Boechera retrofracta
Also called Second rockcress, Rock cress, Secund rockcress, Dangling suncress, Reversed rockcress
Reflexed rockcress is a biennial or short-lived perennial wildflower of the mustard family, native to cold northern and western North America. It grows wild on rocky cliffs, dry prairie and sand dunes, and is not a common garden plant, so care relies mainly on matching its dry, open, rocky native conditions.
Boechera retrofracta is a species of flowering plant in family Brassicaceae. The common names include reflexed rockcress.
Boechera retrofracta was listed as a threatened species in Minnesota in 1984 because of its rarity and the small size of its populations. In Minnesota populations are found in the Boundary Water Canoe Area in crevices on dry, north-and east-facing diabase cliffs, in association with other rare plants like: Physematium scopulinum (Rocky Mountain woodsia) and Asplenium trichomanes ssp. trichomanes (maidenhair spleenwort). There are also populations is Kittson county in dry prairie and sand dune habitat in association with xerophytes such as Juniperus horizontalis (creeping juniper), Orthocarpus luteus (owl clover), and Houstonia longifolia (bluets). It has also been found in bur oak savanna. In California it is found growing on rock outcrops, in sandy soil, in grasslands and sagebrush steppes, and in open conifer forests.
