The camera is getting a good picture of the bright area in the background but that means that the plant is too dark.
One way to get the camera to show the detail in the plant is to aim the camera in the same place but get it to set the light meter for the plant. The area where the light meter reads (and where the camera will focus) is usually shown by the camera putting a rectangle on that area.
If you see that rectangle light up, it will be over the lighter background so touch your finger to the screen where the plant is located and the camera will switch to expose the plant correclty.That will make the background really bright but it will get the camera to expose the plant correctly.
