Ludwigia repens is a species of flowering plant in the evening primrose family known by the common name creeping primrose-willow. It is native to parts of the Americas and it has the potential to spread easily and become naturalized in many areas. It is known as an aquatic weed in some regions. It is also cultivated as an aquarium plant. This is a mat-forming perennial herb with a creeping stem up to 30 centimeters long, rooting at nodes which come in contact with wet substrate. The leaves are oppositely arranged and up to 4 or 5 centimeters long. The flower has four yellow colored petals no more than 3 millimeters long nested on a base of four pointed sepals which may be slightly longer.
Creeping primrose-willow is fairly disease-resistant and typically does not suffer from many illnesses. Nonetheless, it can be vulnerable to pests and diseases present in its surroundings. Such infections are generally not severe. In terms of care, this plant requires a moderate level of maintenance. Regular pruning is necessary to keep it looking good and to support healthy growth. Fertilizing can also help encourage flowering. Creeping primrose-willow is suitable for anyone with an outdoor space, such as a garden or patio, and does not require much care experience. It may need more attention when grown indoors.
How to keep Ludwigia Repens.
Light
Creeping primrose-willow is native to habitats that receive abundant sunlight, such as the shallow banks of ponds and lakes. It prefers full sun, but can also tolerate partial sun.
Water
The creeping primrose-willow thrives in wetland areas, where it prefers consistently moist environments. While it can withstand short dry spells, it truly flourishes when it receives regular watering, ideally once a week. In outdoor settings, natural rainfall supports its growth and helps maintain its lush appearance.
Temperature
The creeping primrose-willow comes from tropical areas with characteristically warm, humid climates. As a result, it is well suited to high heat and humidity. It does not tolerate abrupt temperature changes and prefers a consistent thermal environment, so indoor temperature swings should be avoided. It generally cannot withstand cold and needs relatively warm conditions to grow. If temperatures fall too far, the plant may stop growing or may die.
Pruning
The creeping primrose-willow, with its reddish stems and vibrant green leaves, thrives in both aquariums and wet soils. To maintain its health, prune it lightly from early to late spring. This helps improve light penetration, water circulation, and foliage health while minimizing stress. Always use sterilized tools when pruning to prevent the spread of diseases.
