Other names : Toothache Plant, Eyeball Plant, Peek-A-Boo Plant, Spot Plant, Prickelblume, Alphabet Plant, Jambu, Australian Cress, and Brazil Cress, Para cress, Akarkar, Pipulka, Akarkara, Hemmugalu, Pirazha, Acmella oleracea, Spilanthes acmella var. oleracea, Spilanthes fusca<br>It is an annual that grows to a height of 12 to 15 inches (30 to 38 centimeters) with a spread of 24 to 30 inches (61 to 76 centimeters). This member of the daisy family is a tender, fast-growing ornamental, culinary and medicinal plant native to Brazil. It is commonly known by the names toothache plant and paracress. The herb takes the latter name from Para, the Brazilian state where Acmella oleracea is used extensively for both culinary and medicinal uses. In its native habitat in the tropics of Brazil, the toothache plant is a perennial, but in cooler climates where it is too tender to survive the winters, it can be treated as an annual.
