"I love this place. Their customer service is absolutely outstanding. The staff has a great amount of knowledge. Anytime I have an issue with a plant, I pluck a leaf off of it put it in a ziplock bag, and then take it in. The staff easily assesses what the issues are and educates me on how to tackle the issue."

"Epically magical plant store! The turtles, the monstera, the euphorbia, the beauty! I also was able to snag a great deal on a hoya that I've wanted for a while. All in all, a great place to stop on our road trip 😸"
