Spreading rockcress is a short-lived biennial or perennial wildflower of the cabbage family native to eastern North America, growing in dry, rocky, limestone soils. It is grown in gardens mainly for its early spring white flowers.
Arabis patens, commonly called spreading rockcress, is a species of flowering plant in the mustard family (Brassicaceae). It is a short-lived biennial forb native to North America. Its natural habitat is xeric soil, often on calcareous substrates. It produces white flowers in the spring.

In 2003 Ihsan Ali Al-Shehbaz moved the species, along with the other North American species of Arabis, to genus Boechera based on genetic and cytological data. In phylogenetic study published in 2010, Koch et al. placed A. patens in genus Arabis, in a North American clade that also includes A. blepharophylla, A. aculeolata, A. macdonaldiana, A. oregana, A. modesta, A. crucisetosa, A. nuttallii, A. furcata, and A. georgiana.
