The Mountain Thyme Herb Society, a non-profit 501(3)c, was started in 2016 as a way for people who grow and like herbs to connect with each other and learn. In 2017 Durango Botanical Society gave MTHS a piece of land in the Botanic Gardens to establish an herb garden.
The Sundial garden was finished in 2019 and has 12 different kinds of Thyme, representing the hours of the day. The sundial sculpture is the work of Brian Saren, who has also sculpted art panels around the Arboreta.
Included are Rose Petal Thyme, English Thyme, Lavender Thyme and Lemon Thyme among others. A ring of Chamomile surrounds the sundial. November 2020 will see the excavation for the herb gardens that will surround the sundial, a culinary herb garden, medicinal herb garden, pollinator garden and sensory herb garden.
