Native Habitat:

Subalpine and montane meadows, open forests, and rocky slopes.

Bloom Time:

June – August

Growth Habit & Mature Size:

Perennial herb, 1–5 feet tall. Forms dense clumps of long, narrow, grass-like evergreen leaves. Produces tall flowering stalks topped with large, conical clusters of small white flowers. Plants may not flower every year, instead storing energy over multiple seasons.

Light & Soil Requirements:

Full sun to partial shade; thrives in acidic, sandy or rocky, well-drained soils. Adapted to summer drought and cold winters; often benefits from periodic fire in natural habitats.

Willamette Valley Native Companion Plants:

Gaultheria shallon, Vaccinium membranaceum, Eriogonum umbellatum, Festuca idahoensis, Arctostaphylos uva-ursi.

Urban Garden Function:

Provides striking architectural foliage and dramatic summer flower spikes in urban rock gardens, native meadow plantings, and dry, well-drained landscapes. Ideal as a specimen or structural accent in designs emphasizing texture, evergreen presence, and bold vertical form. Its fire-adapted nature and drought tolerance make it well suited to low-water landscapes.

Wildlife Supported:

Flowers attract native bees, bumblebees, butterflies, and other pollinators. Evergreen foliage offers year-round cover for insects and small wildlife. Nectar and pollen support high-elevation pollinator communities.

Historical Use:

Indigenous peoples used the long, tough leaves for basketry, cordage, and weaving. Valued ornamentally for its unique structural form, evergreen foliage, and dramatic floral display in naturalistic garden settings.
