It is Missouri's oldest town founded in 1735.
"This is the first permanent settlement in Missouri well before Missouri was a state," explains Sandra Cabot, the Director of Tourism for Ste. Genevieve.
A place that is home to the first brick building west of the Mississippi and several other buildings that are becoming more and more rare.
"We have about 30 buildings remaining in Ste Genevieve that are the French vertical log construction," Cabot points out.
Many of which are open to the public, but one weekend out of the year the focus in Ste Genevieve is flowers thanks to a self-guided walking tour that begins at the Welcome Center and continues through 24 public and private gardens including Joan Troeh's garden.
It's a plot of land that was all grass and weeds when she moved in back in 1985.
"With a shovel and with my hands I got rid of all of the weeds and all of the grass and sold my lawnmower to one of my brothers and did all of this," she explains.
There isn't a square inch of grass because when this master gardener retired six years ago she really dug in and well, lost track of how many varieties of plants and flowers she now has.
"I couldn't begin to tell you."
It is absolutely stunning, even if it's become a bit of an obsession.
Of course other stops along the way are also impressive and at the Felix Valley State Historic site visitors can get an idea of what was grown when these buildings were rather new.
"The things they would have had in their garden because they're French is also going to include medicinals, herbals, things just because they liked them but most of the plants in their garden are things you could use for a variety of things," Donna Rausch, the Admistrator of Felix Valley State Historic Site says.
There's False Indigo and Santalina.
"If you smell of it, it smells like mentholatum so it was used kind of like that."
So take a stroll back in time this weekend and experience the beauty and history of Ste. Genevieve, America's Original French
