General information
Boechera falcatoria or Grouse Creek Rockcress appears to be an apomictic triploid hybrid between Boechera cusickii and B. pendulina and/or B. kelseyana. This species is restricted to Box Elder county, Utah though it may occur in Elko county, Nevada as well. Grouse Creek Rockcress can be found in rocky outcrops with sagebrush and mountain shrub communties between 2000 and 2320 meters (6600-7600 ft) elevations. This plant blooms primarily in the month of June, so watch out for its long stems, white to pale lavender flowers, and basal leaves covered in coarse hairs.
