Poppy field close to Prague?

Hello, im making a follow up/commentary YouTube video to “Heroin Holiday in Czech Republic” from Vice, released about ten years ago. I would like to make a part of a video, a take in/around a poppy field. Does anyone know about a field around, or close to Prague? I already have some footage from a Drop in, the needle exchange and with a ex-addicts, but would like to show the actual field as a background for the commentary parts. Anyone able to help?
