Plant Common Name
Brahmi, Herb-of-Grace, Water Hyssop
This low-growing, spreading aquatic perennial is a common water weed found along stream margins, pond edges and wet sands of the southern United States and adjacent Mexico. Its small, succulent leaves create a mat of foliage that becomes dotted with small, pale flowers. It creates attractive cover for waterway margins and makes a fine container specimen.
The small leaves of water hyssop are oval, lustrous and fleshy. From spring to fall, lots of small, single flowers are produced along the stems. These are bell-shaped and may be white, pale blue or pale pink. Butterflies pollinate the flowers and the resulting fruits are small and inconspicuous. This is the nectar and larval food plant for the white peacock butterfly (Anartia jatrophae).
Grow water hyssop in full to partial sun and provide it consistently moist, slightly acid soil that's not stagnant. Container grown specimens can be grown in potting medium cut with sand and gravel that's kept consistently moist or wet. Water hyssop looks attractive in hanging baskets, but great care must be taken to keep basket specimens well watered. Daily or twice daily waterings are needed. Water holding hydrogel crystals will help with moisture retention.
