A system for monitoring plants comprises an input unit, an output unit, and a processor that provides (201) image data (107) for a plurality of plants, each image data being associated with an individual plant. It associates (204) the image data (107) of each plant with corresponding plant characteristic data (109). It selects (206) a subset of the plants based on the plant characteristic data (109). It generates (207) a plurality of computer graphics objects corresponding to the selected plants. It applies (208) the image data (107) of each selected plant in form of a computer graphics texture to the corresponding computer graphics object. It determines (209) a position of each computer graphics object in a three-dimensional space of a computer graphics scene. It creates (210) a computer graphics rendering of the scene. It displays (211) the computer graphics rendering.
