Hardiness

To encourage wider successful planting most of the species offered are from parent trees from mountains, exposed plains or frost pockets.  In some cases the environment they experience here is kinder than their natural habitat.  UK Forestry Commission research and our experience shows that the majority are hardy down to between minus 14°c and minus 18°c.  In the Snowy Mountains some parent trees experience up to 215 frosts a year with no month completely frost free.  In fact during the severe winter of 1981/2 when Britain experienced some of the lowest winter temperatures ever recorded, Eucalyptus debeuzevillei and Eucalyptus niphophila survived -23°c in Northumberland.  You may remember that many other so called hardy plants did not survive that exceptional winter, which was the worst for 36 years.

Hardiness increases as the leaves change from juvenile to adult and the stem girth increases.
