Hydrocotyle vulgaris
Also called White Rot
Hydrocotyle vulgaris, the marsh pennywort, common pennywort, water naval, money plant, lucky plant, dollarweed or copper coin, is a small creeping aquatic perennial plant native to North Africa, Europe, the Caucasus and parts of the Levant.
A low maintenance plant, it prefers to grow in reliably moist humus under a full sun or in part shade, indoors or outdoors, though it can tolerate full shade as well. It may also be grown as an aquatic plant in mud at the side of a pond or water garden in up to 2 inches of stagnant water. Despite its habitat in water, over-watering may still cause root rot.
In Britain it is the only native Hydrocotyle, growing in wet places such as fens, swamps, bogs and marshes. For example, it is a component of purple moor grass and rush pastures – a type of Biodiversity Action Plan habitat. The flowers rarely bloom; mostly self-pollination takes place. Vegetative propagation occurs through foothills. In wild plant gardens, the marsh pennywort is used for the planting of garden ponds, and also as aquarium plant.
