This hyssop created a big buzz in the garden world, with its brilliant chartreuse foliage and compact form - growing to only 20” tall x 15” wide. In Summer it bears 4” purple flower spikes much loved by hummers, butterflies and bees. The foliage is nicely serrated and heavily mint-scented. Loves heat and makes nice cut flowers. Rare among the Agastaches, it does not like intense sunlight, preferring filtered light or part shade in hot sun areas. Reseeds for freebies!
