Eucalyptus viminalis, commonly known as Manna Gum, Ribbon Gum, or White Gum, is an essential member of the endangered Ribbon Gum – Mountain-gum – Snow-gum grassy forest/woodland community. This remarkable tree species is often found thriving alongside Mountain Gum (E. dalrympleana) and Snow Gum (E. pauciflora) or standing in mono-dominant formations across the Northern Tablelands bioregion. Towering at heights of up to 130 ft under ideal conditions, Manna Gum favors diverse landscapes, predominantly thriving on basalt-derived substrates, but also on sediments and meta-sediments.
The distinct shedding bark, which gracefully cascades in long strips, reveals a smooth, white surface underneath, occasionally tinged with hues of yellow or pink. Manna Gum features lanceolate, glossy green leaves that add to its visual appeal. This gum species is diverse, with juvenile leaves identifiable by their unique lanceolate to broad-lanceolate shape.
Manna Gum produces creamy-white, nectar-abundant flowers that captivate various bird species. An integral part of the ecosystem, the tree also offers important habitat and food for small mammals and koalas. Its sugary-white exudate ‘manna’ is a delight for many species, providing sustenance and supporting biodiversity.
Ideal for planting in windbreaks and shelterbelts, Eucalyptus viminalis showcases resilience and adaptability. Whether serving as a vital ecological component or an aesthetic addition to the landscape, this iconic species represents the extraordinary biodiversity and natural beauty of its native regions.
