It is an important basis to construct virtual plant model according with the law of botany before simulating the development process of plant dynamically. To improve the function of Open-L system and overcome the shortcoming and inconvenience in application, a modeling framework of information communication between the plant and its growth environment was founded. It introduced a recursive method to construct a virtual plant model. An example of modeling plant through new method was given, which showed that the modeling method was effective in simulating the plant growth under the interaction with the environment. 
