- NEED IN SITU PHOTOS. For the Watershed there is one record of milk thistle, “in sweet corn garden at Center” (1961). The exotic Silybum marianum was sometimes cultivated for flower decorations, and may have escaped, but there is no record of it persisting. Escapes have been recorded in the more temperate regions of the USA, especially in California. The only other location in the Rio Grande drainage is Doña Ana Co of New Mexico.
