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.

The flowers attract long-tongued bees primarily, including Little Carpenter bees, Miner bees, Mason bees, and Leaf-Cutting bees. Small butterflies and skippers also visit the flowers occasionally, which are probably less effective at pollination. All of these insects seek nectar. The leaves and stems contain a watery white latex that is toxic, therefore most mammalian herbivores are less likely to eat this plant than others. However, deer appear to be somewhat immune to the effects of the toxins in lobelias. The seeds are too small to be of any interest to birds.
With its smaller pale flowers, Pale-Spiked Lobelia is less showy than some of its better known relatives, such as Lobelia cardinalis (Cardinal Flower) and Lobelia siphilitica (Great Blue Lobelia), but has better resistance to dry conditions once it becomes established. The flowers of these species all share a similar structure, but vary in their size and color.
