A semi-aquatic perennial with delicate blue forget-me-not flowers that blooms throughout summer. It thrives in wet or consistently moist conditions and is ideal for pond edges, streambanks, and bog gardens.

Why grow it

Water forget-me-not performs reliably in permanently wet conditions where many ornamental perennials fail, making it a practical choice for pond margins and streambank stabilization. Compared to terrestrial forget-me-not species, this semi-aquatic form tolerates standing water and seasonal flooding without decline. Its extended summer bloom and fine texture distinguish it from coarser marginal plants in wet-site palettes.

Watch out for

This species spreads readily via self-seeding in ideal moisture conditions; deadheading spent flowers can help manage spread where containment matters. In drier settings it may decline or require supplemental watering to establish, so siting in naturally wet microclimates rather than amended beds yields better results with less maintenance.
