Boechera quebecensis

Boechera quebecensis, commonly known as the Quebec rockcress, is a critically imperiled herbaceous biennial or short-lived perennial flowering plant in the Brassicaceae family.

These locations are Cap du Corbeau, Rimouski (containing the largest extant subpopulation); La Muraille, Percé; Lac de la Falaise; Hâtée River, Rimouski; and Mont Saint-Alban, Forillon National Park (the smallest subpopulation, at three mature individuals).

[3] The species grows on limestone cliffs and escarpments at elevations 0 to 300 metres from sea level.

[5] As of December 2024, the conservation group NatureServe listed Boechera quebecensis as critically imperiled (G1) worldwide.

Climate change also potentially threatens this species by encouraging the expansion of forest cover in arctic-alpine regions.

[3] Boechera quebecensis was first named and described by Michael D. Windham and Ihsan Ali Al-Shehbaz in 2007 in volume 12 of the journal Harvard Papers in Botany.
