This was painted in 1889 while Van Gogh was at the Saint Paul Asylum. While there he painted many paintings of the doctors, the asylum, and the gardens. He sent some paintings to his brother when he wrote to him, and out of all the paintings this was one of his favorites.
I love the colors in this painting probably because of how much I love fall. Apparently Van Gogh painted this during one of his more happy days commenting on how beautiful the leaves looked this time of year.
