Eucalyptus tenuiramis - Silver Peppermint (Tasmania) A medium-sized tree which comes from drier sites and poorer soils in northern and eastern Tasmania.  It is a very beautiful tree, with smooth cream-colored bark with some grey patches, and pendulous shiny silvery-green leaves.  The first few sets of juvenile leaves completely encircle the stem in the same manner as E. perriniana, but slightly different.  Reasonably fast-growing to about 50 - 60', and requires good drainage.  Hybridizes and intergrades with E. coccifera.  Probably hardy to around 6 - 14°F.
