Origin

• Native Range: American Bistort is native to North America, found in moist, open slopes in montane, subalpine, and alpine areas from western Canada to New Mexico.
• Habitat: Prefers high-altitude regions with well-drained, moist soils. It thrives in areas with consistent moisture, such as near streams and meadows.
• Alpine Bistort (Polygonum viviparum): Found farther north, adapting to colder climates and shorter growing seasons.

How to Grow

Growing Conditions:

1. Climate: American Bistort is suited to cooler climates with adequate moisture. It performs well in USDA hardiness zones 3–8.
2. Soil: Prefers moist, well-drained soils that are slightly acidic. Add organic matter to enhance soil quality.
3. Sunlight: Thrives in full sun to partial shade.

Propagation:

1. Seeds:
   • Collect seeds in fall when the achenes are mature.
   • Stratify seeds in the refrigerator for 6–8 weeks to mimic winter conditions before planting.
   • Sow seeds in early spring in moist soil.
2. Root Division:
   • Divide thick rootstocks in early spring or fall.
   • Plant divisions 2–3 inches deep, ensuring the crown is above soil level.

Care:

• Water regularly to keep soil moist but not waterlogged.
• Mulch with organic matter to retain moisture and regulate temperature.
• Remove competing weeds to allow the plant to establish.

Harvesting:

• Harvest leaves and shoots in spring.
• Roots can be dug up in early spring or late fall, ensuring sustainable harvesting by leaving some rootstock intact.

Companion Plants:

• Grows well alongside other moisture-loving plants such as lupines, columbines, and meadow rue.
