Popular in 16th century England, this unusual beauty is making a comeback in ornamental and cut-flower gardens for good reason—it's gorgeous in arrangements and lasts a long time. In the garden, it pairs nicely with bronze and deep-purple or red foliage. The plant is tough, thriving in lean and poor soils, as well as drought conditions and heat. Watch the bees and hummingbirds come calling for its sweet nectar.
