Several years ago I bought two Clerodendrum thomsoniae; onewhite w/ red centers and another one with completely red blooms. This June I re-potted both of them and a week or two later my all-red plant started putting out the white w/ red flowers. Why did it suddenly change? Did the new soil somehow trigger it? Clerodendrum thomsoniae with all red AND white/red flowers? My second all white/red Clero.
