More robust than Hidcote, and can tolerate heat, high humidity, and cold once established. Prefers full sun and requires very good drainage. Shear plants after blooming to encourage re-bloom. Do not prune after August. Do not prune in spring until new growth appears. Do not over water. Great companion for Geranium, Penstemon, Perovskia, and Coreopsis. Makes a wonderfully fragrant edging or low border.
