About
A deciduous aquatic plant for shallow water with feathery, whorled fresh green foliage on crispy stems above the water and small red flowers from June to July. Although similar in looks to Myriophyllum aquaticum (which is banned under schedule 9 UK Wildlife and Countryside act as an invasive, non-native species), this aquatic plant is much less prolific and provides oxygenation for ponds.
