The zone number which we give is the northern- 

 most zone in which we believe the plant to be hardy 

 under average winter conditions. It should be noted 

 that a plants ability to survive the winter is not de- 

 termined solely by the minimum temperature to 

 which the plant is exposed but is also affected by the 

 plant's general health, the soil moisture content, and 

 the exposure to scalding sun and wind. Our assign- 

 ment of a particular zone number to plant should 

 not be construed as a guarantee that the plant will 

 survive in that zone. We can make no warranty ex- 

 pressed or implied, as to the ability of any plant to 

 survive after it has left this nursery.
