Bear's breeches usually wows us with it jagged leaves, but it now also boasts striking white margins and mottling. In late summer, the leaves of 'Tasmanian Angel' are joined by 3-foot-tall, pink-and-cream flower stalks. As the leaves age, the variegation is said to diminish, but it still makes a great multiseason container specimen or a fantastic bedding plant.
