Tall southeastern Australian eucalypt reaching 50 m, with bark that shreds in long ribbons and sweet manna-like sap exudates that solidify on the bark. The principal food tree of the koala across its southern range.

| System | Rating | Temperature range | How to read it |
|---|---|---|---|
| USDA hardiness zone | Zone 7–10 | −17.8 °C to 4.4 °C | Plant tolerates down to this zone |
| RHS hardiness rating | H4 | −10 °C to −5 °C | Plant needs at least this level of cold tolerance |
| Canadian plant hardiness zone | Zone 8–9 | −7 °C and warmer | Plant tolerates down to this zone |
| Australian (ANBG) zone | Zone 2–6 | −10 °C to 15 °C | Plant tolerates down to this zone |
Growing notes
- Excellent tall windbreak for cooler southern Australian and inland conditions where Tasmanian blue gum is too vigorous or salt-demanding
- Distinct from Tasmanian blue gum Eucalyptus globulus (already in the database) — manna gum is faster-growing, hardier in frost, and the principal koala food tree of Victoria and southern New South Wales
- Strips of shed bark hang from the branches and accumulate at the base — both a fire risk to be managed and an iconic visual feature of the species
- Sweet white manna-like exudate on the bark in summer gives the common name
Pet caution: Manna gum (Ribbon gum) is listed as potentially harmful to cats and/or dogs. Keep pets from grazing on it, and contact a vet if you suspect your animal has eaten some.
