About Blue lotus

Nymphaea nouchali, also known as the blue lotus or blue water lily, is a stunning aquatic plant from the Nymphaeaceae family, cherished for its vibrant blue and purple flowers that gracefully float on the water's surface. Its round, floating leaves and star-shaped blooms make it a perfect choice for ponds, large water features, or spacious aquariums, adding a touch of serenity and exotic beauty. This species is native to Asia and Africa, and its flowers open during the day and close at night, offering a fascinating daily spectacle.

Native range

Tropical and subtropical Asia, including the Indian subcontinent and Southeast Asia

Care tips

For optimal growth, Nymphaea nouchali requires full sun, at least 6 hours daily, and should be planted in a nutrient-rich substrate at the bottom of a pond. Ensure the water depth is 30-90 cm above the tuber, allowing leaves and flowers to float properly. A common mistake is not providing enough sunlight or planting in poor substrate, which will result in sparse or no blooming. It is crucial to maintain clean, still water, avoiding strong currents that could damage the leaves and stems.
