Platanthera elegans is a species of orchid known by several common names, including elegant piperia, coast piperia, hillside rein orchid, and hillside bogorchid.

This is a showy flowering plant native to western North America.

[1][2] It grows from a caudex tuber and sends up a thick stem just under a meter in maximum height.

The stem is topped with a cylindrical spike inflorescence of densely packed flowers with curving white to greenish-yellow petals.

[3][4][5] Coastal individuals are noticeably thicker and have more flowers than those that grow further inland; it is uncertain if these are variants, subspecies, or even separate species.
