PHARMACAL PLANTS AND THEIR CULTURE. 
28. Stramonium. — Grows anywhere. Common in waste places. 
Culture can only be made profitable when the entire herb is used, 
excepting, perhaps, the coarse main stems. May be grown with 
Hyoscyamus (henbane) and belladonna. Cultivated in England and 
other European countries. 
29. Valerian. — Thrives exceedingly well in fairly moist, somewhat 
sandy soil mixed with clay. Can be grown in association with stra- 
monium, veratrums, and henbane. Easily cultivated. 
30. Veratrum. — The veratrums are marsh plants and could no 
doubt be introduced in some of the California marsh lands.
