Aesculus Flava Aesculus flava - Yellow Buckeye (Hippocastanaceae) ---------------------------------------------------------------------------------------- Aesculus flava is a large, deciduous, native Ohio tree Fruits known for its tall stately growth habit, prominent -light brown, smooth, obovate capsules split open in yellow inflorescences in spring, clean summer Sept.-Oct. to generally yield 2 - 2" wide brown nuts foliage, and fruits in autumn.

  • Suggested Trees for the Great Plains
    THE NEBRASKA STATEWIDE ARBORETUM PRESENTS A FEW TREES TO REPLACE ASH The following list is recommended for homeowners seeking replacement options for ash trees. Beware that no tree is a perfect replacement and some species have specific site limitations. For a more thorough and informative list, please visit plantnebraska.org or nfs.unl.edu/ash-replacements. 1. Bur Oak - and related species (Quercus macrocarpa): Bur oak is an outstanding, majestic native tree with amazing drought tolerance; great for wildlife; 50-70’ x 50-75’. Related oaks include Chinkapin Oak (Q. muehlenbergii), Swamp White Oak (Q. bicolor - limit to eastern Nebraska), and Gambel Oak (Q. gambelii) a species well-suited to western Nebraska. 2. Red Oak - and related species (Quercus rubra): Red oaks are less tolerant of high pH soils and are generally more suited to eastern Nebraska; closely related species include Red Oak, Shumard Oak, Black Oak, Buckley Oak, and Shingle Oak; most species tough and reliable with lustrous sharp-pointed leaves and beautiful fall color from russet to bright red in fall; 40-60’x 40-60’. 3. American Linden - and related species (Tilia americana): American linden is a tough and adaptable native with fragrant spring flowers favored by bees and other pollinators; 60’x 40’. Littleleaf linden (Tilia cordata) is similar but with a more formal, pyramidal shape. Silver linden (Tilia tomentosa) has very attractive dark-green leaves with pubescent (silvery) undersides that give them better resistance to Japanese beetles. 4. Coffeetree (Gymnocladus dioicus): Native; amazingly adaptable; coarse outline with beautiful winter form; female trees have fairly large oblong seed pods containing the very hard “coffeetree” seeds; 50-60’x 40-50’.

Horse Bucks) Maples Ashes Dogwoods Horse Chestnuts Buckeyes - alternate (Others) - whorled (Catalpa sp.) • Shape and color of buds • Shape and color of leaf scars • Color and structure of tree bark General Notes • Species with opposite arrangements are near the front of the reference, while species with alternate and whorled arrangements are near the back. • Each species has the common name, genus and species, as well as the family name listed. Genus and species names are in italics and the family names all end in “AE.” • A species marked with a denotes a species that we would like to have a location reported, so we can collect seed when the time is right. Lastly, this is by no means a complete guide to native trees in Illinois. It is simply a compilation of common trees that could be encountered during a hike in the woods. More trees will be added to this reference in the future so that a more complete guide can be generated Thank You and Enjoy! Maple Aceraceae Acer sp. Box Elder Acer negundo Distinguishing features • Buds are opposite. • Twig color is red. • White hairs are present on buds, creating a white “frost” on twig. Maple Aceraceae Acer sp.

    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.

Vascular Flora (Appendix 3) Methods and Materials To compile a thorough vascular flora survey, several examples of different plant communities at numerous sites were visited and sampled during the study. Approximately 45 minutes was spent documenting community structure at each site. Lastly, all habitats, ecological systems, and plant associations found within the property boundaries were defined based on floristic content, soil characteristics (soil maps) and other abiotic factors.
