Snow Gum

Eucalyptus pauciflora

“The cold-hardiest eucalyptus on Earth. Survives Zone 6. Twisted white sculptural bark.”

Most eucalyptus die at the first hard freeze. Snow gum laughs at it — native to the Australian alps, it survives -4°F regularly and brief dips even lower. The bark sheds to reveal smooth gray-white and cinnamon-brown patches. Twisted trunk, often multi-stemmed from wind exposure in its native range. Grows Zone 6–10. If you want the alien quality of eucalyptus without the frost vulnerability, this is the tree.
