Water lobelia
Lobelia dortmanna
Water lobelia is an aquatic perennial that grows submerged in shallow, cool, oligotrophic lakes and ponds with clean, acidic water. It requires very specific water quality conditions — low nutrients and high clarity — making it challenging to cultivate outside its natural habitat. Best suited for naturalistic pond plantings or bog garden environments that closely mimic its native soft-water ecosystem.
