Lobelia siphilitica (blue cardinal flower) has stunning spikes of beautiful lavender-blue flowers on light green foliage.  It flowers from August to September  just as some of the other pond plants are starting to fade, and is a great source of nectar for bees late in the season.  The unfortunate name is derived from the fact that it was used to treat syphilis!

Please note these may be cut back from May onwards, to remove the dominant central stem and encourage thicker bushier growth or to prevent the stems breaking in transit.
