Pruning: Cut back old stems to the ground in late winter or early spring before new growth appears. Pinching new growth in early summer can encourage a bushier habit.
Fertilizing: Do not fertilize heavily; growing in poor to average soil helps maintain strong stems and intense foliage color.
Maintenance: Very low-maintenance, thriving in conditions like heat, drought, and urban pollution.
Habitat: Excellent for borders, rock gardens, mass plantings, or as a “thriller” plant in containers.
Other: Part of the “Rock ‘N Grow®” collection and a 2021 National Garden Bureau Green Thumb Award winner.
