Noccaea fendleri more commonly known as wild candytuft and alpine pennycress is a wildflower in the mustard family from western North America.

Leaves are attached to the base of the plant by a small stem (a petiole 0.4–7.3 centimeters long.

[3] The fruit is a type of pod called a silicle, two fused carpels that will split open when ripe.

It received its current classification and name in 1998 from the botanist Josef Ludwig Holub.

[3] It is a rare plant, only known from serpentinite rock outcrops in the Kneeland Prairie area of Humboldt County, California.

[3] It has a restricted range and is only found in central Idaho in Blaine, Boise, Custer, Elmore, and Valley counties at elevations of 2100–3700 meters.

[3] The species was scientifically named by Asa Gray to honor Augustus Fendler, who collected some of the specimens that were used in his 1853 description of it as Thlaspi fendleri.

[5] Noccaea fendleri is native to western North America from Washington state and Montana in the US[16] to Chihuahua, Coahuila, and Sonora in northern Mexico.

[11] It grows in alpine and montane ecosystems and prefers rocky slopes and forest openings.

[7] Wild candytuft is used in native plant gardens for its butterfly attracting white flowers.
