You remember that poem, by Robert Frost?

"Nature's first green is gold,
Her hardest hue to hold.
Her early leaf's a flower;
But only so an hour.
Then leaf subsides to leaf.
So Eden sank to grief,
So dawn goes down to day.
Nothing gold can stay."

Well, in my winter garden, Nature's first green is actually purple.
