Description Eriogonum flavum is a perennial herb from taproot and woody caudex that forms dense mats in small areas, with leafless stems approximately 5–20 cm high. The dark green, 2.5–7 cm long leaves are spatulate-oblanceolate with long petioles. The plant is greenish above, while heavily whitish-tomentose below. This perennial herb re-emerges from taproot and woody caudex, and is likely long lived. Flowers late May to mid July. The inflorescence is a dense umbel (umbrella shaped clusters,) with leaf like bracts at its base. There is one heavily villous involucre, roughly 5–6 mm high per ray of the umbel. The perianth is 4–6 mm long, very hairy, and typically pale yellow. it produces an aroma, that is unpleasant to humans but attracts pollinating bees. Roughly half of the viable population produce flowers in a given season, and seed are uncommon, further supporting longevity. Downhill transport of seeds is primary way of dispersal, but wind probably
