Water Violet
Hottonia palustris
A pretty perennieal oxygenator that has both attractive foliage and aerial flowers. Producing stolons (a shoot that bends to the ground or that grows horizontally above the ground and produces roots and shoots at the nodes) and erect stems, with whorls of light green leaves that are deeply divided, 2-13cm long and 6-10mm wide.
The pale lilac flowers which are 2-2.5cm across are borne on erect spikes 30-40cm (12-16") which emerge above the water in spring. The plant is not easy to establish and it performs best in shallow water in clear mud bottomed pools rather than being planted in baskets.
