The zone number which we give is the northernmost 
zone in which we believe the plant to be hardy under ave- 
rage winter conditions. It should be noted that a plant’s 
ability to survive the winter is not determined 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 assignment of a particular zone number to a 
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 SUIVIVe 
after it has left this nursery.
