Dear 100 Hour Board,
Why is it that some broadleaf evergreens turn red during the winter? For instance, despite its name, Wintergreen turns red during the winter. Is it just that they don't need as much light during the winter because they don't grow as much?
Also, will Wintergreen do well here in northern Utah?
There are several different types of chlorophyll. The most prominent type is green in hue, but others are orange, yellow, and red. Since the green color is the most sensitive to temperature, it leaves the leaves first. That is also why the leaves turn colors in the autumn.
Wintergreen plants are supposed to grow well in Zones 5 through 7. This means that it should grow fairly well in Utah. See a growing zone map at http://sonorasgardens.com/growing_zones.htm.
