Description

Downy lobelia is a perennial herb that grows up to 2.5 ft (1 m) tall. Leaves are simple with a toothed margin. The flowers are blue to violet, five-lobed, and bloom from July to October.[5]

Lobelia puberula is similar to two other Lobelia species in to the Eastern United States, Lobelia inflata (Indian tobacco) and Lobelia siphilitica (great lobelia); all display the characteristic "lip" petal near the opening of the flower and the "milky" liquid the plant excretes.[6]

gollark: Are you suggesting that viewbombers also AR or something?
gollark: I generally miss eggs by just clicking past to the next biome then suddenly noticing then going back.
gollark: I generally try to fully read descriptions before clicking them, which may be why I usually can't get anything.
