I am movng from zone 9 to a place on the border between zones 7 and 8 (northern Alabama). The situation is such that I may be able to be there only from May to November each year. What annuals could I plant in early November, to be up when I come back? Since a lot of annuals self-seed, there must be some I could do this way. Someone will be there at the house, but she is not a gardener nor is she able to do much physically. Thanks in advance.
