I think your Buddleia is developing reversion back to the native
stock. Are the shoots carrying the mauve flowers growing more
vigorously than the others? A way of delaying this is to cut out the
mauve flower shoots. You would lose the pretty effect of the 2
colours on the same shrub but delay the inevitable eventual
progression to all mauve.
