On This Day:
Tuesday April 21, 2015 This is the 111th day of the year, with 254 days remaining in 2015. Fact of the Day: leaves The pigments in leaves (carotenoids) which are responsible for the fall colors are actually present in the leaves all during the growing season of spring and summer. The colors are eclipsed by the green chlorophyll. Toward the end of summer, chlorophyll production stops and the colors of the carotenoids (yellow, orange, red, purple, etc.) become visible. Different trees turn different colors, e.g. sugar maple and sumac turn flame red and orange; popular, birch, tulip trees, and willows turn yellow.
