I bought my original seeds from Diane's Seeds in 2012. My experience is similar to Jen's. It self sows gently, and I typically share extra seedlings with friends. I think of it as short-lived, but it might be our conditions. Our plants are mainly in full sun or morning sun and gravelly soil. I don't give them supplemental water. Sometimes the plants wilt on the hottest summer days (when other Agastaches in the yard aren't wilting), but there may be more clay in the soils where the other Agastaches are growing. I love this one for the way the foliage lights up the garden and the way the bees adore the flowers
