Pruning: Cut back hard in late winter or early spring (to within several inches of the ground) to promote dense growth and heavy blooming, as it blooms on new wood.
Maintenance: Requires excellent soil drainage to survive wet winters; avoid planting in waterlogged or heavy clay soil. It is tolerant of urban pollution and salt.
Fertilizing: Thrives in lean soils and rarely needs heavy feeding; a light, slow-release fertilizer in early spring is sufficient.
Habitat: An excellent choice for mass planting in borders, rock gardens, or xeriscaping due to its drought tolerance.
Wildlife: The plant is a magnet for a wide variety of pollinators, including diverse bee genera.
Other: Was a top performer in Chicago Botanic Garden trials, noted for its uniform size and prolific, long-lasting bloom.
