About Least spatterdock
Nuphar microphylla, also known as the 'small yellow water-lily', is a charming perennial aquatic plant from the Nymphaeaceae family, native to North America. It is characterized by its small, dark green floating leaves and delicate, cup-shaped yellow flowers that emerge above the water's surface. It is ideal for small ponds, water gardens, and containers, adding a touch of serenity and color.

Care tips
This species prefers full sun exposure, at least 6 hours of direct light daily, for optimal flowering. It requires a nutrient-rich substrate at the bottom of the pond and a water depth of 15 to 60 cm. It's important to avoid excessive nutrients in the water, which could encourage algae growth, and to replant every few years to maintain its vigor. A common mistake is planting it in too large a pond, where its small flowers might go unnoticed.
