We believe that an understanding of basic Botany and in particular, the way in which plants grow, is fundamental to your practice of landscape design. Here is a link to an online course which seeks to expand your knowledge of plant naming systems, plant structure and plant physiology: http://www.landscapetutor.net/course/view.php?id=28
A user name and password is not required, simply enter as a guest. We are in the early stages of developing that course but as a minimum, you need to complete the module on how plants are classified.
