Definately do cut out at the base, all trunks in your CM that are blooming pink. Then be certain to pinch off any new growth that the roots of those cut off branches try to keep growing. If you keep the new growth pinched off then only those roots should suffer,and the white blooming branches should begin to experience an advantage, which helps them to prosper more. Unless it is just the lighting cast on the day you took that photo of the pink blooms, the pink blooming trunks might be a Biloxi Crape Myrtle. Those bubblegum pink blooms, in my opinion are a much nicer sight than some of the more pale easily washed out pinks that some CMs produce. Anyway I only tell you this to let your know that if you do like that particular pink color and would like to have a CM growing someplace else with that color, Than simply order or find at some local nursery a Biloxi Crape Myrtle that is already blooming and that you can confirm it really is a Biloxi Crape Myrtle.

I didn't see larger, older one at C.U.H. flowering after it was moved from the hotspot on the south side of the old Arboretum office to the open collections, where there was no reflected heat. Current location, on south side of C.U.H. seems to have brought about a return to regular flowering. Those planted out in the parking north of Douglas Conservatory will also be getting plenty of warmth off of the asphalt around them.

Too early. In my neck of the woods definitely not before the 20's of September. Few days ago on a way back home from JFK saw hundreds of them planted in open along highway. They were already in buds.

Hi @Kate Vasquez, I'm sorry, but my Acoma Crepe Myrtle was planted by a landscaping company about 15 years ago. I don't know where they sourced it, and even if I did, the availability as of 15 years ago likely wouldn't be relevant to where it can be sourced today. That being said, I have had good luck finding plants at Capitol Wholesale Nursery - and they've been able to special order plants for me when they didn't have them in stock. I had forgotten all about this thread til I got notified of your post. Since I'm back to answer your question, I'll also take the opportunity to say that with regard to my original question, I ended up planting a Muskogee crape myrtle with light purple flowers. I've been very happy with it and have not had any noticeable problems with powdery mildew. I'm attaching a pic taken today. Thank you to @BarbJP 15-16/9B CA Bay Area and @shedthechrysalis, who pointed me in the direction of the Muskogee variety 5 years ago!
