What the species is and where it came from
Eucalyptus is a genus of over 700 flowering plant species in Myrtaceae, most native to Australia—with representation in every state and territory—and a few native to islands north of Australia, including E. deglupta in the Philippines.
How it works, in terms someone would actually use
Eucalyptus species photosynthesize through bark when foliage is lost; one species, E. globulus, re-fixes internal CO₂ via bark cells after partial defoliation.
What it gets right
It gets right the physiological adaptation of bark photosynthesis under stress, and the structural capacity for extreme height in temperate forest ecosystems.
What it does not
It does not establish native range beyond Australia, islands north of Australia, and the Philippines; it does not occur natively in Europe, North America or Africa.
What it changed
It changed how we measure height in angiosperms: E. regnans holds the global record at 100.5 m, and E. diversicolor holds the European record at 72.9 m.
Who it is for, and who it is not
It is for botanists, foresters, and field naturalists who track height records, bark physiology, or non-native tree performance; it is not for gardeners seeking low-maintenance ornamentals or conservationists focused on endemic island flora.
Is it worth your time
Yes—if you want to see the tallest flowering plant on Earth, or a non-native tree taller than any native European tree.
