Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water new plants regularly until established. Mature plants are drought-tolerant and require minimal supplemental watering, especially in regions with adequate rainfall.
Cut back old foliage in late winter or early spring before new growth emerges. This removes dead material and encourages vigorous new growth. Avoid pruning in fall or winter to enjoy the dried plumes.
Easily propagated by division in early spring. Seeds can be sown in spring, but division is more common for maintaining desirable cultivars and ensuring faster establishment.
For container-grown plants, repot every 2-3 years in early spring. Choose a pot one size larger and use a well-draining potting mix. This prevents the plant from becoming root-bound and maintains vigor.
