Collomia linearis is a species of flowering plant in the phlox family known by the common names tiny trumpet and slenderleaf collomia.

[2] This tiny wildflower is native to North America, where it is fairly widespread across the north and west.

[2] It is an annual herb, rarely exceeding 30 centimetres (12 in) in height,[3] with a velvety erect stem bearing long, narrow green leaves.

Atop the stem is a cluster of up to 20 white or light pink flowers, each about a centimeter across.

Each has five small rounded petals and stamens tipped with anthers bearing white pollen.
