About

Lobelia inflata, also known as Indian tobacco or puke weed, is a species of Lobelia native to eastern North America, from southeastern Canada (Nova Scotia to southeast Ontario) south through the eastern United States to Alabama and west to Kansas.

How to grow it

Propagation is usually accomplished by cuttings or seed. Seeds are sown in containers in mid spring or mid fall. The seeds take about 2 weeks to germinate.

Safety

Lobelia inflata has a long use as a medicinal plant as an entheogenic, emetic, and skin or respiratory aid. Native Americans used it for respiratory and muscle disorders, as a purgative, and as a ceremonial medicine. The leaves were chewed and smoked. The plant was used as a traditional medicinal plant by the Cherokee, Iroquois, Penobscot, and other indigenous peoples. The foliage was burned by the Cherokee as a natural insecticide, to smoke out gnats.

Although it may be used medicinally, consuming lobelia causes adverse effects, which may include sweating, nausea, vomiting, diarrhea, tremors, rapid heartbeat, mental confusion, convulsions, hypothermia, coma, or possibly death. The root is toxic and can be fatal if eaten.

Where it grows

Lobelia inflata is pollinated by small bees including sweat bees.
