Comments
Redroot buckwheat is typically found on well-drained rocky slopes, sometimes in association with Ponderosa, sagebrush, Chrysothamnus, etc. At times it can be found road side and on other disturbed ground. Watershed records of Eriogonum racemosum are mostly from the west side of the Valley and south of the Rio Grande. Two exceptions are a specimen found in the town of Alamosa in the Rio Grande floodplain (1985, Alamosa Co), and a specimen found just south of Lane 8N (Eightmile Lane) in Alamosa Co (2021, iNaturalist observation #90228121). These records mark the NE edge of the USA distribution, the center of which is Utah and Arizona. The species is much more common in the San Juan River drainage than the Rio Grande drainage, which it follows only as far as Socorro Co, New Mexico.
