For making génépi liqueur, several species of
Artemisia (the genus of the wormwoods) are particularly valued, including
A. genipi (black génépi) and
A. umbelliformis (white génépi) - either of which being sometimes referred to as
A. rupestris. The botanical identification of the plants traditionally collected for use in making génépi liqueur is complicated by scientific reclassification work in the genus
Artemisia, spurred by recent trends in
molecular assay and
cladistics , that has resulted in the decline in use (among academics) of common names used in traditional literature. It is likely that a wide range of wormwoods native to the mountainous areas of Spain, France, Switzerland and Italy have been used to make the liqueur, with personal taste, tradition and availability shaping the selection. According to Stephen Gould, "Any liquor/liqueur made with any member of the artemisia family, except artemisia ab. (Grand wormwood) would be considered a Genepi ..." Other species known to have been used at one time or another in producing génépi are
A. glacialis,
A. pontica and
A. borealis. Flowers of "Alsem der Alpen", the botanically related
Achillea erba-rotta subsp. moschata known in English as musk milfoil, are sometimes added or used to substitute entirely for one or more of the génépi species. Collectively, these various Alpine plants that blossom at high altitudes during July and August are known in German as "Edelraute". == Génépi at home ==
