- Winter interest
|
Leaf Description
|
- Color: Blue-green foliage in spring and summer, transitioning to shades of yellow and tan in the fall.
- Form: Narrow, arching blades that form a tall, dense clump with a graceful, upright habit.
- Winter Interest: The seed heads and dried foliage remain attractive through winter, adding texture and structure to the landscape.
|
Flower Description
|
- Color: Light, airy seed heads with pinkish-brown tones.
- Form: Large, airy panicles that rise above the foliage, creating a cloud-like appearance.
- Bloom Time: Late summer through early fall.
- Fragrance: Not fragrant.
|
Planting Instructions
|
- Planting Time: Plant in spring or fall for best establishment, though container-grown plants can be planted year-round with proper care.
- Soil Requirements: Prefers well-drained soil but is highly adaptable to a wide range of soil types, including sandy, loamy, and clay soils. Tolerates wet conditions but thrives in dry to moderately moist soil.
- Planting Depth: Plant at the same depth as in the nursery pot, ensuring the crown is level with the soil surface.
- Spacing: Space plants 3-4 feet apart for proper airflow and mature growth.
|
Pruning & Maintenance
|
- Timing: Prune in late winter or early spring before new growth appears.
- Method: Cut back the dried foliage and seed heads to about 6 inches above ground level to encourage fresh growth. Leaving the seed heads intact during winter provides both visual interest and food for birds.
|
Water Needs
|
- Watering Frequency: Water regularly during the first growing season to establish roots. Once established, Old Faithful® is drought-tolerant and only needs occasional watering during prolonged dry periods.
- Soil Moisture: Prefers moderately moist soil but can tolerate both wet and dry conditions, making it ideal for rain gardens or areas prone to occasional drought.
|
Light Needs
|
Full sun for optimal growth and flowering. It can tolerate light shade, but full sun encourages the best color and growth habit. |
Harvesting
|
When to Harvest Seeds:
- Wait until the seed heads turn brown and dry on the plant (typically late fall)
- Seeds should easily separate when rubbed between your fingers
How to Harvest:
Cut the seed heads using garden shears once fully mature and dry.
Place them in a paper bag and allow them to air dry further for 1–2 weeks in a well-ventilated area.
Shake or rub the seed heads to release seeds.
Store seeds in a cool, dry, and dark location in a labeled envelope or airtight container.
- Uses for Harvested Seeds:
- Sowing for propagation
- Leaving them in the garden for winter bird forage
- Decorative use in dried floral arrangements
|
Fertilizing
|
- Fertilization Time: Typically does not require fertilization in average to poor soils.
- Fertilizer Type: If necessary, apply a light, balanced, slow-release fertilizer in early spring to encourage healthy growth.
|
Additional Care Tips
|
- Mulching: Apply a thin layer of mulch around the base of the plant to retain moisture and suppress weeds, but avoid heavy mulching to prevent crown rot.
- Drought Tolerance: Once established, Old Faithful® is highly drought-tolerant, thriving in both dry and wet conditions. It is ideal for xeriscaping, rain gardens, or low-maintenance landscapes.
- Pests and Diseases: Generally pest-free and disease-resistant, though it may occasionally experience rust or leaf spot in overly wet conditions. Ensure good air circulation to prevent these issues.
|
Pollination
|
Wind-pollinated, with the seeds often dispersed by wind. The airy seed heads contribute to the plant’s wildlife value, providing food for birds in the fall and winter. |
