I won't be having water-hyacinths

MyLotter, Always Smiling, posted about her water hyacinths and I thought they might be a nice option for me to have in a basin or small pond. When I researched, I found that they are a declared weed in Western Australia. It must not be sold and must be reported if seen, and destroyed. The danger is that the plant can choke waterways. Because the plant forms a thick blanket, it prevents the light from entering and depletes oxygen supplies. This causes algal bloom and impacts heavily on native fauna. Water hyacinth has the potential to choke waterways, preventing light entering and depleting oxygen, causing algal bloom and native fauna to die. There are a number of attractive plants which are ‘escapees’ and have become pests. One is the arum lily. It looks lovely along the creek beds in the south-west but is a menace to land-owners. So, no water-hyacinths for me. The photo is of water-lilies at Monet's garden in France.
