QuestionsHow to growSummer BeddingFlowersDried out Lobelia 0 Vote Up Vote Down Mary Holly asked 17 years ago I have dried out lobelia due to lack of watering while I was recently away. Would it regrow if I cut it back – similar to pansies at this time of year? I am saturating it with water at the moment as best I can. Its in pots.
