Sorry, ignore the above reply by me; I meant it for the Agastache 'Blue Fortune' and put it on the wrong page. :-o The info for the Love in a mist is that it is an annual, so no zones are listed. You have to collect seeds each year and sow them in the spring. I always miss some seeds each year that winter over and come up by themselves in spring. The scientific name for this plant is Nigella damascena 'Oxford Blue' if you wish to look up the full care instructions on Dave's Garden.com under PlantFiles.
