Here are some of the places I’ve traveled to in my career and for personal enjoyment that I recommend for any plant lover!
Missouri Botanical Gardens in Saint Louis is one of the best I’ve ever visited!
Alchemi Restaurant which has botanical inspired cocktails and mocktails with fresh ingredients from its own small indoor hydroponics system.
Blue Ridge Mountains in North Carolina which has beautiful views and divers plant life. Quite the area to explore.
Topiary Park in Columbus, Ohio merges plants and art in this tribute to the art piece A Sunday Afternoon on the Ile De La Grand Jatte.

The National Botanical Gardens in Washington DC across from the Capitol Building is a beautiful building with amazing educational aspects from other Smithsonian Museums and the US Department of Agriculture. The plants are beautiful! If you are ever in DC, its worth a look!
