Red elder tree flowers and fruits simultaneously

Self-tutoring about botany: the tutor shares an observation about a red elder.

I know of few trees that produce new blooms while their fruit is on. Yet, I (and now you, too) can witness a red elder doing so.

In the picture below, see the fruit at top left, the bloom at bottom right, on the same tree.
