Wildlife Attraction
|
- Attracts: Birds are drawn to the seed heads in fall and winter, while the tall foliage provides shelter for small wildlife.
- Wildlife Resistant: Deer and rabbits typically avoid this grass, making it a good choice for wildlife-prone areas.

Seasonality
|
- Foliage Season: Spring through fall, with winter interest from seed heads and dormant foliage.
- Flowering Season: Late summer to early fall (August to October).
- Hardiness Zones: USDA Zones 3-9
|
Ideal For
|
– Native and prairie-style landscapes
– Naturalistic and meadow plantings
– Erosion control on slopes
– Wildlife-friendly gardens (host plant for some butterflies)
– Structural accent in large beds and borders |
Leaf Description
|
- Color: Smoky blue-green leaves in spring and summer, transitioning to deep purple, red, and bronze tones in the fall.
- Form: Narrow, arching leaves that form a dense, upright clump.
- Winter Interest: The foliage and seed heads remain attractive throughout winter, adding structure and movement to the landscape.
|
Flower Description
|
- Color: Purplish-bronze flower heads appear on tall, upright stems.
- Form: The flowers emerge as feathery, three-pronged seed heads resembling a turkey's foot, adding texture and interest to the garden.
- Bloom Time: Late summer into fall, followed by ornamental seed heads that persist through winter.
- Fragrance: Not fragrant.
|
Planting Instructions
|
- Planting Time: Best planted in spring or early fall when the soil is warm and moist.
- Soil Requirements: Prefers well-drained soil and can thrive in a variety of soil types, including sandy or clay soils. Tolerates poor, dry soil once established.
- Planting Depth: Plant at the same depth as in the nursery pot, ensuring roots are well-covered with soil.
- Spacing: Space plants 24-36 inches apart to allow for mature growth and airflow.
|
Pruning & Maintenance
|
- Timing: Prune in late winter or early spring before new growth begins.
- Method: Cut back the dried foliage and seed heads to about 6 inches above ground level to encourage fresh, healthy growth in spring.
|
Water Needs
|
- Watering Frequency: Water regularly during the first growing season to establish roots. Once established, Holy Smoke is highly drought-tolerant and requires minimal watering.
- Soil Moisture: Prefers dry to moderately moist soil but is adaptable to different moisture levels as long as the soil is well-drained.
|
Light Needs
|
Full sun for best color and growth. Can tolerate partial shade, but may become leggy and less colorful in low-light conditions. |
Harvesting
|
– Primarily ornamental, not typically harvested for floral use due to coarse texture
– Can be harvested for dried floral arrangements – cut flowering stems when seed heads are fully formed but not yet shattering
– Harvest in late summer to early fall; hang stems upside down in a dry, well-ventilated area
– Leave seed heads standing through winter for seasonal interest and wildlife value
– In ecological restoration or meadow plantings, seeds may be collected for propagation, but this cultivar is usually propagated vegetatively to maintain its unique color traits |
Fertilizing
|
- Fertilization Time: Typically does not require fertilizer in average to poor soils, as it thrives in low-nutrient conditions.
- Fertilizer Type: If desired, apply a slow-release, balanced fertilizer in early spring to support vigorous growth. Avoid over-fertilizing, as this can cause the grass to become floppy.
|
Additional Care Tips
|
- Mulching: Mulch around the base in early spring to retain moisture, improve soil structure, and suppress weeds. Keep mulch away from the crown to prevent rot.
- Drought Tolerance: Once established, Holy Smoke is extremely drought-tolerant, making it perfect for xeriscaping or low-water landscapes.
- Pests and Diseases: Generally pest and disease-free. Ensure good air circulation to prevent fungal issues in overly humid or wet conditions.
|
Pollination
|
Wind-pollinated; produces seeds that may self-sow if left on the plant. Seed heads also attract birds in fall and winter. |
