Question
I have Bidens frondosa growing out of a flowerpot that usually has standing water. (Identified based on the plants that grew nearby last year.) My question is, can Bidens seeds germinate underwater or do they require exposure to air?
Answer
Dear jfc, the short answer to your question is: I'm not certain. That written, many species of Bidens are wetland and aquatic plants that content with saturated soils (or standing water) on a regular basis. It would not be surprising that some species can germinate in standing water. Best wishes.
