– Highly attractive to pollinators—especially bees and butterflies

– Valuable nectar source during late summer to early fall

– Spring: dark foliage emerges early and develops structure

– Summer: flower buds begin to form

– Late summer to fall: vibrant bloom with strong contrast

– Winter: dried seed heads may remain for structure

– Focal point in rock gardens or modern landscape designs

– Containers and rooftop gardens

– Drought-tolerant borders and edging

– Mixed succulent plantings

– Pollinator-friendly spaces – attracts bees and butterflies

– Thick, fleshy, deep smoky purple to near-black leaves

– Oblong to spoon-shaped, arranged in tight clusters along upright stems

– Foliage color intensifies in full sun and heat

– Produces bright magenta-pink flower heads in dense, flat clusters

– Bloom period: late summer to early fall (August–October)

– Flowers provide strong contrast against the dark foliage

– Stems are upright and sturdy—resist flopping

– Plant in spring or fall for best establishment

– Space 18–22 inches apart to allow for full growth and air circulation

– Requires well-drained soil; thrives in sandy, gravelly, or loamy soils

– Avoid rich or poorly draining soils to prevent root rot

– Set crown at soil level; firm soil gently around roots and water lightly

– Cut stems to the base in early spring before new growth emerges

– Deadhead blooms in fall for tidiness or leave for winter texture

– Does not require midsummer pruning; naturally upright

– Drought tolerant once established

– Water regularly during first 2–3 weeks post-planting

– Thereafter, water only during prolonged dry periods

– Avoid standing water or soggy conditions

– Requires full sun (6+ hours/day) for deepest foliage coloration and sturdy growth

– Partial shade may lead to reduced color intensity and more open form

– Flowers may be harvested at peak bloom for fresh arrangements

– Dried flower heads can be collected for long-lasting floral decor

– Foliage is rarely harvested but adds value in arrangements when fresh

– Low fertilizer needs; thrives in nutrient-poor soils

– Apply a light compost or balanced slow-release fertilizer in early spring if necessary

– Avoid nitrogen-rich fertilizers that may cause lanky growth

– Pollinated by bees, butterflies, and other beneficial insects

– Primarily ornamental; propagated vegetatively to maintain traits

– Echinacea purpurea or Echinacea 'White Swan' – upright form and complementary bloom time

– Rudbeckia ‘Goldsturm’ – golden blooms contrast with dark foliage

– Pennisetum alopecuroides – soft grasses add texture and motion

– Perovskia atriplicifolia (Russian Sage) – drought-tolerant, airy floral balance

– Allium ‘Millenium’ – similar growing conditions with late summer blooms
