The only Agastaches I've grown are the Hummingbird Blue and the white form of it. They're not that showy, but do smell nice and draw lots of butterflies and bees, and make a nice accent among other flowers. Those tend to be quite hardy and seed themselves here and there around the garden. I've tried a couple of others from seed with no luck, but I would love to try some of those other colors, that look showier in pics I've seen, and appear to have a looser, airier bloom form.
