Description

General: Perennial, white-woolly throughout, 1-6 dm. tall, usually several-stemmed from the base.

Leaves: Leaves variable, 1-8 cm. long, entire to pinnatifid or ternate.

Flowers: Heads solitary on long peduncles; involucre 6-12 mm. high, the bracts broad, erect and keeled; rays 8-13, yellow, 5-20 mm. long; disk flowers yellow; pappus a toothed crown, or a few chaffy scales. Fruit: Achenes slender, 4-angled.[2]

Bloom Period

May-August[2]

Distribution

Common on both sides of the Cascades from British Columbia to California, east to Montana and Utah.[2]

Habitat

Dry, open, often rocky areas at low to mid-elevations[2]

Uses

Wildlife: Butterflies - attracts orange sulfur red admiral comma and skipper butterflies.[3]

Propagation

May be collected as: Seeds. Collect whole fruiting heads when fruit is completely ripe from mid-summer to early fall. Collection restrictions or guidelines: None: common and unlisted Seed germination: Good germination after cold storage and fall planting in cold frames Seed life: Many years when well stored Recommended seed storage conditions: Dry down to 5-8% moisture. Store cold at 0-2°C. Propagation recommendations: Good germination from seed. Soil or medium requirements: Recommendation 1:1:1:2 sand:pumice:peat moss:fir bark Installation form: Direct seeding into site may reduce seedling dormancy or loss. Recommended planting density: Dense and patchy Care requirements after installed: Good drought tolerance, no after care with appropriate planting time. Normal rate of growth or spread; lifespan: Rapidly occupies a restoration site. Long-lived.[4]
