Eriophyllum lanatum
species of plant

Eriophyllum lanatum, with the common names common woolly sunflower, Oregon sunshine and golden yarrow, is a common, widespread, North American plant in the family Asteraceae.
Description
Eriophyllum lanatum is a perennial herb growing from 30 to 60 centimetres (12 to 24 inches) in height, in well-branched clumps. Both the stems and leaves may be covered with a woolly gray hair, but some plants lack this. The leaves are 2.5–7.5 cm (1–3 in) long, linear on the upper stems, and slender and pinnately lobed on the lower stems. The hairs conserve water by reflecting heat and reducing air movement across the leaf's surface.
The flowers are yellow and composite, looking much like true sunflowers, and sometimes grow to about 5 cm (2 in) wide. Both the (8–12) ray and disk flowers are yellow, with one flower head on each flowering stalk. The flower heads have 6–14 rays, which are darker towards the base, and several disk flowers. They bloom from May to August. The seeds have scales at the tip.
The public source identifies “Eriophyllum lanatum” as species of plant. This brief keeps that definition visible, then builds a research path around Eriophyllum, lanatum and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Eriophyllum lanatum”, the useful work is to connect “species of plant” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q2592617. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
