Lavandula × intermedia Emeric ex Loisel., Fl. gall. Ed. 2, 2: 19 (1828).
Sold as “lavender flowers” in the potpourri trade, these are actually from lavandin, a hybrid of true lavender (L. angustifolia Mill.). Corollas generally are shriveled, but the lavender-colored calyces (in the native state) are 5-6 mm long x 1.5-2 mm wide. Sometimes, whole inflorescences, about 15-20 cm long, along with the brown bracts and bracteoles, are included in potpourri.
Lavandula × intermedia is native to France but widely cultivated.
