Tree Ilex opaca 'Old Heavy Berry' [Old Heavy Berry American Holly] 'Old Heavy Berry' is an excellent, vigorous female cultivar with good winter hardiness and an abundance of large, bright red fruits. 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 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.
Tree Juniperus chinensis 'Mountbatten' [Mountbatten Chinese Juniper] 'Mountbatten' is a hardy, dense, and narrow cultivar with silver-green needles. Widely adaptable to soils and climates. Tolerates alkaline soils, heat, and drought. Members of this species are used from New England to Minnesota to Louisiana. Phomopsis and Kabatina blights can be a serious problem in some areas, especially for small plants.
Tree Indiana Native Juniperus virginiana [Eastern Redcedar] Widely adapted to soils and climates, as evidenced by the species' wide geographic range. 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.
Tree Juniperus virginiana 'Burkii' [Burk Eastern Redcedar] 'Burkii' is a pyramidal male cultivar with glaucous silvery blue 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.
Tree Juniperus virginiana 'Canaertii' [Canaert Eastern Redcedar] 'Canaertii' is a picturesque, pyramidal female cultivar that produces a profusion of bloomy 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, and 'Canaertii' is especially susceptible. Plant other juniper species in areas having many apples, hawthorns, etc. Susceptible to bagworms.
Tree Juniperus virginiana 'Cupressifolia' [Hillspire Eastern Redcedar] 'Cupressifolia' is a pyramidal female cultivar with bright yellow-green, cypress-like 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.
Tree Juniperus virginiana 'Glauca' [Silver Eastern Redcedar] 'Glauca' is a columnar cultivar with glaucous blue needles that are most prominent in the spring, transitioning to blue-green later on in the summer. 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.
