I am still a little confused about the annual plants verses their seeds. I understand that annual plant bloom and live one growing season. However, some of the seeds from those annuals can survive in climates even though the plants cannot. This is not the case with all annuals. Is there any indicators to look for to help distinguish which annuals are self seeders in my zone? I know there was a list of self seeding annuals on a web site but is that a complete list?
