@juddchef I hear it grows easy from seed. You could always try buying seed packets. Cheaper that way and if they grow good you could get a ton of plants for very little money, although you'd have to wait a couple seasons for it to get to size.
I grow it as a native nectar source for local pollinators.
I was just looking and my seeds getting ready for fall planting. After that I was going through a book that recommends plants for the local Mediterranean climate and Agastache species was recommended. Rummaged around and found some foeeniculum "Lavender" and some rupestris "Sunset". I recall given them a try once, but stuff doesn't always turn out. I'm going to make a more concerted effort this time.
