Welcome to The Plant Firm
The Plant Firm was created during the lockdown of 2020 as a fun project to give me something to do. It quickly became a much larger endeavor and one that I knew needed more attention to be done right. I was tired of paying an arm and a leg for plants at the big box store and saw an opportunity to save people time and money while also delivering straight to their door. So, here we are in 2023. Officially up and running with an amazing team, more plants, and a desire to provide you with better plants at better prices!
