Saint Fleurant's paintings often depict maternal scenes of females, children, trees, wildlife, and Haitian Vodou Loas.

Her folk painting style is often colorful and vibrant and expresses a distinct female perspective on the Saint Soleil movement and Haitian Vodou art.

Along with Prospere Pierre-Louis, Dieuseul Paul, Denis Smith, and Levoy Exil, she formed the renowned Cinq Soleil (Five Suns) art movement.

In 1974, she joined Poisson Soleil, initiated by Tiga and Maude Guerdes Robart, in an inaugural exhibition at the Museum of Haitian Art.

[2] Her work has been exhibited in Asia, Europe, and the United States[3] and has recently been part of fundraising, relief, and awareness efforts following the 2010 Haiti earthquake[citation needed].
