Tobacco seeds

Tobacco (bot. Nicotiana tabacum) is a perennial herbaceous plant. It is found only in cultivation. Its leaves are commercially grown in many countries to be processed into tobacco. It grows to heights between 1 to 2 metres. Research is ongoing into its ancestry among wild Nicotiana species, but it is believed to be a hybrid of Nicotiana sylvestris, Nicotiana tomentosiformis, and maybe Nicotiana otophora. Ethnobotany: Tobacco was widely used in northern North America.

Peyote seeds (Lophophora williamsii) cactus

Peyote is a small, spineless cactus whose native region extends from Texas and New Mexico through central Mexico. All Lophophora species are slow growing, often taking up to 30 years to reach flowering age in the wild. Human cultivated specimens grow considerably faster, usually taking from six to ten years to go from seedling to flowering adult. Peyote is considered to be in danger of extinction in the wild. Ethnobotany: From earliest recorded time, peyote has been used by natives in northern Mexico and the southwestern United States as a part of traditional religious rites.
