Editor's Note

Some resources list all parts of Lobelia species and cultivars as poisonous if large quantities are ingested.

The toxic principals include the alkaloids lobelamine, lobeline, and others, plus a volatile oil.

Symptoms include nausea, vomiting, diarrhea, salivation, exhaustion and weakness, dilation of pupils, convulsions, and coma.

We tend to err on the side of caution in PlantFiles, and the danger notation in the details above is to warn gardeners, parents and pet owners to look further for more information before eating.
