​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.

How to prepare for class

Please come prepared to work with the plants in their environments. While we live in temperature controlled rooms plants do not. Learning about plants means that we must adjust ourselves to the climates and habitats of Nature. Spending time in nature is a vital piece of being an herbalist. Spending time in Nature should not be limited to fair weather and sunny days. This means being prepared to meet your personal comfort needs as well as the needs of an outdoor learning/classroom environment so that everyone can enjoy the time together (plants included).

Please come to all outdoor field classes with the following items:

  • Full water bottle
  • A sack lunch and trail snacks for the day
  • Good walking shoes (weather appropriate such as waterproof hiking boots and wool socks)
  • Notebook and pen/pencils (cameras are also welcome)
  • A personal blanket or towel to sit on outside
  • Plastic grocery bags (we pick up trash along the way)
  • Weather appropriate layers of clothing:
    • Long pants (with wooly unders/leggings if cold), short sleeves shirt or tank top with long sleeve shirt on top. Plus a hoodie or wool sweater. **Remember you can always shed layers, but you can’t magically make new layers appear while out in the field.
    • Sunhat and light weight loose long sleeves and pants to prevent bug bites, bramble scratches and sunburn on sunny days
    • Rain slicker with waterproof hood and water proof gear with warm wool under layers on rainy days
    • A backpack to store gear and extra layers of clothing 



Optional tools and materials

We will use these tools for medicine making in the field. If you choose to bring your own tools and equipment please label each with your name. 

  • Pocket knife
  • Garden snips/clippers/hand pruners
  • Small shovel/trowel/ hori hori/ or other digging tool
  • Folding garden saw
  • Baskets or collecting bags (canvas or paper)
