 Herb with creeping rhizom, 0.10-0.20m, native to Europe; leaves mostly 2, elliptic-lanceolate; flowers bell-shaped, white, highly fragrant, pendent on a one-sided raceme; fruit a red berry.
-"C. majalis is a native of Europe, where it largely avoids the Mediterranean and Atlantic margins. An eastern variety, C. majalis var. manschurica occurs in Japan and parts of eastern Asia. A limited native population of C. majalis var. montana occurs in Eastern USA . There is, however, some debate as to the native status of the American variety."

 The fragrant volatiles of Convallaria majalis flowers were enriched by dynamic and vacuum headspace sampling. The products of the vacuum process displayed a more typical odor, maybe due the higher content of farnesol (2-3%) and 2,3-dihydrofarnesol (2%). Main volatiles of the flowers (vacuum) were benzyl alcohol (27-44%) and geraniol (10-17%), together with (E)-ocimene (traces), citronellyl acetate (0.5-3%), (Z)-3-hexenyl acetate (1%), benzyl acetate (1%), phenylacetonitrile (2-4%), phenylacetaldoxime (1-2%), and cinnamic alcohol (3-7%). \\

 GC-MS analysis of vacuum headspace samples of the flower scent showed main components with floral-rosy-citrusy notes like citronellal, citronellol (9.6%), citronellyl acetate (1.1%), geranyl acetate (3.3%), nerol (1.3%), geraniol (8.4%), benzyl alcohol (35.2%), phenylethyl alcohol (0.78%), geranial + benzyl acetate (0.96%), neral (0.02%),  phenylacetonitrile (3.0%), farnesol (1.9%) and 2,3-dihydrofarnesol (0.88 %); green-grassy notes like (Z)-3-hexen-1-ol (10.6%), (Z)-3-hexenyl acetate (7.8%), (E)-2-hexenal (0.18%), and (Z)-3-hexenal (trace); fatty, waxy, aldehydic notes like octanal (0.15%), nonanal (0.1 %), and decanal (0.07%). \\
-Important trace components could be revealed by GC sniffing analysis, like (Z)-3-hexenal, green pea and galbanum-like notes like 2-isopropyl-3-methoxypyrazine and 2-isobutyl-3-methoxypyrazine, fruity-raspberry notes like β-ionone, and green-fatty and cucumber notes like (E,Z)-2,6-nonadienal and (E,Z)-2,6-nonadienol. \\
