they are beautiful but know that plant seeds, are toxic to children and pets and adults if chewed, I love that you can actually watch the flower open it moves and shakes and then opens before your eyes and smells so pretty, you will love it, good luck, will be posting more cause i have lots of seeds
yes they do come back every year, at least they have living in Amarillo, Tx and here in Nevada they get a long tap root, so they came back from roots even if winter kills the plant to ground
