Baptisia 'Purple Smoke'

Common Name: Hybrid False Indigo

Baptisia ‘Purple Smoke’ is a striking and long-lived false indigo (Baptisia) hybrid prized for its smoky violet flower spikes and architectural presence in the late-spring garden. A chance seedling discovered at the North Carolina Botanical Garden, it combines the attractive gray-green foliage and charcoal stems of its parents with abundant, pea-like blooms held well above the foliage. Key features Width / spread: 3–4 ft at maturity (sometimes up to ~4–5 ft) Height: 4–5 ft at maturity, flower stems included Flower color: Smoky violet-lavender with dusky tones and charcoal stems Bloom time: Mid to late spring Foliage: Gray-green, finely textured deciduous clump Form: Upright, mounded clump with tall flower stalks Life cycle: Herbaceous perennial (dies back in winter) Growing conditions Sun: Full sun (best flowering performance) Soil: Average to well-drained soil; tolerates poorer soils once established Water: Moderate; drought tolerant once established Hardiness: USDA Zones 3–9 Landscape use Specimen plantings Back of perennial borders Prairie or meadow gardens Mixed perennial beds Cut flower and wildlife gardens Notes A standout Baptisia for gardens where height and vertical interest are desired without staking.
