The information below will guide you in purchasing a properly sized wire basket or container for your shade trees. Type 1 shade trees Climatic conditions in different regions of the country produce trees of different caliper-heights. The table below shows average height ranges and the typical maximum heights. Examples of type 1 shade trees: Acacia stenophylla, Acer rubrum, A. saccharinum, Betula, Cinnamomum camphora, Eucalyptus microtheca, Fraxinus, Ginkgo, Gleditsia, Liriodendron, Platanus, Populus, Quercus macrocarpa, Q. palustris, Q. phellos, Q. virginiana (southeastern climates), Salix. Tilia Americana, and Zelkova serrata.

Type 2 shade trees Trees of slower growth than type 1 that will not usually attain the height measurement in relation to caliper as in type 1. The height, however, should not be less than two-thirds the height relationship given for type 1. The table below shows average height ranges and the typical maximum heights. Examples of type 2 shade trees: Aesculus pavia, Brachychiton acerifolius, Celtis reticulata, Cladrastis lutea (kentukea), Cocculus laurifolius, Conocarpus erectus var. sericeus, Fagus sylvatica, Koelreuteria paniculata, Liquidamber styraciflua, Magnolia grandiflora, Nyssa sylvatica, Quercus alba, Q. fusiformis, Sorbus sucuparia, Syringa reticulata, Tabebuia cariaba, Tilia cordata, and T. euchlora.
