Bacopa monnieri, also known as Water hyssop or Memory Herb, is a versatile plant that can thrive as both a submerged oxygenator and a bog plant. With glossy, oblong leaves and small, fragrant blue blossoms, this fast-growing herb is perfect for creating a lush "carpet" on the surface of your garden or pond. It is a low-growing plant that blooms in the summer, requiring full sun to part shade to thrive. Bacopa monnieri is best suited for zones 7-9, making it a great addition to any garden or aquatic landscape.
