Grew quickly in my pond edge and produced bright scarlet flowers all summer. Easy to maintain and doesn’t require much attention. Great for adding color to the garden.
Jake Quinn –
Planted it last spring and it’s already blooming. The flowers stand out well against the green foliage. I trimmed a few seed heads and it has produced more blooms since.

Perfect for a small pond. It thrives in the shallow margin and attracts bees and small insects. Very hardy and low maintenance.
