Species of the Month August 2019


Frogbit (Hydrocharis morsus-ranae)


Frogbit is a small, free-floating plant of ponds, lakes, and still or slow-flowing waterways such as canals. It looks like a mini water-lily with green, rounded, kidney-shaped leaves, and a three-petalled white flower with a yellow centre. The petals often look thin and crinkly, and can appear to be translucent in bright sunshine.  Female flowers are solitary but the male flowers grow in twos or threes.
