What makes leaves turn different colors in autumn?  According to the College of Environmental Science and Forestry:  http://www.esf.edu/pubprog/brochure/leaves/leaves.htm … “During the spring and summer the leaves have served as factories where most of the foods necessary for the tree’s growth are manufactured. This food-making process takes place in the leaf in numerous cells containing chlorophyll, which gives the leaf its green color. This extraordinary chemical absorbs from sunlight the energy that is used in transforming carbon dioxide and water to carbohydrates, such as sugars and starch. Along with the green pigment are yellow to orange pigments, carotenes and xanthophyll pigments which, for example, give the orange color to a carrot. Most of the year these colors are masked by great amounts of green coloring. Chlorophyll breaks down. But in the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.” 

So there is the scientific explanation for the color changes in a leaf.  I have a seasonal love that by-passes all the science stuff … oh, autumn!  These cooler days and color-bursting leaves bring me outdoors at every opportunity.  This past Saturday Dean and I watched bright orange pumpkins drop from the blue sky while small engine and military war planes whirl above with the leaves and birds.  Sunday afternoon gave us another chance to enjoy the vibrant reds, oranges, and yellows at Boone Hollow Farm while picking the last of our ripened cherry tomatoes and all the green tomatoes still on the vines which succumbed to the first killing frost this past week.  This Monday’s lunch hour was spent walking at the park relishing more color and sunshine.  Tuesday promises even more golden sunshine and warmth.  And on  a rainy, colder Wednesday the trick or treaters will come out in their costumes.  Some will be dressed in black and gruesome red, black, and green makeup, but I particularly like the happy get-ups in bright colors and smiles.  Our 2-year old granddaughter, Elise is dressed as a monarch butterfly!
