Wondering where to see the best autumn colors in the state? Check out Visit Indiana's Leaf Cam and see for yourself.
Visit Indiana has five webcams of outdoor scenes in Fort Harrison State Park in Indianapolis, French Lick Resort, Brown County, the Corydon Capitol State Historic site and Spring Mill State Park in Mitchell - some of the best places to see the leaves change in the state.
Indiana's forests are a mix of various deciduous trees whose deep summer greens turn various hues of red, purple, orange and yellow. Why this seasonal change? The answer lies within their pigment.
There are three pigments found in all leaves that affect fall color:
The change in weather also plays an important factor. As autumn approaches and the days shorten, trees are reminded that winter is coming. With less and less sunlight to encourage photosynthesis, chlorophyll production slows until it stops. The trees go into a period of rest, or dormancy, and survive through the winter by living off the food they had stored during the summer months. Only when chlorophyll ceases production will carotenoids and anthocyanins become visible and show their bold colors.
Temperature and precipitation also influence the degree of how bright the fall color is and how long it will last. Low temperatures - above freezing - will produce more anthocyanin and bring out the bright reds; frost, however, will weaken the red hue. Though not the most preferable weather to go out and walk among the autumn trees, rainy and overcast days tend to bring out the intensity of fall colors. So bring an umbrella when hoping to capture the most brilliant of autumn scenes!
Certain colors are characteristic to particular species of trees. The timing of the color change also varies by species, so don't expect to see all our deciduous trees change at once. The list below is just a few colors found on trees found throughout Indiana's landscape.
Enjoy the color while you can! Autumn colors occur for a brief period; peak colors generally develop in late September and can extend from October through early November.February 21, 2013
