Gratiola officinalis
gratiole
This rhizomatous perennial gracefully forms clumps of upright stems, bearing linear to lance-shaped leaves with toothed margins and delicate small white summer flowers. Thriving in boggy conditions and at pond margins, this versatile beauty, also known as water hyssop, adds an exquisite touch to aquatic landscapes. Unfussy and non-invasive, Gratiola officinalis is a go-to choice for those seeking easy-to-maintain yet visually captivating flora in diverse water habitats.
How to care for Gratiola officinalis:
Plant out in reliably moist or boggy soil, or pot up into a pond basket and place at the margins of a pond in shallow water no deeper than 10cm (4"). A low maintenance plant, cut back foliage to ground/water level at the end of the year. Divide congested clumps in early spring every few years.
