I think it was Mary that posted a picture of her "Hosta Crewcut" (at least I hope it was ) Any hoo... I have a photo to make her feel better The earwigs have stripped every petal off my white & blue lobelia :-x At first I thought it was just the heat but all the other lobelia baskets are fine... Earwig eaten lobelia ( photo / image / picture from stratsmom's Garden ) Damn earwigs! ( photo / image / picture from stratsmom's Garden ) Is there anything those critters won't eat???
Honestly, it looks like the heat is getting to it. Mine looks like that once it starts getting hot. maybe this particular plant is more sensitive to the heat than the others or gets more direct sunshine. Lobelia doesn't do well in extreme heat. take a pair of scissors and trim off the brown part.
