Wildlife Attraction
|
– Highly attractive to butterflies, bees, and hummingbirds
– Considered a pollinator magnet and excellent for wildlife gardens
– Deer resistant and rarely browsed |
Self-pollinating
|
|
Seasonality
|
– Deciduous shrub – dies back to the ground in colder climates
– Blooms from July through September, with potential for reblooming if deadheaded
– Foliage returns in late spring |
Ideal For
|
– Pollinator gardens and butterfly habitats
– Borders, foundations, and mixed shrub beds
– Xeriscaping and drought-tolerant plantings
– Cut flower gardens and specimen shrub use |
Leaf Description
|
– Medium to dark green, lance-shaped leaves with a fine serrated edge
– Silvery or whitish underside gives the foliage a soft sheen
– Leaves are slightly fuzzy and aromatic when crushed |
Flower Description
|
– Produces long cascading panicles up to 12 inches in length
– Rich deep purple flowers with small orange-yellow centers
– Sweetly fragrant, especially noticeable in warm weather
– Flowers continuously from mid-summer to early fall |
Planting Instructions
|
– Plant in spring or early fall in a location with excellent drainage
– Dig a hole twice as wide and the same depth as the root ball
– Loosen roots before placing the plant in the hole; backfill with amended soil if needed
– Water deeply after planting and apply mulch to retain moisture and suppress weeds
– Space 5–6 feet apart to accommodate mature spread and allow air circulation |
Pruning & Maintenance
|
– Prune back hard in early spring to 12–18 inches to encourage dense new growth
– Deadhead spent blooms throughout the season to prolong flowering
– Remove weak or dead stems as needed |
Water Needs
|
– Moderate water needs when establishing – water deeply 1–2 times per week
– Once established, drought tolerant; prefers slightly dry conditions
– Avoid overly wet or poorly drained soils |
Light Needs
|
– Requires full sun (minimum 6 hours of direct sunlight daily)
– Less flowering and leggier growth in partial shade |
Harvesting
|
– Not grown for cut flowers or edible use; flowers can be cut for fresh arrangements
– Trim panicles when just opening for best vase life
– No parts are commonly harvested for food, oil, or ornamental seed |
Fertilizing
|
– Apply a balanced slow-release fertilizer (e.g., 10-10-10) in early spring
– Avoid over-fertilization, which can lead to leggy growth with fewer blooms
– Supplement with compost or organic mulch to enrich the soil |
Pollination
|
– Self-pollinating and seed sterile, meaning it will not produce viable seeds
– Attracts pollinators like bees, butterflies, and hummingbirds, aiding nearby plant pollination |
Companion Plants
|
– Salvia nemorosa – complements the spiky bloom form and attracts pollinators
– Echinacea purpurea – shares similar bloom time and drought tolerance
– Agastache – similar growing needs, vibrant color contrast
– Sedum – offers texture contrast and thrives in dry soils
– Perovskia atriplicifolia (Russian Sage) – echoes the airy form and adds soft silver hues |
