Near the end of the film as Rose bends down to exam the special tulip she's bred, the camera cuts to show her hand grasping the tulip. It's clearly someone else's hand - perhaps even a man's hand, with hairy arm and stubby fingers.
At the end. the movie when Rose and Tom are in the field, the trees behind them are bare of leaves, even though it is supposed to be spring.
When Rose and Tom are in the delivery van, shots of Rose show the sun coming in the passenger window and shots of Tom show the sun coming in the driver side of the van.
