Phonetic Spelling

Description

Blue Water-hyssop is a creeping native herbaceous perennial wildflower in the plantain family found in shores, tidal muds, marshes, disturbed wetlands, and coastal shores of the southeastern U.S.A. and Cuba. The thick succulent leaves are lemon-scented when crushed. This plant is heat tolerant, although it is not drought or salt tolerant. It is often used for aquaria, although plants commonly sold for aquaria are likely not the native species. 

In the wild it grows up to 40 inches long in a bog or semi-submerged condition, adapting well if flooded and fully submerged. It can be grown in or by the pond in warmer locales or as a houseplant in an aquarium or a shallow dish. It prefers semi-shade outdoors but requires bright light indoors.
