I imagine that if people were asked to name the leaves that produced the brightest colours in autumn most would mention the Acer, a tree that has been bred specifically to produce colourful leaves. However, this autumn, though I've photographed my share of Acers, I've also come across a leaf that could well be brighter than the brightest acer. I don't know the variety of Cotinus (also known as Smoke Bush) shown above, but I do know that its leaves "out-glow" most Acers. I came across this one growing behind a school fence, stretching towards the pavement seeking light.
