Sea Lavender Duration

After searching for what really has been several years, someone on the internet suggested your catalogue. And I found sea lavender, I was so excited! Then to find out I could get it at a store in town...yay! However, in your catalogue you claim that it is a perennial (which I had been told it was all along). On the package that I purchased it says annual... Could you tell me which is correct?

The correct duration is perennial. Sea lavender (Limonium latifolium) is hardy in zones 4-9. It is native to Rumania, Bulgaria and southern Russia.
