Eucalyptus Red Box Gum - Eucalyptus polyanthemos

• Rounded juvenile leaves in blue-green hues are highly ornamental and widely used in the cut-flower trade across Australia.

• High drought tolerance once established, one of the most water efficient large native trees available for Australian gardens and streetscapes.

• Tolerates heavy frosts and strong winds, rated high for both, making it suitable for exposed sites, alpine foothills, and cold inland regions of Victoria

• White spring flowers are a significant nectar source for honey
production and attract honeyeaters, lorikeets, and native bees.

• Broad domed to upright canopy suits street planting, windbreaks, shade trees, parks, and large native gardenplantings.

Eucalyptus polyanthemos is one of the most versatile large Australian native trees for public and private landscapes. Its combination of toughness, ornamental foliage, and broad habitat value makes it suitable for a wide range of planting scenarios:

• Street and verge planting: One of relatively few native trees recommended for planting under power lines.Suitable for broad streets and open verges where canopy clearance is available. Not suitable for narrow nature strips.

• Windbreak and shelter belt: High wind tolerance makes it an excellent choice for rural and semi-rural windbreak plantings across Victoria.

• Large garden shade tree: The broad domed canopy provides generous shade for large residential gardens, acreage, and rural properties across southeastern Australia.

• Native and habitat garden: A cornerstone species for wildlife-focused native plantings, pairs well with Banksias, Grevilleas, Acacias, and other Victorian indigenous species.

• Park and open space planting: Widely used in parks, reserves, and public open space across Victoria.

• Honey and productive landscape: An important species for apiarists and productive native gardens. The white spring flowers are a significant and reliable nectar source.

Q: What fertiliser should I use for Eucalyptus polyanthemos?

Always use a low-phosphorus, slow-release fertiliser formulated specifically for Australian natives. High-phosphorus fertilisers can cause phosphorus toxicity in Eucalyptus and other Myrtaceae species, leading to poor growth and potential plant death.

Q: How is Eucalyptus polyanthemos used in the cut-flower industry?

The distinctive rounded, blue-grey juvenile foliage of Eucalyptus polyanthemos is highly prized by florists and widely used in floral arrangements and bouquets across Australia. Coppicing or hard pruning of selected stems encourages the production of juvenile foliage for cutting.

Q: What pests affect Eucalyptus polyanthemos?

Common pests include borers, caterpillars, and myrtle rust. Healthy, well-established trees typically show good resilience to pest and disease pressure. Monitor young trees closely during establishment and treat severe infestations with appropriate organic or targeted sprays.

Q: How drought tolerant is the Red Box?

Eucalyptus polyanthemos has high drought tolerance, making it one of the most water-efficient large native trees for Australian gardens. Once established typically after 1-2 years, it requires minimal supplementary irrigation even through Melbourne's dry summers and inland Victorian droughts.
