Easy to grow from seed planted in garden beds in areas with long summers (I am in USDA Zone 9b). It does need a minimum of care. It will reseed, but has not been a pest for me. Blooms all summer long. I have seen it growing in Zone 4a with success, if started indoors early. Should be used more often.
