My first water lily flower! I bought a dwarf hardy water lily when the pond was set up (maybe 6 months ago). I chose this variety because my water depth is only about 50cm, and once the plant is potted up the water lily is only 10cm below the surface. The standard water lilies need 30-60cm of water. I planted it in a 20cm square pot filled with good quality topsoil and a 3cm layer of sand.
Here is the first bloom making its way to the surface (early Sept)
Here it is popping its little head above the surface to have a look around (mid Sept)
And today when I woke up...this is what greeted me! There is another bud on its way up to the surface too. The flower, seeds and rhizomes are all edible. You can dry out the rhizomes and grind them to make flour. I'll keep that in mind if I am stranded in a place where water lilies are growing wild.
