Glowing Frost-Edged Blackberry Leaf

[best appreciated at full size against black]

Blackberry bushes grow in a few places on our property and I found this leaf on a bush that gets more direct sunlight than the bushes which grow behind our shop and are usually in deep shade. Did you have any idea how colorful blackberry leaves can be? I certainly didn't! Here is one in tones of gold and rust, back-lit by sunshine and edged by frost.
