Honey fungus-resistant plants are those varieties that resist mushroom root rot (commonly referred to as honey fungus) caused by an Armillaria fungi. One of the most widely destructive fungal infections in natural woodlands and gardens, honey fungus is a fatal disease of numerous trees and shrubs with a display of mushrooms and ensuing plant tissue decay. Choose resistant plants like the dawn redwood tree for prevention of infection and plant death.
Dawn Redwood Tree
Dawn redwood trees (Metasequoia glyptostroboides) are honey fungus-resistant deciduous trees that appear to have evergreen foliage. The trunk is an orange/brown hue, and the foliage includes green, needle-like leaves that become yellow to orange during the fall season. Growing in a pyramidal shape, dawn redwood trees are suitable for use in urban areas. This tree is also resistant to verticillium wilt and many other pests and diseases. Thriving in full sunlight, dawn redwoods prefer slightly acid soil and are highly tolerant to wet sites, clay soil, drought, well-drained sites and loam, according to the University of Florida IFAS Extension. Dawn redwoods grow to a height of 70 to 90 feet with a spread of 15 to 25 feet; plant this tree in USDA hardiness zones 5A to 8B.
Tuliptrees (Liriodendron tulipifera), also referred to as tulip-poplar trees or yellow-poplar trees, are honey fungus-resistant deciduous trees that display fragrant yellow-green flowers resembling tulips and green foliage that becomes yellow during the autumn season. Bloom time is during the middle of spring, according to the U.S. Forest Service. Though tuliptrees resist honey fungus, they are susceptible to other diseases, such as vericillium wilt. With soft wood and a symmetrical ovular shape, tuliptrees thrive in full sunlight and prefer well-drained soil with an acid pH. Tuliptrees grow to a height of 80 to 100 feet and a spread of 30 to 50 feet. Plant in USDA hardiness zones 5 to 9A.
Maidenhair trees (Ginkgo biloba), also referred to as ginkgo trees, are deciduous trees highly resistant to pests and diseases, including honey fungus attack. Displaying green foliage in an irregular, dense shape, maidenhair trees put on a vivid show of bright yellow leaves during the fall season accompanied by a fast drop of leaves, according to the University of Florida IFAS Extension. Resistant to damage from storms as well, maidenhair trees are sturdy and appropriate for urban planting. Thriving in full sunlight to partial shade, this honey fungus-resistant plant will grow successfully in nearly any type of soil. Maidenhair trees reach a height of 50 to 75 feet with a spread of 50 to 60 feet; plant in USDA hardiness zones 3A to 8A.
