In two of his chansons Chardon represented Marguerite de Bourbon, the wife (from 1232) of Theobald I of Navarre, in acrostics.
All Chardon's French poems have the form ABABX: the chansons are decasyllabic, the jeux partis octosyllabic.
A fifth chanson, no longer ascribed to Chardon, Li departirs de la douce contree, is notable for the simplicity of its melody compared to the "floridity" of that of Rose ne lis.
While Chardo's portion of the exchange, N'Ugo, cauzetz, avans que respondatz, survives, Uc's part does not.
Oskar Schultz-Gora (1884) first proposed to identify the troubadour with the trouvère, an identification accepted by Hermann Suchier in his edition (1907), followed by G. Huet (1908), Adolphe Guesnon (1909) and István Frank (1966).
