Bi-color Lady Margaret

Something strange showed up in Pergola-tory recently  While doing my rounds, I discovered a mutant blossom on 'Lady Margaret' It had half red petals/sepals and half white. The extra strange part of this is that two of the sepals were divided down their mid-lines the same way - half red and half white. I'm not sure how the mutation occurred though between all the pests and the poisons, I'm not really surprised. I had hoped that the mutation would persist throughout that branch of the vine, but it did not. If it had, then I would have tried to propagate it and start a new variegated variety.
