Shrub Ilex glabra 'Green Magic' [Green Magic Inkberry] 'Green Magin' is a dense, compact hardy cutlivar that tends to hold on to its lower branches better than many other variants of Ilex glabra. 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 desiccation injury can occur on leaves in exposed sites. Holly leaf miners are one of the major pest problems for Ilex opaca.
Shrub Ilex verticillata 'Berry Heavy' [Berry Heavy Common Winterberry] Bright red fruits abundantly set; 6 to 8' high; 'Jim Dandy' is recommended as the male pollinator; Spring Meadow introduction.
Shrub Ilex verticillata 'Jim Dandy' [Jim Dandy Common Winterberry] This species, like other hollies, is dioecious, and 'Jim Dandy' is an early-flowering male cultivar suited for pollinating northern female variants, such as 'Red Sprite'. The slow growing Jim Dandy Winterberry is dense and compact. Adaptable to wet soils, but tolerates more normal conditions also. Native habitats are swampy areas. Leaf spot and mildew can be serious problems. Develops chlorosis on alkaline soils.
Tree Indiana Native Juglans cinerea [Butternut] Juglans cinera is a large, rounded tree similar to, but overall smaller than the Black Walnut (Juglans nigra). It is not commonly grown for ornamental purposes. The nut, once one is able to crack the hard shell, is edible, sweet, oily, and buttery. Long tap root makes transplanting difficult. This species is valued for its wood and between overharvesting and losses from Butternut Canker (Sirococcus clavigignenti-juglandacearum), this species has become rare in its native habitat.
Tree Indiana Native Juglans nigra [Black Walnut] Nuts are a serious litter problem, staining sidewalks and driveways. Juglone (found in leaf litter and possibly roots) is toxic to many plants, like tomatoes, blackberries, red pines, and many others. Black Walnut wood is valuable and has a variety of commercial uses, especially for furniture.
Tree Juglans regia [Persian Walnut] Juglans regia is a large, rounded, spreading tree that produces the walnuts frequently seen in stores. It may take up to 20 years for this tree to become mature enough to produce a decent-sized crop of nuts. Long tap root makes transplanting difficult.
Shrub/Tree Juniperus scopulorum 'Skyrocket' [Skyrocket Rocky Mountain Juniper] 'Skyrocket' has an extremely narrow, fastigiate form and silvery blue-green foliage. Widely adapted to soils and climates. Does well in alkaline soils, but not wet soils. Alternate host for cedar-apple rust disease. Plant other juniper species in areas having many apples, hawthorns, etc. Susceptible to bagworms.
Shrub/Tree Juniperus scopulorum 'Welchii' [Welch Rocky Mountain Juniper] 'Welchii' is compact and comlumnar with blue-green foliage that is silver when emerging. Widely adapted to soils and climates. Does well in alkaline soils, but not wet soils. Alternate host for cedar-apple rust disease. Plant other juniper species in areas having many apples, hawthorns, etc. Susceptible to bagworms.
Shrub Juniperus virginiana 'Grey Owl' [Grey Owl Eastern Redcedar] 'Grey Owl' is compact, broad, wide-spreading evergreen, female shrub with glaucous gray-blue foliage and an abundance of blue berries (cones). Widely adapted to soils and climates. Does well in alkaline soils, but not wet soils. Alternate host for cedar-apple rust disease. Plant other juniper species in areas having many apples, hawthorns, etc. Susceptible to bagworms.
