Amsonia kearneyana is a rare species of flowering plant in the dogbane family known by the common name Kearney's bluestar.

[1] Threats to the tiny native population include habitat destruction from livestock activity and flash floods in the river canyon.

It produces up to 50 hairy stems reaching up to 90 centimetres (35 in) in height, forming a hemispherical clump which may be nearly 2 metres (6 ft 7 in) across.

Its habitat is made up of riparian vegetation surrounded by Sonoran Desert scrub, in a transition between Madrean woodlands and chaparral.

[4] The specific name and common name are in honor of Thomas Henry Kearney, a botanist who specialized in plants of the American Southwest.
