This year, mine started blooming in a light pink color and have turned dark pink like your pictures of fall oak leafs. It is mid July. These plants are about 15 years old. We have had a very wet June and first week of July. Do you have any ideas or suggestions as to why this is happening and how to stop this in the future. I miss my white summer blooms.

Thanks, Andrea. I would speculate that this is weather related. Either an impact from last years drought and heat when the dlower bud was forming or as you described the wetter than normal conditions this year as the flower was emerging. I would expect it to be more normal next year. Your email address will not be published. This site uses Akismet to reduce spam.
