Honey Fungus-Resistant Vegetation: A Look at Flora with Immunity to These Fungal Infections
Resistant Plants: A Guide to Gardening in the Presence of Honey Fungus
Gardening enthusiasts in the UK may face the challenge of honey fungus, a soil-borne fungal pathogen that can wreak havoc on plants. However, not all hope is lost. This article provides a list of plants that are generally resistant to honey fungus, along with some tips to minimize the risk of this fungal disease.
Many ferns can tolerate honey fungus infection, making them a good choice for your garden. Ferns are not only resistant to honey fungus but also add a touch of elegance to any garden setting.
Grasses and herbaceous perennials, such as Coral Bells (Heuchera), are also known to show some tolerance to fungal diseases. Although the source [1] discusses pest resistance rather than specifically honey fungus, these plants are generally robust and can withstand various garden challenges.
Some shrubs like Honeysuckle (Lonicera) have resistant varieties against powdery mildew, a fungal disease related in habitat to honey fungus. This suggests that these shrubs may also have some degree of resistance to honey fungus [2].
Certain woody plants, such as Peonies, can be more pest and disease resistant compared to roses, which are vulnerable to several pests and possibly honey fungus [1]. It's recommended to avoid susceptible plants like Buddleja globosa, which is specifically mentioned as susceptible to honey fungus [5].
In general, plants resistant to honey fungus tend to have good drainage requirements, strong root systems, and do not easily develop wood rots. For best long-term results, planting species with good air circulation, well-drained soil, and avoiding overly shaded or moist conditions helps reduce honey fungus risk. Mulching and soil health also play a role in preventing disease [3].
In addition to the plants mentioned above, Boxwood (Buxus spp.), Lavender (Lavandula spp.), Rhododendrons and azaleas, Lilacs (Syringa spp.), Japanese maple (Acer palmatum) in some instances, certain conifers like pines and firs, and some Phlomis species are also known to be resistant to honey fungus from horticultural expertise [4].
When it comes to checking for honey fungus, look for signs of decay and white fungal material beneath the bark at the collar of the plant where the roots and stem meet. Digging in the soil around affected plants will often reveal the dark, bootlace threads [6].
For highly specific plant choices in your region, consulting local horticultural extension services is advised. Despite honey fungus preventing the growth of many plants, there are just as many, if not more, plants to replace them with. Some examples include Salvias, Japanese quince (Chaenomeles japonica), Yew (Taxus baccata), and Smoke bush (Cotinus coggyria) [4].
Lavender, a member of the Lamiaceae family, is generally resistant to honey fungus and provides spikes of fragrant, nectar-rich flowers in summer. The common myrtle (Myrtus communis) is another resistant plant, bearing fragrant white flowers in late summer and having good drought tolerance [6].
It's important to note that honey fungus (Armillaria) is a common issue in the UK, with Armillaria mellea and Armillaria gallica being the most encountered species. Honey fungus has the ability to kill old and majestic trees and shrubs, which can be a real issue for orchard owners [7].
By choosing resistant plants and maintaining a healthy garden environment, you can minimize the risk of honey fungus and enjoy a beautiful, thriving garden.

A home-and-garden lifestyle that focuses on planting resistant plants can help mitigate the impact of honey fungus in your garden. For instance, Lavender and many fern species are known to be resistant to this fungal disease.
