As a gardening term, evergreen means the foliage remains on all year, whether it is needles or leaves. Many plants have a wide range of hardiness and can manifest as an herbaceous perennial that is not evergreen at the lowest end of their range, to a large woody entity that does always have leaves at the warmest end.
So if you are attracted to a plant reported as evergreen but the lowest zone for it is the zone you are in, it would be a good idea to ask if that particular plant is evergreen in your zone.
If you don't know your zone, you can find it here:

If you are not familiar with hardiness zones, please ask and the members can explain that too. Best luck!
