Eriophyllum confertiflorum (DC.) Gray | |
Eriophyllum confertiflorum, commonly called golden yarrow or yellow yarrow, 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]
Eriophyllum 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
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
Growth Pattern
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
Leaves are alternate.[1] Leaves and stems are whitish when young, because of being covered in wooly white hairs, then become greenish to gray-green.[1] Leaves have 3-5 deep lobes.[1]
Inflorescence and fruit
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 flower heads, each bright golden yellow head with a large center of disc florets and usually a fringe of rounded to oval ray florets.
