What Zone is Highlands?

​

I have always planted as if I am in Zone 6, however the Zones changed in 2023. Highlands is now 7a.  Several experienced local gardeners say they have garden spots that are Zone 5.

​

What are zones and why do we care about them?

​

The US Department of Agriculture Plant Hardiness Zone Map defines 11 bands across the nation according to average annual minimal temperatures.  The average coldes temperatures for Zones 6 and 5 are:

​

•            -10 degrees to zero degrees Fahrenheit in Zone 6

•            -20 degress to -10 degrees Fahrenheit in Zone 5

​

The cold hardiness of a perennial plant - the minimum temperature the plant will tolerate before experiencing cold damage - is indicated by the zones where the plant grows.

​

All of the perennial plants sold at the Mountain Garden Club's plant sale can survive and thrive in Zone 5, 6 and 7. 

​

Use zone information as a guide, not an absolute.  You may have microclimates in your garden where certain plants "winter over" better than others.  Varietal differences, soil condition, drainage, sunlight, wind exposure, mulch - as well as proper fertilizing and watering - also determine which plants will do well for you.

Enjoy!
