One of our Allegheny Viburnums is blooming for the second time this season. It had set buds that I thought were for next year, and now suddenly, they're opened up. So the shrub has beautiful red berries from last spring's blooms, and new blooms. What will happen to these blooms whwn they don't have time to produce berries, and would it be a good idea to trim them off? Why would they be blooming again so late in the season? (I know...the weather!)
