Are there no works written in the language of flowers? - Henry David Thoreau

Our interactions with nature will become ever healthier, and support a productive co-evolution of humanity with the natural world, when they are based on a deeper understanding of nature. Can we truly see and experience nature as dynamic, interconnected and whole? That is an underlying question that will inform the week’s activities. The work will include careful sensory observation and just as careful attention to how we think about and judge the phenomena we are observing.

This course will be led by Craig Holdrege and Henrike Holdrege. Visit for more information and to register.

Themes of the work will include:

Earth, water, air and warmthPractical exercises and observations to understand these essential qualities that inform all life on earth.

Plant studyMetamorphosis; plant life forms—from annuals to perennials; domestication characteristics of food plants; assessing quality through our senses.
