They should be perennial for you. Perhaps the label was designed for a range of markets; it would perhaps not be perennial in zone 6 - I think that it is behaving as a perennial here in zone 7, I see a lot of it lately.

I have grown agapanthus for years. In my zone, I must over-winter it in the garage, although we wheel them (four altogether) out on fine days. In zone 9, they should live forever. You will love them more than you can imagine.

We live on the Mississippi Gulf Coast and agapanthus are definitely a perennial here. They come back bigger and fuller each year. Beautiful flowers.

deinately perrinial here in jacksonville. Mine got bigger then looked horrible then bloomed beautifully. Not exactly what I wanted so they are going to my sisters house tomarrow ut very pretty while in bloom...
