Heliotropium arborescens L. - syn.Heliotropium peruvianum L. - Boraginaceae
(garden) heliotrope, cherry pie, Heliotrop, Vanilleblume, (Strauchige) Sonnenwende

Fragrant evergeen shrub, native to the peruvian Andes. Commonly cultivated as annual herb, sometimes with variegated color of the leaves (violet-green or golden) or flowers (white).

„Flavors of heliotrope flowers were analyzed by Solid Phase Microextraction Method (SPME) equipped with GC-MS. The major volatiles identified were benzaldehyde, benzyl acetate and p-anisaldehyde.“

„The majority of the volatile compounds emanating from the flowers were terpenes (camphene, p-cymene, δ-3-carene, α-humulene, δ-1-limonene, linalool, (E)-β-ocimene, α-pinene, and β-thujone), benzenoids of which benzaldehyde was the most abundant, aldehydes (decanal, heptanal, nonanal and octanal), and hydrocarbons decane, heneicosane, heptadecane, hexadecane, nonadecane, nonane, octadecane, tetradecane, tridecane and undecane) along with a cross-section of other compounds.“
