Talinum rugospermum Holz.[1]

Phemeranthus rugospermus is a species of flowering plant in the miner's lettuce family, Montiaceae, known by the common names prairie fameflower, rough-seeded fameflower, and flower-of-an-hour. It is native to the central United States.[2][3]

This perennial herb grows up to 25 centimeters tall with an erect branching or unbranched stem. The cylindrical leaves are up to 6 centimeters long. The pink flowers arise on a tall stalk. The capsules contain wrinkly seeds.[4] The flowers open for one day, and only in the afternoon.[2]

This species grows in open habitat where there is little competition from other plants, such as rock outcrops, stretches of sand, or open woods. It can be found on dunes along the banks of the Mississippi River. It benefits from low levels of disturbance, such as fires.[2] Human-caused forms of disturbance, such as off-road vehicle activity, can be beneficial at times.[3] Other plants in the habitat may include Andropogon scoparius, Selaginella rupestris, Opuntia compressa, Panicum virgatum, Allium stellatum, Isanthus brachiatus, Hedyotis longifolia, and Ambrosia artemisiifolia.[2]
