"Love the pics. Will check out Bonsai class soon."

- Wendy Conn, January 2026

"Friendly employees, well stocked with all manner of plants, trees, and decor. I love all of the garden centers in FoCo, but Bath is definitely my favorite."

"Have just about everything you need for your yard."

- Bud Bussard, April 2024

"I brought my girls here to have a homeschool lesson about botany for their science study! We had one of their employees, Evan, walk us around the center and take us into the greenhouses. I felt like he went above and beyond to help my girls with what they need to know and it was great! My kids had a great time and he knew what he was talking about. Thanks again Evan!"
