Thelypodium flexuosum is a species of flowering plant in the mustard family known by the common name nodding thelypody.

[1] It is native to the Great Basin and surrounding plateau habitat in the northwestern United States, from California and Nevada to Idaho.

Thelypodium flexuosum is a perennial herb growing from a woody caudex covered with layers of the dried bases of previous seasons' leaves.

It produces slender, branching, bending or erect stems up to 60 or 80 centimeters in maximum height.

The inflorescence is a dense, spikelike raceme of mustardlike flowers with lavender or whitish petals.
