The native perennial wildflower still showing vibrant periwinkle blooms in the riparian buffer is Blue Lobelia Lobelia siphilitica.
It also is called 'Great Lobelia' or 'Blue Cardinal Flower'.
But don't confuse it with the annual plants or seeds sold in the garden stores lobelia erinus.
This native perennial forms clumps in the wetland around the pond and comes back every summer, blooming from July until frost in October
