"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!"

"Every time I've gone into this place has been a lovely time. Their plant selection is terrific, with beautiful sculptures and even turtles hanging out! Took a class with Evan today and made bookmarks, I plan on coming back to take more classes."
