    $\begingroup$ Maybe the tree was young so looking like bush. young trees sometimes can flower. $\endgroup$ – Always Confused Sep 10 '16 at 16:44
  • $\begingroup$ Not sure about the ID, but those are definitely flowers, not fruits. You can see some of the fallen blossoms on the leaves in one of the photos. $\endgroup$ – Clem C Sep 14 '18 at 21:08

Polygonum cuspidatum, common name Japanese knotweed. A notorious invasive species.

It's actually a herbaceous perennial (those stems grew in just one season, and will die back to the ground at the first hard freeze), not a shrub. The red things are ripening seeds, not flowers.

  • $\begingroup$ It is quite showy as it booms in cascades of silver flowers in late August that turn an intense magenta and then to scarlet each year right at time of the solstice. --Bitter Orange and Japanese Knotweed $\endgroup$ – iayork Sep 21 '18 at 13:27
