I found some info on metel
D. metel is used in Chinese medicine as an antispasmodic crude drug and the dry flowers are used as an anaesthetic. D. metel var. muricata (obtained from Nagoya, Japan) was double recessive with respect to the genes concerning colour and form of the corolla in experiments involving 4 varieties: var. metel (white, simple corolla), var. rubra (purple, simple), var. fastuosa (purple, double or triple) and var. muricata (white, double). It was suggested that the results supported the proposal that these variants should be considered as varieties or forms of a single species, D. metel. Scopolamine was always dominant over hyoscyamine in seeds, flowers and leaves of the 4 varieties. Scopolamine content (dry weight basis) of seeds, flowers and leaves ranged from 0.294 (var. rubra) to 0.631% (var. fastuosa), 0.19 (var. metel) to 0.698% (var. rubra), and 0.042 (var. rubra) to 0.255% (var. metel), respectively. It was concluded that all 4 varieties can be utilized as sources of scopolamine.
