gives an insight into the status of the registration of remarkable trees (habitat, location, growth etc.) as well as providing further knowledge about trees and shrubs (nomenclature, origin, distribution, location, growth behaviour, morphology, use, propagation, diseases etc.). More information about the database Ginkgo is found in the same place under “General”, or through the database administration. All those who themselves, out of interest, within the framework of their practical work, or in the course of their studies and diploma work, are concerned in the collection and evaluation of data on trees and shrubs (e.g. registration of specimens, protection of woods, care of memorial gardens, new planting of woods, care of woods, scope of care) may participate in the construction of the Gingko Register (after creating username and password). The woody plants inventory of DDG (1974) and simplified are made available, scientific names are partly available via and are linked to the inventory. The making available of more data such as e.g. aids to age estimation, information about habitat demands, gardening or biological engineering application possibilities, etc., is being worked on. ...
