Why leaves turn color in the fall:
The carotenoids (pigments in the photosynthesizing cells), which are responsible for the fall colors, are present in the leaves during the growing season. However, the colors are eclipsed by the green chlorophyll. Towards the end of summer, when the chlorophyll production ceases, the other colors of the carotenoids (such as yellow, orange, red, or purple) become visible.

Wormwood defined:
Artemisia absinthium, known as wormword, is a hardy, spreading, fragrant, perennial, 2 to 4 feet (61 to 122 centimeters) tall. It can and is still used as a bitter tonic and is native to Europe but can also grow in North America.
