Class Overview:
Discover the fascinating world of moss and the important role it plays in natural ecosystems in this hands-on class. Join Marc Eaton, owner of Roots, Shoots & Leaves mobile retail shop to create your own miniature enclosed moss landscape in a glass jar while learning about the unique adaptations that allow mosses to thrive in forests and other habitats. Explore how these tiny plants help retain moisture, stabilize soil and contribute to healthy ecosystems, then apply those principles to create a living display for your home.
Whether you're a longtime plant enthusiast or simply looking for a creative way to connect with nature, you'll leave with a greater appreciation for these often-overlooked plants — and a beautiful moss ecosystem of your own to enjoy.

- The basic biology and life cycle of mosses
- How moss contributes to healthy ecosystems in nature
- Best way to design and assemble a miniature moss ecosystem in a glass jar
- Which materials and moss varieties work best for jar gardens
- How to care for and maintain your finished moss display — once constructed, an enclosed mossarium requires less hands-on maintenance.

We recommend that you enter the Arboretum via the back gate on 82nd St, not the main entrance on Hwy 5. This is the most direct route to access the Farm at the Arb, and avoids potential delays when driving through the Arboretum.
Directions: 3210 W 82nd St, Chanhassen, MN 55317
If you do wish to enter through the main Arboretum gate on Hwy 5, you can take 3-Mile Drive through the Arboretum and turn right on Peter Moe Drive to get to the Bee Center (this route may take an additional 15-20 minutes, so please plan accordingly).
Main Entry instructions:
You will receive a bar-code ticket for entry to the Arboretum in your email purchase confirmation. Your ticket is valid for entry on the day of your class. Present your ticket to the gate attendant as you enter the Arboretum. You may stay at the Arboretum after class as long as you want during our operating hours.
