Suddenly, after a few cold nights, and noticeably shorter days, fall colours are appearing in the trees. Young silver and sugar maples are one of the earliest to turn, and among the brightest orange or red. This is a young silver maple that we planted in our meadow.
One of my favourites is the sumach. Growing in dense large clumps that shade out anything else, it forms bright red masses of compound leaves like this one. A few branches will turn red first, and then slowly the rest of the sumachs turn til they're a bright red feature in the landscape for a week or two.
The large round heart-shaped leaves of the basswood turn yellow. Young saplings, like this one, turn before the mature trees do. Together all these leaves paint the trees in a burst of colour before the leaves finally drop and summer ends.
