Introduction to Xeriscape

Xeriscape is not only a concept, it should be a way of life in Colorado.

Gardening in a way that conserves water and enhances our lives seems like a no-brainer. But, breaking the paradigm of landscapes dominated by Kentucky bluegrass has been slow in coming. However, since the early '90s, we've been making progress and people have been implementing beautiful, low water consuming, low maintenance, wildlife attracting, jaw dropping beautiful gardens.

In this course I will de-mystify low water landscapes by explaining the seven principles of xeriscape and answering every question you can throw my way. Oh, and we'll look at some beautiful Denver area xeriscape gardens while we're at it!

In this lecture, botanical installation artist Lisa Waud describes her extraordinary project from idea to exhibition, discussing what about the installation was so magnetic to so many people across the worldåxploring her thoughts on beauty blight and nostalgia, as well as the themes of risk-taking, logistics and collaboration through the lens of the large-scale installation.
