This topic has come up before but I haven't seen anyone with this exact problem. My oregano plant that for the last two years has been spicy and flavorful, has absolutely no flavor whatsoever the last few months. I believe its a "Greek" oregano but cant be sure now. It's been growing in a pot (a little over two years) and I live in So-Cal so it is fine through the winter. Also in the pot is a sweet marjoram plant. Has it reseeded bad seeds that have taken over? If so, what is the way to prevent that? Thanks!
