Comments

King’s crown is common around the Watershed, in higher elevation meadows and rocky slopes. The flowers are usually, but not always, unisexual (with either pistil or stamens, not both). The USA distribution—scattered in most states west of the Great Plains—shows disjunction, possibly reflecting the flower's survival during the last glacial period in high-elevation refugia, which may have included the Watershed mountains (Guest and Allen, 2014). Rhodiola integrifolia follows the Rio Grande drainage through New Mexico nearly to the Mexican border but no farther down stream.
