I used the camera's digital zoom for a close shot of the sun hitting and shining through White Oak leaves near the canopy of a large, old Oak tree. I did crop the photo a bit. But I didn't adjust the exposure or tint in any way. It shows how, on a sunny day and at certain angles, Oak leaves are every bit as vibrant as Maple leaves.

The shot above is a different one--without zoom--of the same leaves and the tree at a greater distance to show that it really did happen.
|Morning sun shining through Cercis canadensis foliage|
Many of our trees' leaves have fallen or blown off with the wind and rain. But not before I snapped a few images showing the effects of strange light angles, mutations, and pigment imbalances.
|Uneven sunlight effects on Syringa meyeri|
The Dwarf Korean Lilac bush had a diagonal line running through the middle of its foliage. I'm guessing the reason was that one side was shaded by the house, while the other was exposed to more sun throughout the day. Weird, but fascinating, isn't it?
|Mixed hues on Berberis thunbergii|
The same kind of thing happened with the Pygmy Barberry. Part of this might be due to stress: The rust-colored leaves are near the driveway.
|Forsythia 'Courtasol' frost-nipped?|
Perhaps frost nipped the tops of the Dwarf Forsythia, yielding uneven foliage coloration?
|Variegated foliage on Dendranthema grandiflora|
I don't know why the leaves on some of my Mums are discolored while their neighbors are still green--stress, maybe?
|Dendranthema grandiflora "sport"|
If you clicked on this post for sports coverage based on the headline, this flower is all I have to offer. Sorry about that. I've been wondering why some of my Mums changed from yellow to pink. Research brought me to this webpage describing this phenomenon: "Sports: Plant Mutations."
Several other links I came across while researching this post effectively explain the science of foliage coloration and autumn plant changes:
- The Science of Color in Autumn Leaves;
- The Chemistry of Autumn Colors; and
- Top Trees and Shrubs for Fall Color.
It's fascinating stuff about the chemical and biological changes that take place in "simple" leaves.
Switching gears a bit, I'm honored that Jason and Judy at Gardinacity nominated me for the Beautiful Blogger award. To accept the award, I'm supposed to name seven interesting facts about myself. "Interesting" is a subjective thing, but here goes:
1. I nearly died as an infant. I forget if it was because of a bad case of pneumonia or my allergy to penicillin.
2. I'm distantly related to former Pres. Millard Fillmore and TV journalist Tom Brokaw.
3. My maternal grandmother was a Baptist preacher when female clergy were uncommon.
4. My paternal English great-grandfather and his family had planned to sail for and resettle in Australia, but got on a ship to America instead.
5. I have strong digestive reactions to Cantaloupe, Broccoli, and Avocado, but I don't know why. All were favorites before I figured out which foods were triggers.
6. Favorite food: BLT, but only with fresh garden Tomatoes and Lettuce.
7. Favorite classical piece: Symphony No. 2 in D major, by Jean Sibelius.
I'm supposed to nominate others for this award. As my blogroll is down because of warnings on the Web about sidebar spam, I nominate all bloggers who are my favorites on Blotanical. The blogroll will be back up soon--with even more wonderful blogs listed!
Thanks for the honor, Jason and Judy!
