Least Water-lily (Nuphar pumila), also known as Yellow Pond-lily, is a beautiful aquatic plant species that belongs to the Nymphaeaceae family. It is native to North America and is found in still waters such as ponds, lakes, and slow-moving streams. This plant species is known for its bright yellow flowers and small size, which make it a popular addition to water gardens and aquatic landscapes.
The least water-lily has heart-shaped leaves that are typically green and floating on the surface of the water. The leaves are 1 to 4 inches in size and are supported by long petioles that allow them to float freely on the water's surface. The plant produces beautiful yellow flowers that bloom in the summer and early fall. Each flower is about 1 to 2 inches in diameter and has a distinctive bowl-like shape. The petals are arranged in a circle, and the center of the flower is filled with many small, yellow stamens.
In the wild, least water-lilies grow in shallow waters, typically 2 to 6 inches deep. They prefer still waters, but can tolerate slight currents. They are also well-adapted to varying water levels and can survive even in the driest of conditions. The plant is hardy and can tolerate a wide range of water temperatures, making it an ideal choice for water gardens in temperate climates.
One of the advantages of the least water-lily is that it is easy to care for. The plant is not demanding and can grow in a variety of soils, as long as they are well-drained.
