Boechera perstellata
Also called Braun's rockcress, Braun's Rock Cress
Braun's rockcress is a rare, federally endangered perennial wildflower of the mustard family, native to shady limestone forests in Kentucky and Tennessee. It is not a commonly grown garden plant, so care notes below reflect general knowledge of wild rockcresses.
Borodinia perstellata, commonly known as Braun's rockcress and Nevada rockcress, is a rare species of flowering plant in the mustard family. It is native to Kentucky and Tennessee, where it is known from perhaps 25 total populations. Most of the occurrences have few individuals, and all are deteriorating in quality. The plant grows in shady forest habitat on limestone substrates, usually near streams or rivers. This is a federally listed endangered species of the United States.
Some authorities divide the species into two varieties, var. perstellata (small rockcress), which is mostly limited to Franklin County, Kentucky, in the vicinity of the Kentucky River, and var. ampla (large rockcress), which is known only from Tennessee. Other authorities do not divide the species and suggest any physical differences are caused by the local environment.
