We are happy to announce the return of our in-person outdoor Field Classes!


 Join Heather Luna for a fun, informative and hands-on experience in the field

to learn about the edible & medicinal plants of the Sierra Foothills 

​Field Classes are, you guessed it, held in out in the field at various locations throughout the Nevada County area. Class locations range from the cozy nest of our school Medicine Garden to various treasured trails and forests in the wild landscape of the Sierra foothills.

Field Classes Include:

  • Herb Walks
  • Plant Identification
  • Herbal Actions and Medicinal Uses
  • Fresh Plant Medicine Making in the field
  • Harvesting and processing techniques
  • Foraging Ethics
  • Plant Communication


These Field Classes are rich botanical adventures which strengthen our relationships to the plants and the use of herbs into our daily lives. Due to the variation of ecosystems and activities held at each field class throughout the season every stand-alone class is a unique experience that cannot reflect the entirety of outdoor adventures we will embark throughout the year. For the full experience of traveling through the seasons join us once a month. These are inspirational botanical play days for every level of herbalist. Spend the day immersed in botanical wisdom with Heather Luna. ​


All medicine making materials will be provided. You will be participating in hands-on medicine making in the field. Everyone will take home medicine we make during our Field Classes. 

  • ​​Classes will be held once a month starting in September
  • Learn plant identification and Materia medica
  • Hands-on medicine making in the field (all materials are provided)
  • Take home medicines made that day
  • You can register for each class individually or as a group program with a discount. More details to come.
