The artist began painting almost as soon as he had arrived at the psychiatric hospital of Saint-Paul de Mausole in Saint-Rémy.[4] Among his first subjects were the irises and lilac bush in the hospital garden, mentioned in a letter written to his brother Theo and Theo's wife Johanna a few days after his arrival:
I have two other [paintings] to send - purple irises and a lilac bush. Two subjects taken from the garden.[5]
