Family

Scrophulariaceae

Botanical Name

BACOPA caroliniana

Plant Common Name

Blue Water Hyssop, Lemon Bacopa

General Description

This low-growing, spreading aquatic perennial is a water weed found along brackish water edges and wet sands of the southeastern United States from Maryland down to Florida and across to Texas. Its small, succulent, lemon scented leaves create a mat of foliage that becomes dotted with small, violet blue flowers. It creates attractive cover for waterway margins and is commonly half submerged making it an ideal aquarium or pondside plant.

The small leaves of lemon hyssop are oval, lustrous, fleshy and yield a lemon scent when crushed. From spring to fall, lots of small, single flowers are produced along the upright or spreading, partially submerged stems. These are bell-shaped and violet blue. Butterflies pollinate the flowers and the resulting fruits are small and inconspicuous.

Grow water hyssop in full to partial sun and provide it consistently moist soil that's not stagnant. This is a salt tolerant plant that can be planted near the Oceanside. Container grown specimens can be grown in potting medium cut with sand and gravel that's kept consistently moist or wet. It is ideal for wet, natural landscapes or aquarium tanks.
