You might be lucky enough to spot the bright blue flower spikes of this perennial plant amongst other moisture loving plants growing alongside streams in the late summer. Much prized in gardens for its love of water logged soil where it will produce flower spikes above healthy bright green leaves. Very hardy and a reliable perennial.
