Shrub Buxus 'Green Gem' [Green Gem Boxwood] This species is a hybrid of Buxus sinica and Buxus sempervirens and is described as a perfect round ball. Hardier than var. insularis 'Winter Beauty'. Requires little prunning and shearing. Avoid cultivating around plants because they have a shallow root. Roots appreciate a good mulch ( 1-2"). Thin plants and remove damaged branches annually to improve air circulation. Buxus X 'Green Gem' is best suited to a sheltered lacation which protects it in the winter…
Tree Indiana Native Carpinus caroliniana [American Hornbeam] A clean, trouble-free small tree, useful in intensive situations such as patios and malls, and equally interesting in naturalized plantings. Useful as a large hedge if coppiced when young. Performs well in heavy shade and tolerates periodic flooding. Difficult to transplant. Move balled-and-burlapped for best results. Sometimes called Blue Beech and Ironwood (although these are best not used).
Shrub Indiana Native Ilex glabra [Inkberry] This species, like other hollies, is dioecious, so plant females for fruit and an occasional male for pollination. Withstands severe pruning. Winter desiccation injury to leaves occurs in exposed sites, with severe yellowing when temperatures drop below -20 degrees F. Avoid high pH soils.
Tree Indiana Native Ilex opaca [American Holly] This species, like other hollies, is dioecious, so plant females for fruit and an occasional male for pollination. Winter dessication injury can occur on leaves in exposed sites. Holly leaf miners are one of the major problem pests for Ilex opaca.
Tree Indiana Native Quercus montana [Chestnut Oak] Naturally grows in rocky places and poor, dry sites. Dislikes poor drainage. Bark has the highest tannin content of any Quercus species.
Tree Ulmus × 'Frontier' [Frontier Elm] Small tree that grows well under city conditions. Good Dutch elm disease resistance and moderate elm leaf beetle resistance.
