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.
