Thanks for the pointers on roses. While the SIL was living here and taking care of the place she let anything that popped up out of the ground continue to grow. and She planted a lilac right in the middle of the lawn without taking into account mowing between it and the fence to the neighbors yard.
When we still lived in Bridgeport there were some yellow roses that thrived and were small bloomed and yellow. And that was at 6,500 feet high sage and pinyon pine "desert" kinda like Wyoming in climate.
