Eriophyllum confertiflorum, commonly called Golden Yarrow or Yellow yarrow[citation needed], is a low growing shrub in the Daisy or Sunflower Family (Asteraceae), with wooly leaves when young, and yellow flower heads.[1] "Eriophyllum" means "wooly leaved.[1]

E. confertiflorum gets its common name from the similar appearance of its inflorescence to the true yarrow, Achillea millefolium, which has white flowers.[1]

Habitat and distribution[edit]

This is a highly variable plant which is generally a small shrub. It is native to California and Baja California, and its range may extend into Arizona. It can be found in a number of plant communities and habitats.

In the Santa Monica Mountains of California, it is common in open places that are away from the coast.[1]

Description[edit]

Growth Pattern[edit]

The plant grows in large clumps or stands of many erect stems often exceeding half a meter in height. Botanist Nancy Dale describes the growth pattern as "tidy".[1]

Leaves and stems[edit]

Leaves are alternate.[1] Leaves and stems[citation needed] are whitish when young, because of being covered in wooly white hairs, then become greenish[citation needed] to gray-green[citation needed].[1] Leaves have 3-5 deep lobes.[1]

Inflorescence and fruit[edit]

Yellow flowers are crowded in the head, which is up to 3/8", flat-topped, with both disc flowers and ray flowers.[1] "Confertiflorum" means densely flowered.[1]

It blooms from January to July.[1]

The fruit is an achene with a very short pappus.

The top of each stem is occupied by an inflorescence of up to 30[citation needed] flower heads, each bright golden yellow head with a large center of disc florets and usually a fringe of rounded to oval ray florets.[citation needed]
