The resistance of evergreens

Evergreens will keep most of their leaves during the autumn and winter. Resistance to cold and moisture loss occurs with special leaves such as the long thin needles of the pine and fir trees. And then there are evergreens with broad leaves  or with tough, waxy surfaces like the holly. While these evergreens are able to continue to photosynthesize during the cold weather with shorter daylight hours,
their reactions will be slower.
