The main source for this provenance is Alec Wildenstein's catalogue raisonné, cat. no. 1340 [Alec Wildenstein. “Odilon Redon: Catalogue raisonné de l'oeuvre peint et dessiné.” vol. III, “Fleurs et paysages.” Paris: Wildenstein Institute, 1996]
 According to two labels on the back (see above) the painting belonged to Joseph Hessel by 1920. Jos. Hessel was a Belgian collector and dealer of French Modern Art in Paris.
 According to another label on the verso, the pastel was was included in an exhibition at the Galerie Druet, Paris, in June 1923 [Exposition d'oeuvres de Odilon Redon (1840–1916): peintures, pastels, aquarelles, dessins, lithographies, eaux-fortes, art décoratif" Galerie E. Druet, Paris, June 11-30, 1923, lot. no. 86] It is not clear, if the painting was owned by the gallery or on loan.
 The stock book of the Dutch art dealer E.J. van Wisslingh & Co. records that Dutch art dealer Nico Eisenloeffels owned Exotic Flowers until 1951 [Van Wisselingh Archive, stock number 7196, Rijksbureau voor Kunsthistorische Dokumentatie, The Hague, The Netherlands]. Consequently the pastel was still in Eisenloeffels possession when Van Wisselingh included it in a Montreal exhibition in 1950 [“French Paintings of the XIXth and XXth Centuries.” (Coll. of Mr. P. Eilers of E.J. Wisselingh & Co., Amsterdam), Watsons Art Galleries, Montreal, cat. no. 19].
