Southeastern Colorado

The spring rains brought the flowers of Southeast Colorado  out of their dormancy and provided wonderful photo opportunities. We visited in late June, spending time in the Picture Canyon area of Comanche National Grasslands west of Campo and John Martin Reservoir State Park east of La Junta. Twenty-two new species were added to this website as a result

. Please contact us with comments and if you see errors in identification, and check back in a few weeks for more species.
