Common Name(s) Potato
Latin Name Solanum Tuberosum
Description The leaves grow along the stem with a single leaflet, often the largest at the tip and two lateral rows  of broad oval leaflets interspersed with varying numbers of smaller leaves. The flowers are white, pale purple or tinged with red depending on the variety. After flowering many varieties produce fruits similar to small green tomatoes. The tubers are produced on white underground stems.
Hazards All parts of the plant growing above the ground contain alkaloids, after prolonged exposure to light potatoes themselves turn green and can be harmful if eaten.
Effects The tomato like fruits which appear after flowering can be attractive to children and if eaten can cause vomiting and diarrhoea. Potatoes that have sprouted and turned green in colour are unsafe to eat, even if peeled and cooked can cause varying symptoms. Mild cases are usually digestive disturbances, more severe cases vomiting, diarrhoea, drowsiness, hallucinations and unconsciousness.  
Flowering Period Late spring.
Location Gardens, allotments etc.
