WINTER HARDY/ZONALITY

Winter hardiness / zonality data show the lowest temperature (measured in °C), that a given plant can
withstand without further damage.

 
Zone Temperature in °C Notes
Z1 <  to - 45,5  
Z2 from -  45,5 to - 40,1  
Z3 from - 40,0 to -34,4  
Z4 from - 34,3 to -28,9  
Z5 from - 28,8 to -23,4  
Z6 from - 23,3 to -17,8 Need some winter protection in areas not covered with snow.
Z7 from - 17,7 to -12,3 Need some winter protection in areas not covered with snow.
Z8  from - 12,2 to -6,7 Covering with leaf mold, even just a heap o leaves or twings to provide crucial                                              insulation for the plants is essential.
Z9 from - 6,6 to -1,2 Winter protection with thick leaf mold or geotextile, or possibly put it in a cold bed.
Z10  from - 1,1 to +4,4 Protect your plants in winter by putting it in a frost-free greenhouse or a wintergarden.
Z11 from +4,5 to +40,0 If possible, put the plant in the house or in a winter garden above 12°C.


The temperature data and zones show non the zoning map are based on measurements that give the lowest
average winter temperature in the area with an 80% probability.
