Blossoming chestnut trees

Different brushstrokes In Blossoming chestnut trees, Van Gogh experiments with brushstrokes. He applies the green of the trees with flat strokes, while giving structure to the foliage with short, straight, dark blue brushstrokes. On some of the white tapers, he places thick dark blue contours, which enclose the blossom like a kind of gabled roof. Unpainted He paints the sky with overlapping zigzag strokes, a soft version of the sharp stripes in the tree.
