I have Mary's Baby, too, and really like it. Also have:
Mary Lightfine (which is lighter)
Francis of Assisi
Wait Until Dark
All of them are in similar color ranges, some with more blue or more browny-red undertones. All are doing well in Texas' morning sun. Some have high shade after 1:00 or so for rest of the day, some have high shade from about 1:00 to about 2:30, then shade again from 5:30 through the rest of evening. Darker Shade, Quote the Raven, and Sanford Winery are darker/browner, but still with blooms good in sun.
People here are generous with advice and time, so I am sure you will receive many other suggestions.
