Care Guide
Planting
Plant Bolander's Reedgrass in part shade, ideally in a location that mimics its native habitat of moist coastal areas and wet meadows. This grass thrives in consistently moist conditions, so choose a spot with reliable moisture rather than dry, sunny areas. Space plants according to their mature height of 2 to 5 feet tall, giving them room to develop their characteristic erect stems and spreading flower clusters.
After Planting
Water regularly during the first growing season to establish the plant in its preferred moist environment. This is a perennial grass native to northern California's wet habitats, so the biggest mistake is planting it in dry conditions or allowing the soil to dry out - unlike many ornamental grasses, this species needs steady moisture to thrive. Beyond establishment, maintain consistent soil moisture throughout the year to keep the plant healthy and vigorous.
