Medicine Wheel Herb Garden Right outside of the retreat house, there is a peaceful medicinal herb garden. There are a variety of herbs growing here including: hibiscus, purple basil, stevia, oregano, thyme, white sage, patchouli, chamomile & more! You may help yourself to the garden during your stay! To visit the herb garden, you can sign up for a personal retreat, come out to an event, or join us for a volunteer day! Contribute to Amethyst
