Hyacinth flowers are seen in the bedroom during mid autumn in Great Britain in the early 1920s. These plants bloom in the springtime.
Collared Dove ( Streptopelia decaocto)
About an hour into the film a collared dove is shown at the window. This type of dove was present in the UK until the 1950's. It spread rapidly from the Middle East across Europe in the 20th century.
The film is supposed to be set during the early 1920's but when Lady Chatterley is sent away by her husband, a brief scene is shown of a steam locomotive travelling towards the camera. The Standard Class 4-6-0 is number 75043 - this number was not allocated until nationalisation of the four big railway companies and the formation of British Railways in 1947.
