Fall Colors Mark Seasonal Change
The changing of the seasons, especially from summer to fall, is a welcome transition, bringing cool, crisp mornings and cooler days.
One of the first signs of summer's end is the yellowing of cottonwood tree leaves, soon followed by the vibrant reds and oranges of maples and oaks.
While New England is renowned for its fall foliage, Kansas also boasts a impressive display of autumn colors.
Why Trees Change Colors
A recent article from the Horticulture Department explores the science behind the changing colors of trees, revealing that specific plant pigments determine individual colors.
- Chlorophyll, which captures the sun's energy, gives foliage its normal green color.
- Other pigments produce the striking colors of fall, including red, purple, yellow, orange, and brown.
Part of the allure of fall foliage is color variation.
