Golden-yarrow

Eriophyllum confertiflorum, commonly known as golden yarrow or yellow yarrow, is a small evergreen subshrub in the Asteraceae native to dry slopes, chaparral, oak woodland and coastal scrub of California and Baja California. Plants form clumps 30 to 80 centimetres tall, woody at the base with slender, ascending, leafy stems that are loosely covered with fine, persistent woolly-white hairs giving a grey-green cast. The alternate, deeply pinnately lobed leaves are 1 to 4 centimetres long with narrow, often revolute lobes and are noticeably tomentose beneath. Flower heads are small, densely clustered into flat-topped corymbose cymes at the stem tips; each head bears four to six broad yellow ray florets surrounding a centre of golden disc florets and is subtended by a campanulate, woolly involucre of green phyllaries. The fruit is a slender, glabrous black achene crowned by a pappus of short, hyaline scales. Flowering occurs from spring into mid-summer.
