<strong>Plants</strong> <strong>with</strong> <strong>toxic</strong> <strong>alkaloids</strong>: Solanum tuberosum<br />
Some notorious non-edible nightshades include<br />
tobacco, petunias, jimson weed, mandrake, and<br />
deadly nightshade. The family also comprises well<br />
known food plants such as potatoes, tomatoes,<br />
green peppers, chili peppers, eggplants and<br />
tomatillos.. Genetic testing <strong>of</strong> proved a single<br />
origin for potatoes in the area <strong>of</strong> present-day<br />
southern Peru from a species in the Solanum<br />
brevicaule where they were domesticated 7,000–<br />
10,000 years ago.<br />
Wild potato contain sufficient saponins <strong>of</strong> the<br />
steroid type to warrant caution.<br />
Some potato varieties produce small green fruits that resemble<br />
green cherry tomatoes, each containing up to 300 true seeds.<br />
Potato fruit contains large amounts <strong>of</strong> the <strong>toxic</strong> alkaloid<br />
solanine and is therefore unsuitable for consumption. All new<br />
potato varieties are grown from seeds, also called "true seed" or<br />
"botanical seed" to distinguish it from seed tubers.
