I was given some money plany seeds back in April.. put them in a planter spread pretty heavy since about 10% of what I plant actually come up. I realize they are biannual so I wasn't expecting too much. I ended up with a planter full of approx. 3-4" high kind of a clovery looking weed. I read about purple flowers of which I had none. It is now starting to die off. Am I to just let it do it's thing and hope for the best next year? Something dosn't seem quite right but I have the blackest thumb around so please advise.
