E. globoidea: information for growers

Eucalyptus globoidea (White stringybark) is a species which grows well across a range of sites, and produces Class 2 durable timber which is heavy, versatile and attractive. E. globoidea has good natural form and self-pruning ability. It is the first NZDFI species for which a growth model has been produced. 

Site requirements

  • Frost tolerance: Minus 5 degrees (avoid very cold sites).
  • Rainfall min and max:  800 - 2500 mm/year.
  • Soil type/drainage: Suited to a wide range of soils except skeletal and stony soils.
  • Wind tolerance: One of the more wind-tolerant durable eucalypts (all eucalypts grow better on sheltered sites).

Matching eucalypt species to site is essential for good tree survival and growth. E. globoidea is a versatile species, and can already be found growing well in a range of New Zealand locations. Watch our video below, make sure you know your proposed planting site, then ideally talk to an experienced grower or nurseryman before purchasing trees.

Establishment and silviculture

Follow our establishment guidelines for good establishment success.

E. globoidea requires form pruning. Little clearwood pruning should be necessary if growing post and pole wood. For high quality sawlogs, clearwood pruning at an early age is necessary.

Read our form-pruning guidelines and watch some videos.

Pest and disease threats

E. globoidea  suffers less from insect and possum browse than some other eucalypt species.

Timing of flowering/potential to support bees

Summer/autumn flowering but with one winter record (Marlborough). Flowers regularly and yields good quantities of pollen and but not so much nectar. Good flavoured amber honey.

Growth models for E. globoidea

Research by successful PhD candidate Serajis Selakin led to the development of some early growth models for E. globoidea:

Hybrid growth models for E. globoidea and E. bosistoana (Salekin 2019)

Further models have since been developed - information about these is available in our Strategy document (Section 5).

Timber properties and markets

Two NZDFI PhD projects at the School of Forestry are currently focusing on E. globoidea timber properties.


Note:  Durability is a complex parameter; NZDFI’s research into heartwood formation will improve our understanding of factors determining durability.


  • Heartwood is dark brown/pink
  • Sapwood pale brown/pink
  • Moderately fine texture with straight grain


Structural uses, poles and posts, crossarms, railway sleepers, vineyard and fence posts. Also has potential as a flooring and furniture timber.

NZDFI anticipates E.globoidea will be highly suited as a component of high strength engineered wood products such as laminated veneer lumber (LVL) and cross laminated timber (CLT).

Watch this powerpoint presentation about research into E. globoidea's veneer potential.

More information

Natural range

E. globoidea has a wide natural range through eastern New South Wales except the far north, and eastern Victoria except in areas where summers are too cool. It is found at altitudes of 0-1100 metres.

Cultivation in New Zealand

E. globoidea was selected for the NZDFI breeding programme based on its consistent performance across a range of sites.

There is considerable experience with E. globoidea on milder areas in New Zealand, where it has grown well for many decades. It is not a fast initial grower but it is a consistent grower.

Form is generally good although on fertile sites there may be a propensity to form double leaders.

E. globoidea is performing well in early NZDFI trials (2003-04 plantings) in Marlborough and Canterbury, and various other trial plantings.

Genetic improvement of E. globoidea by the NZDFI

E globoidea is a leading species in NZDFI’s breeding programme. NZDFI has established over 160 families  for intensive genetic improvement over the next few years. There had been no genetic improvement of this species before the NZDFI programme.
