Hymenoxys grandiflora is a North American species of flowering plant in the daisy family known by the common names graylocks four-nerve daisy,[2] graylocks rubberweed, or old man of the mountain.[3] It is native to high elevations in the Rocky Mountains of the western United States.

H. grandiflora is a perennial herb up to 30 centimeters (1 foot) tall. The leaves are 7.5–10 cm (3–4 in) long.[4] The plant generally produces one flower head per stem, up to 10 per plant, present between June and August.[4] Each head has 15–44 ray flowers and 150–400 disc flowers.[5] The seeds are five-sided with narrow scales at the tip.[4]
The species has the largest flowers of any in its genus, hence the specific epithet grandiflora (large-flowered).[4]
