Care Guide
Planting
Plant purple black-snakeroot in partial shade, where it will thrive in the dappled light of Bay Area gardens. This native perennial prefers well-draining soil and can handle the serpentine soils it naturally grows in throughout coastal California. Space plants about 2 feet apart to accommodate their mature height. Plant in fall or early spring to give the roots time to establish before summer.
After Planting
Water regularly during the first growing season to help the plant establish its taproot system, then reduce watering as it becomes drought-tolerant. The plant dies back seasonally as a perennial herb, so expect dormancy and avoid cutting it down until you see new growth returning. Moderate care requirements mean this isn't a fussy plant, but the biggest mistake is overwatering once established - let the soil dry between waterings, especially in summer.
