Eucalyptus pulchella, the white peppermint, is a slender Tasmanian gum with fine, glossy green leaves that smell strongly of peppermint when crushed. Smooth white to pale grey bark sheds in ribbons down the trunk, and clusters of small white flowers open through summer above an airy, finely textured crown.
Plant it in full sun in almost any well drained soil. Growth is fast, around 50 centimetres to 1 metre a year, and established trees handle dry summers along with light to moderate frost. It suits temperate and cool temperate districts across Tasmania, Victoria, the southern tablelands and the Adelaide Hills.
The narrow, upright habit makes it useful where height is wanted without a heavy canopy, so avenues, shelterbelts, civic plantings and larger residential blocks all suit it. It also carries revegetation work well. Plant 3 metres apart for an avenue, or 3 to 4 metres as specimens. The fine crown casts light shade, so planting beneath it still grows.
Frequently Asked Questions
About White Peppermint
What is Eucalyptus pulchella?
White peppermint is a Tasmanian eucalypt with a slender upright trunk, smooth white to pale grey bark that sheds in ribbons, and fine glossy leaves that release a strong peppermint scent when crushed. Small white flowers open in summer. It is evergreen, fast growing and hardy once it has a season or two behind it.
How tall does White Peppermint grow?
Mature trees generally reach 10 to 20 metres with a spread of 4 to 8 metres, depending on soil depth and rainfall. The crown stays fine and open rather than heavy, so the tree reads as tall and light. On shallow or dry sites it settles at the lower end of that range.
How fast does it grow?
Fast, at around 50 centimetres to 1 metre a year while young. The quickest growth comes on deep, well drained soil in full sun with water through the first two summers. Because it moves quickly, formative pruning in the first few years is worth doing to set a single straight leader.
Is it evergreen or deciduous?
Evergreen. It holds foliage year round and does not drop its leaves seasonally, though like all eucalypts it sheds bark ribbons and some older leaves through the warmer months. That makes it useful where year round shelter or screening is needed rather than seasonal cover, particularly on exposed rural boundaries.
When does it flower?
Through summer, roughly December to February, with clusters of small white flowers held across the crown. The flowers are nectar rich and draw honeyeaters, native bees and other insects, so it earns its place in habitat and revegetation planting. Flowering is heavier on mature trees in an open, sunny position.
Is it drought and frost tolerant?
Established trees handle extended dry periods without irrigation, which suits inland and rain shadow sites. Frost tolerance covers light to moderate frost once the tree has settled in, and young stock planted in a cold hollow benefits from protection for its first winter. Sharp drainage improves both drought and cold performance.
How do I care for White Peppermint?
Water weekly through the first two summers, then rely on rainfall. Mulch well and keep grass off the root zone while the tree establishes. Prune in late winter to remove competing leaders and to lift the crown for clearance. Avoid high phosphorus fertiliser; a light native feed in spring is enough.
